Patterns affecting structural properties of social networking site Twitter
by Vinay Singh, Anurag Singh, Divya Jain, Vimal Kumar, Pratima Verma
Abstract: With invent of Web 2.0 technology, online interpersonal interaction has been turned into the sensation of twentieth century. Websites and other applications on the Internet provide large amounts of data and new research area to the researchers. Twitter is one of them. Structurally, this site is the complex network of users connected to each other whose nodes represent individuals or organizations, and links mimic the interactions among them. Understanding the graph is critical, both to enhance current frameworks and to plan new applications for this platform. Here, we will endeavor to study the mixing patterns possible in Twitter online social networking site due to the geographic locations mentioned by the user via measuring assortativity coefficient and find out how these patterns are affecting the structural properties of the network. We examined data gathered from Twitter online social network by crawling on this site using the open Application Programming Interface (API)available for us by Twitter. We obtained a small portion of this social networks graph and observed that assortativity is indeed present in this network and also when we ranked the user according to their followers count and then remove few of them from the dataset, we found that network is resilient to the deletion of highest degree nodes and assortativity still exists. We performed the same experiment with random users and found the same results. To validate the above property observed in this social network, we plotted the graph to show the presence of core components in the network.
Keywords: Mixing Patterns, assortativity coefficient, robustness, dynamics of a network, homophily
Evaluation of the StrAli-BPM approach: Strategic alignment with BPM using agreements in different levels
by Guilherme Salles, Vitor Barros, Marcelo Fantinato, João Albuquerque
Abstract: The strategic alignment between business areas and Information Technology (IT) is motivated by the needs of large organizations to thoroughly use the potentials of IT to transform business processes and deliver good products and services. In the treatment of processes and services, it is important to attend also to non-functional requirements, minimizing misapplied IT investments due to inefficiency. However, business process modelling languages do not represent these requirements, focusing only on functional requirements. Thus, in order to fill this gap, this paper presents the StrAli-BPM (Strategic Alignment with BPM) approach, which is divided in two parts BLA@BPMN and BLA2SLA: the former to extend the BPMN language aiming to embody non-functional requirements, in the form of BLAs (Business Level Agreements) enriched with KPIs (Key Performance Indicators); and the latter to semi-automatically derive a set of SLAs (Service Level Agreements), associated with web services, from a pre-defined BLA. This paper mainly describes the results obtained with the evaluation of the StrAli-BPM approach. First, the approach was evaluated by a proof of concept, based on the developed prototype tools, which allowed to verify its technical applicability. Then, a survey experiment was conducted with a panel of experts, members of a real organization. As a result, the proposed approach was well accepted by the experts who judged it as important and necessary to cover a gap in the BPM field. Some lessons learned from both evaluations are presented.

Sequence Clustering Approach for clustering Web User sessions
by Pradeep Kumar
Abstract: Clustering web usage data is useful to discover interesting patterns pertaining to user traversals, behavior and their usage characteristics. It is also useful for trend discovery as well as for building personalization and recommendation engines. Since web is dynamic, clustering web user transactions results in arbitrary shapes. Moreover, users accesses web pages in an order in which they are interested and hence incorporating sequence nature of their usage is crucial for clustering web transactions. In this paper, we present an approach to cluster web usage sequence data and removing noise using DBSCAN algorithm. We also study the impact of clustering process when both sequence and content information is incorporated while computing similarity measure. We use S3M (Sequence and Set Similarity) measure to capture both the order of occurrence of page visits and the page information itself, and compared the results with Euclidean distance and Jaccard similarity measures. The Inter-cluster and Intra-cluster distances are computed using Average Levensthein distance (ALD) to demonstrate the usefulness of the proposed approach in the context of web usage mining.
Keywords: Sequence clustering ; web usage data; similarity measures; Average Levensthein distance.
MULTI TERM BASED CO-TERM FREQUENCY METHOD FOR TERM WEIGHTING IN INFORMATION RETRIEVAL
by Santhanakumar Markandeyan, Christopher Columbus Chinnappan, Jayapriya Kalyanakumar
Abstract: Now a day, World Wide Web (WWW) has become the only source of all kind of information. Retrieving the relevant web pages based on user queries from WWW is an exigent task. Term Frequency Inverse Document Frequency (TF-IDF) is the most frequently used method for term weighting based on the occurrences and presence of a term inside the document. Retrieved document based on a single query term may not relate to the user search. This may lead the user to process the unwanted information. So, this paper proposes a new term weighting method named Co-Term Frequency, in which the weight is assigned according to the multi terms commonly occur in all documents. From the measures of precision, recall and F-score of the proposed method, it is clearly evident that the proposed framework retrieves the most relevant web pages when compared to other term weighting methods.
Keywords: Term Frequency; Inverse Document Frequency; Co-Term Frequency; Term Weighting; WWW; Precision; Recall; F-score.

The impact of the quality of the service from IS/IT departments on the improvement of operational performance: The point of view of users of technological innovations
by Ricardo Santa, Mario Ferrer, Liliyana Makarova Jørsfeldt, Annibal Scavarda
Abstract: The purpose of this article is to examine how the provision of services from Information Systems / Information Technology (IS/IT) departments helps organisations to achieve reliable operations and improvements in operational performance in the view of the users. A Structural Equation Modeling (SEM) was used to examine structural relationships between the set of observed variables and the set of continuous latent variables from responses of a sample of 138 individuals from large service organisations in Australia that had recently implemented Enterprise Information Systems (EIS). The results suggest that there is no direct influence of the quality of the service from IS/IT departments on the improvement of operational performance, but there is an indirect relationship through the achievement of operational effectiveness. The findings also suggest that focusing solely on the effectiveness of the technological innovation is detrimental to long-term operational benefits.

by Vijay Raghavan, Ben Martz, Morgan Shepherd
Abstract: This study compared two tabular presentations and one graphical presentation of the same rank order data to study differences in participant comprehension. Hypothetical raw voting data by ten different judges ranking ten states on the desirability of each state as a preferred place for retirement was used. Three sets of the data were constructed for the voting scenario with low, high and moderate levels of consensus. The summary data was a table (TABULAR) representing the total count of votes for each rank (first place through tenth place) for all ten states. It was also presented as a 3D cone infographic (GRAPHICAL) and raw voting data (RAW). Participants were asked to estimate the level of agreement (0.00 to 1.00) indicated by each presentation. The results showed that the graphical and tabular presentations differed in participant comprehension for low and moderate levels of agreement but not for high levels of agreement.

Online Car Parking Booking System: The case of Jordan
by Mahmoud Migdadi, AbdelRaouf Dado, Othman Al Safadi, Hisham Shadid
Abstract: With the increase in population and economic development of modern society of world, more and more people have cars of their own. The result is that traffic jam is more often than ever before. What is worse, in the increasingly crowded cities is the possibility of not finding safe parking lot especially in such crowded areas which could be a frustrating experiment. As parking facilities grow large, drivers need advanced methods of parking to reduce inefficiencies in finding spaces. A solution to reduce the drivers searching time for vacant car-park lots will greatly save time, reduce cost and improve the traffic flow in the car park areas. To this end, the researchers has created a web-based application (including PHP and MySQl server) which aims at providing its users (the drivers) several benefits-when they utilize it- such as provide real-time parking spot availability information in order to book a safe parking space any time and from any place, save them time and efforts, subscribe and pay electronically. In addition, the system allows parking owners and/or mangers to manage their own parking spaces bookings and subscriptions more efficiently.
Keywords: Keywords: Car parking; parking space management; web-based application; system analysis and design; Jordan.

Preventing Business And Information Technology Misalignment When Introducing Technology Changes
by Oscar Avila, Kelly Garcés
Abstract: Organisations introduce changes in order to adapt themselves to the extremely changing context. These changes often impact Information Technology (IT) and Business domains. In most of the cases, the scope of the organisational elements in these domains requiring adaptation is not well defined, leaving out elements, which can lead to misalignment. Thus, it is important to know the impact scope with the purpose of performing a full adaptation. When reviewing the literature in the Business-IT alignment research field, we found that there are no works dealing with this aspect. However, several works in adjacent areas have studied change management. In this paper, we report a systematic review of related work in these areas and extract a set of clues applicable to the Business-IT alignment domain which results in a change analysis framework and a set of rules to estimate impact scope and potential adaptation. Framework elements and rules are illustrated by means of an industrial case study
Keywords: Change Management; Information Technology; Business-IT Alignment; Strategic Alignment; Prevent misalignment.

Comprehensive Three-Layer Trust Management Model for Public Cloud Environment
by Vikas Kumar, Prasann Pradhan
Abstract: Public Cloud Offerings are gaining a lot of popularity as they offer consistent savings to the users by their pay-as-you-go model. Parties involved in public cloud transactions may be unknown to each other, however the users need to access the services of unknown cloud providers or third parties and even handover their significant data. Then the genuineness of the service providers or users becomes the most important concern. An established trust between the parties can help in creating sustainable transactions as well as long lasting business relations. To manage and build the trust, there is a strong need of trust management mechanism, which can fulfil the requirements from both the customer and provider perspective. Present work proposes a three-layer trust management model in public cloud environment, which can accomplish the expectations from both the viewpoints and can also support in building a long-term trustworthy relationships between them.

A New Technique for Data Encryption Based On Third Party Encryption Server (TPED) to Maintain the Privacy Preserving in the Cloud Environment
by Ashraf Aljammal
Abstract: As the cloud datacenters are exposed to a various types of attacks, data theft/leakage is considered one of the vital attacks that may affect datacenters credibility. In this paper, a new technique is proposed to store the users data in an encrypted form in the cloud datacenter via a third-party-encryption server. There-fore, the attackers and the datacenter authorities will be able to deal only with an encrypted form of the data. Furthermore, to decrypt the data, they need to know the encryption algorithm as well as the encryption key which is in turn placed on a third-party-encryption server. In addition, using third-party-encryption server (TPED) will lead to reducing the workload on both the cloud servers and the data owners machine.

A bottom-up approach for creating goal hierarchy using OLAP query recommendation technique
by Ranjeet Kumar Ranjan, Parimala N.
Abstract: Traditionally, data warehouses have been designed guided by an analysis of the underlying data sources. On the other hand, goal-oriented approaches build a goal decomposition structure which is further mapped to a data warehouse model. Goal-oriented approaches address the requirements of the decision makers. In this paper, we propose to build a goal decomposition structure for traditional data warehouses. As a result it can be assessed whether the existing data warehouse model satisfies the decision makers requirements. The approach is bottom-up wherein the tasks are identified first and the path to the strategic goal is built later. The tasks themselves are identified using OLAP query recommendation technique.

Reduced Energy Consumption for MC/DC Testing
by Sangharatna Godboley, Arpita Dutta, Durga Prasad Mohapatra
Abstract: After deployment, testing and validation techniques have become an important requirement for the reliability of software. However, these techniques do not measure energy that they consume, which is also an important parameter for software systems with short energy budgets. In this paper, we propose a new energy conservation technique. This novel technique does not affect the coverage percentage, but reduces the energy consumption. Energy conservation is based on test case minimization technique according to Modified Condition/Decision Coverage (MC/DC) requirements. Our experimental study shows that, as compared to existing work, our proposed approach achieves less energy consumption. On an average of five programs, we save 40.8% energy consumption

To Measure the Business Performance through Cloud Computing Adoption in Indian Scenario: Structural Equation Modelling (SEM)
by Rakesh Raut, Pragati Priyadarshinee, Manoj Kumar Jha, Manoj Kharat
Abstract: The purpose of this research article is to measure the business performance through Cloud computing adoption in Indian industries. Data collection was done through a questionnaire based survey that was completed by 660 managers from Indian industries. The derived hypotheses were tested using structural equation modelling. The results show that six out of eight hypotheses were supported for cloud computing adoption to measure business performance. The research model has been tested empirically through three phases: exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and structural equation modelling (SEM). The findings are: (1) trust is having a major impact on cloud computing adoption followed by perceived IT security risk, technology innovation, risk analysis, management style; (2) usage of technology and industry use are having very insignificant effect on cloud adoption rate. This research identified trust as a major factor influencing the cloud adoption rate. However, further research is required to fully understand all the aspects involved especially with the growing number of vendors available. Some more sub-factors can be derived for business performance which can be analysed through second-order SEM. In the final survey with 660 managers, two factors top management support and market place establishment have been confirmed and found are the most important criteria for cloud computing adoption. So, from this study service, manufacturing and power sectors are benefitted in terms of the business performance. This research provides original insight for cloud computing adoption within Indian industries from a managerial perspective.

EI-Annotate: An adaptive collective memory based on annotation ontology and context for decision making in economic intelligence
by Aissa Bensattalah, Faical Azouaou, Fahima Nader, Rachid Chalal
Abstract: In the decision support process, the economic intelligence actors use mental efforts and considerable cognitive activities to solve decisional problems; they deal with a large mass of digital documents during their activities. To facilitate their activities, they use different types of annotations on the manipulated document. To exploit the benefits of these annotations, we propose in this paper, EI-Annotate, an annotation tool dedicated to economic intelligence actors, which enables them to create an adaptive collective memory. The adaptive collective memory based on annotation ontology and context suitable for economic intelligence. This memory is a knowledge management tool that can support economic intelligence actors in their decision process. The EI-Annotate annotation module is implemented as extensions using different technologies; it enables to annotate resources in different formats (document, picture, videos). We present the results of an evaluation study of the proposed architecture of an adaptive collective memory conducted with a research laboratory context, regarding their annotation experience using EI-Annotate.
Keywords: economic intelligence; decision support process; unstructured decision problem; ontology; semantic annotation; context; adaptation; annotation tool.

Factors Affecting ERP Projects from a Project Management Perspective: A Literature Review
by Rateb Sweis, Ruba Abuhussein, Dana Jandali, Mohammad Mashaleh, Mutaz Al- Debei
Abstract: The purpose of this paper is to identify the factors affecting ERP projects and to classify them based on their project management knowledge areas. Previous studies were reviewed in order to identify the factors affecting ERP project performance. Next, the factors were categorized based on their project management knowledge areas. Finally, the knowledge areas were ranked according to their occurrence in literature. The results showed that, the four knowledge areas that affect ERP project performance the most are communication, human resource, time management and risk management. Understanding the factors that affect ERP projects has been a subject of considerable interest to many academics. Despite the many studies providing clear evidence on factors affecting ERP projects, vast majority of the literature has tended to approach the topic in a general manner while ignoring the issue of categorization of such factors. In this paper, we seek close such gap

Explaining and Predicting Continuance Usage intention of E-learning Recommender Systems: An Empirical Evidence from Saudi Arabia
by Hadeel Alharbi, Kamaljeet Sandhu
Abstract: This paper examines the factors that may influence students' acceptance and the continuance usage intention of e-learning recommender systems in higher education institutions in Saudi Arabia. A questionnaire was developed based on an extended technology acceptance model (TAM). A total sample of 353 university students from various universities in Saudi Arabia participated in this study. After performing the satisfactory reliability and validity checks, the hypothesized model was tested using structural equation modeling. The findings of this study revealed that perceived usefulness (PU) and perceived ease of use (PEOU) are significant determinants of e-learning recommenders system initial acceptance. The results also showed that the service quality, a newly added external construct, has significant impact on perceived recommender system ease of use. User experience of recommender system, the second newly added construct, was found to have a significant effect on perceived recommender system usefulness. Finally we found that students acceptance of e-learning recommender systems positively and directly influences their continuance usage intention. Overall, the proposed model achieves acceptable fit and explains 55% and 42.8% of the sample variance for this studys key target constructs (i.e. user acceptance and continuance usage intention of e-learning recommender system, respectively) which is higher than that of the original TAM. Our findings suggest that service quality, user experience and TAM factors (i.e. PU and PEOU) are important to consider in explaining students' acceptance and the continuance usage of e-learning recommender systems.
Keywords: E-learning; Adoption; recommender systems; TAM; Saudi Arabia.
Predicting e-commerce adoption in small hotel: the role of technology-organization-environment framework
by Nurhadi Nurhadi, Margo Purnomo
Abstract: This study aims at explaining the determinants of e-commerce adoption at firm level based on the technology-organization-environment framework. The population of this explanatory research included small hotels in Bali Indonesia which had implemented e-commerce system for at least a year. The result of the analysis showed that the four variables (relative advantage, organizational readiness, management commitment and external pressure) had a significant effect to the adoption of e-commerce system. Whereas statistically, the effect of the compatibility was not significant. Future researchers are expected to take more than one respondents as the informants in each of the selected hotel as the unit of the analysis. The result of this study proposed a practical implication suggesting that hotels need to consider the aspects of financial, technology, and human resources as an organizational readiness in implementing e-commerce system.

An Event-Driven Dynamic Cross-Layer Business Process Compliance Monitoring and Analysis Framework
by Sridevi Saralaya, Rio D'Souza, Vishwas Saralaya
Abstract: A key feature of any Business Process life-cycle is to persistently monitor adherence to compliance from various sources thus helping in detection, analysis and recovery from anomalies. Whenever a business process implemented as Service-Based System (SBS) deviates from compliance obligations it is imperative to overcome the anomalies, so that requirements of the business process are not adversely affected. This necessitates a monitoring and root-cause analysis process. Performance of the SBS is determined by several factors such as goals \& objectives of Business layer; output data, execution time \& number of services in Service layer; processing load, storage capacity, etc. of the Infrastructure layer. Current approaches to compliance monitoring are inadequate for this purpose as they observe and verify adherence to compliance properties in any one of the layers of the SBS. To identify the exact source of anomaly, the cause that may be rooted in any layer should be analyzed to propose effective recovery actions. We propose a monitoring and root-cause analysis framework capable of congregating and correlating events from all three layers of the SBS. The prototypical implementation based on event paradigm is non-invasive with the business process and hence introduces no overhead to the system under consideration.
Keywords: Cross-Layer Monitoring; Root-Cause Analysis; Event-Based Monitoring; Hierarchical Service-Based Systems; Dependencies.
A Three Pronged Technique For The Intelligent Ranking of Cloud Service Providers
by Tina Esther Trueman, Narayanasamy P
Abstract: Small and medium enterprise systems need to be preserved which is a necessity for our country as the growth is at the grass root levels. Cloud Computing can be a solution to help preserve the small and medium enterprises by promoting their services through the web as they can avoid huge infrastructure costs. However, most of the enterprise practitioners are not technology savvy, and it will be a daunting task to choose the best select service provider from the vast number of cloud service providers present. Hence, in this paper a comprehensive three pronged technique which will facilitate the easy selection of Cloud Service Providers is proposed. An Interval valued Fuzzy Soft Sets algorithm is used to rank the cloud service providers based on the user ratings of the cloud service providers. The information regarding the cloud service providers has been collected to create an ontology to match the service providers with user requirements. This suite of tools can be used by the enterprise owners to select the best cloud service provider for their requirements with minimum IT knowledge.

The Relationship between Business-IT Alignment and Organisational Performance: An Empirical Investigation from Multilevel View
by Hamad Balhareth
Abstract: The previous studies have significantly showed that Business-IT alignment is practically very important for the performance of the organisation. Its value is being derived from the influence of strategy on the outputs of the business. Hence, Business-IT alignment is recognised as very important for the profitability of the organisation. On the other hand, the previous studies have a limited focus on the two approaches: strategy content and strategy process, as impacting to the organisational performance. Therefore, this research study attempts to fill the gap in the literature and to test the relationship between Business-IT alignment and performance .The survey was conducted in universities along with assessing the contribution of strategy content and strategy process in the effects of strategic alignment on the performance. The data collected from the survey is used in the context of Saudi Arabia. The findings of the study show that the positive effects on the performance in the strategic alignment are statistically significant, where the effects can be varied in the absence of either strategic content or process.
Keywords: strategy process; strategy content; performance; business and IT alignment; Strategic alignment; misalignment; PLS analysis; empirical investigation.

What Managers Think about Big Data
by Ossi Ylijoki, Jari Porras
Abstract: Digitization progresses rapidly, producing vast amounts of big data. Companies can innovate their business models by using big data and related technologies. Some industries and companies are already on their way towards more data-driven businesses, but for most organizations this is an uncharted territory. The process is first and foremost a business transformation issue. Management leads the change and sets the pace; therefore the attitudes and intentions of executives towards big data are important in the transformation process. This survey concerns the behavioural intentions of Finnish executives with regard to big data. Building on a well-established technology acceptance model we explored the factors that explain the intentions. According to the results, executives intend to take actions that will promote the utilization of big data. They have either experienced or expect big data to be beneficial to their business, especially with regard to current products or services, streamlining of processes and increasing customer understanding. In addition to the generally positive attitude towards big data, the results reveal significant differences between respondents with big data experience compared to the inexperienced ones. The role of IT management seems to play an important role in the differences.

by SANTHOSH BABU A V, MEENAKSHI DEVI P, SHARMILA B
Abstract: Mobile ad hoc networks (MANETs) are the new generation of self organizing networks that offer unrestricted mobility without any underlying infrastructure. It relies on the cooperation of all the participating nodes. Due to diverse nature of MANET routing is the major challenge. Security for MANETS has become a difficult problem than the security in other networks. Authentication and encryption would be used as the primary defense. Second level of defense to detect and respond to the security problem called an Intrusion identification system. In this paper, two phased enhanced intrusion identification and response (t-EIIAR) system for multi hop cluster based MANETs is proposed. The two phases of the proposed method (1) cluster formation and cluster head selection (2) the enhanced identification and response system. The fuzzy c means algorithm (FCM) is used to form the cluster and the Intuitionistic Fuzzy TOPSIS (IFT) method used to calculate the trust value for each node in the cluster, based on the trust value select the cluster head and identify the intrusion levels. Finally the intrusion response action is performed from the intrusion level classifications. In the performance analysis, t-EIIAR system maximizes the intrusion detection ratio, network life time and minimum energy consumption in both transmitter and receiver side.

Implicit Feature Identification for Opinion Mining
by Farek Lazhar
Abstract: In Opinion Mining area, mining consumer reviews can give a finer-grainedrnunderstanding of consumer needs, which can efficiently help companies and merchants to improve the quality of their products and services. However, identifying features on which consumers express their opinions and sentiments, is not always a simple task. Some existing approaches that attempt to extract implicit features using opinion words as clues or co occurrence techniques lead to unsatisfactory results, and that due to the ambiguity caused by common opinion words which are often expressed on various features. In this paper, we propose, an approach based on Association Rule Mining (ARM) and classification techniques. The first step, consists of creating from a corpus, a set of association rules regrouping explicit feature-opinion pairs. The second step, consists to use this set to build a classification model able to predict for each given set of opinion words the appropriate target. Tested on many classifiers, experimental results show that our approach performs better when incorporating many opinion words than using single ones.

Managing Digital Infrastructures: Negotiating Control and Drift in Service Provisioning
by Nils-Petter Augustsson, Agneta Nilsson, Jonny Holmström, Lars Mathiassen
Abstract: The digital infrastructure literature provides important perspectives on the intrinsic relations between information systems in todays organizations. However, little attention has been paid to the challenges involved in providing requisite digital infrastructure services to organizations. In this paper, we argue digital infrastructure service providers operate in highly complex and uncertain environments. Rather than adopting a traditional approach to control, providers must therefore continuously negotiate a balance between control and drift as two complementary strategies.
Our argument is based on a retrospective longitudinal case study of a Swedish infrastructure service team within a large international firm. Using the encounterepisode process model as structuring principle and focusing on the tension between control and drift, we analyze the evolution of the providers efforts to manage a portfolio of digital infrastructure services over a period of ten years. Based on these analyses, we uncover the involved complexities and dynamics, how control efforts and drift constituted and how the infrastructure services were managed by continuously balancing control and drift. In conclusion, we relate the findings to extant literature to discuss new insights into provider management of digital infrastructure services.
Keywords: Digital infrastructures; services; management; control and drift.

A Semantic Matching Engine for Web Service Composition
by Rouached Mohsen
Abstract: One of the main assets of service-orientation is composition, which consists in developing higher-level services by re-using well-known functionality provided by other services in a low-cost and rapid development process. However, considerable differences on structural, semantical and technical levels along with the growing number of available Web services makes their discovery a significant challenging task. Therefore, services compatibility is an essential pre-requisite to service composition. Measuring the similarity of services is an important and valuable task to get useful information about their compatibility. Similarity measure can be considered as an optimization step before composing services since it enables to reduce the search time by classifying functionally similar services. This paper presents a practical approach to measure the similarity of Web services. Both semantic and syntactic descriptions are integrated through specific techniques for computing similarity measures between services. Formal Concept Analysis (FCA) is then used to classify Web services into concept lattices, and therefore generate a hierarchy of classes of similar Web services. Following this step, a composition engine takes as inputs the set of similar services and the specification of the required service, and generates the candidate composition plans that realize the goal. To determine the composition plan, the composition is reduced to a planning problem.
Keywords: Semantic Similarity; FCA; Web services; Composition.
Effective Selling Strategies for Online Auctions on eBay: A Comprehensive Approach with CART Model
by Yanbin Tu, Y. Alex Tung, Paulo Goes
Abstract: Most existing studies on selling strategies in online auctions do not distinguish auction heterogeneity when providing operational selling recommendations. They also tend to assume single objective for sellers. In this study, we incorporate seller and product heterogeneity into our analytical framework and implement data mining analysis in four auction segments. We use classification and regression tree (CART) to identify the critical factors along with their sequences for auction success and prices. We find different determinants for auction success and ending prices in these four auction segments. The classification and regression trees provide operational choices for sellers to build the most effective selling strategies. We propose that, by using expected auction prices with the classification and regression trees, sellers can integrate auction success and prices as multiple objectives in their selling strategies. Overall, this study contributes to the literature by providing an innovative methodology for effective selling recommendations, which can potentially lead to significant and smooth growth of the online auction market.

Release Cycle Management: An Action Research Study Into A Software Company
by Kamran Syed, Neda Barqawi, Lars Mathiassen
Abstract: Software is increasingly developed in a recurrent fashion. Still, we lack theoretical knowledge and conceptual models for continuously improving software release management in such dynamic contexts. In response, we conducted an action research study to improve Software Inc.s capability to recurrently release a specific software service, Secure-on-Request. Drawing on contextualist inquiry as theoretical frame, we addressed an initial problematic situation with a recent software acquisition, complexity of service delivery, new engineering and product management teams, and low process maturity to improve the organizations approach to software releases. As a result, we offer a detailed account of the process of, the content of, and the context for transforming release management at Software Inc. through the phases of diagnosing, establishing, acting and learning. Based on these insights, we theorize Release Cycle Management (RCM) as a key practice that integrates software process improvement into recurrent delivery of software. Moreover, we offer a conceptual model for RCM that software managers can use to implement such practices into their organizations.

CUSTOMER RELATIONSHIP MANAGEMENT AND THE IMPACT OF E-COUPONS ON B2C RETAIL MARKETS
by Alan D. Smith, James Shock, Robert Beaves
Abstract: As retail consumers are using mobile devices to access the Internet for information and actual purchases, retails are trying to create promotional campaigns that take advantage of this trend by offering digital coupons? However, there are a number of consumer preferences than marketers need to understand when creating marketing strategies. A survey addressed 5 factors that could affect a customers likelihood of utilizing e-coupons. It was hypothesized that customers will consider themselves loyal customers, but will change their purchase habits for retail (e.g., clothing and accessory purchases) and electronic goods due to an e-coupon offer. Customers disliked e-coupons with threshold values regardless of their annual income. Customers will consider coupon misredemption fraud as an issue for businesses in a negative light, but will admit to searching for coupon codes online. Most of the hypotheses were found to be statistically significant, suggesting management may need to re-evaluate its strategy the B2C retail industry and change how retailers implement e-coupon campaigns as a vehicle to drive CRM initiatives.

What Is More Important to Internet Banking Website Users: Usability or Functionality?
by Murat Durucu, Mine Isik, Fethi Calisir
Abstract: Unlike the past, the emerging trend is to provide online services due to the developments over the course of years. Online presence becomes the most significant factor of competitiveness. At this peak, firms try to infer the dynamics that increase customers acceptance of these services. The present study aims to identify the complex relationships among the various factors of usability and functionality. Analytic Network Process (ANP) was selected by the merit of its interdependence perspective to see the comparative effects of usability and functionality factors on Internet banking (IB) website selection. The information gathered through two questionnaires that conducted for Is Bank and Yapi Kredi Bank IB website users. The findings reveal that customers give higher priority to usability and usability-related factors, namely navigation and interaction rather than functionality. Another point worth mentioning is that information provision and security also prepossess the customer preference.

Information technology and the supply chain integration: A business executives context
by José Luis Martinho, Carlos F. Gomes, Mahmoud M. Yasin
Abstract: Despite the abundance of research dealing with the impact of supply chain management on todays organizations, such research tended to emphasize discreet relationships. A cross-sectional sample of Portuguese organizations are used to test several hypotheses pertaining to organizational resources, competencies, different levels of supply chain integration, and organizational performance. Based on the findings, the impact of information technology infrastructure flexibility exhibited mixed results on the constructs studied. Executive information technology competencies tended to positively influence the different types of supply chain integration. Internal integration was found to have a direct influence on organizational performance. Such internal integration is being encouraged by external entities including customers and suppliers. In this context, more integration might lead to more effective organizational performance. Therefore, it is concluded that organizations should integrate their resources, processes, and in the process encourage effective utilization of information.

Monitoring and Modeling Service Level Agreement of Multiple Virtual Machines in Cloud Computing
by Abdel-Rahman Al-Ghuwairi, Zaher Salah, Ayoub Alsarhan, Shatha Al Qudah, Ghadeer Al Qahmous, Aladdin Baarah, Ahmad Aloqaily
Abstract: Nowadays, Cloud Computing becomes the most widespread environment that provides several services over the internet. However, improving the customers' trust with cloud computing requires monitoring and ensuring the quality of the provided services continuously. Therefore, this paper provides a model for the process of monitoring the Service Level Agreement (SLA) to maintain specific Quality of Service (QoS) parameters. The proposed model assists in monitoring the cloud with multiple Virtual Machines (VM's) in the same environment, which belongs to the same customer. The core foundations for this model are: SLA, QoS parameters, multiple VM's and violations' penalty assessment. This model helps in enforcing and monitoring the service level agreement (SLA). Moreover; observing the quality of service within multiple virtual machines environment, which is described as complex, resource consuming and imposes workload over the cloud system. The proposed model for monitoring the (QoS) parameter in multiple VMs environment works dynamically and checks for any violation. Moreover; the penalty for each violation will be calculated and informed to the customer and provider at the same time. The same SLA which belongs to the same customer and a specific provider will be monitored and managed through multiple VMs. The proposed model depends on the time factor while running the VMs in sequentially manner with a short period of time as a gap between each VM. The proposed model will prevent any interception between VMs and can maintain synchronization.
Keywords: Cloud Computing; Service Level Agreement (SLA); Quality of Service (QoS); Multiple Virtual Machines (VM's); Violation Penalty.

Building Federated Data Warehouse Schema Using Web Service Approach
by Nouha Arfaoui, Faiçal Felhi, Jalel Akaichi
Abstract: The data warehouse is considered as a repository that stores data from disparate sources. It is used mainly in the process of decision making.
Because of the diversity of the applications, their heterogeneity and their physical spacing, building a data warehouse, to make decisions in a federated architecture, is a very complicated task. To overcome this problem, we propose a new approach for the design of a federated data warehouse schema based on the web services. The latter are applied because of their capacity to solve many technical problems related to the integration of data source in a federated environment. The proposed solution is based on the bottom-up approach where the data warehouse schema is generated from the set schemas of the data mart. It is composed by two steps. In the first one, a web service is used to generate the schemas of the data mart one for each data source. In the second step, a second web service is used to merge the generated schemas to build the final schema of the data warehouse.

Defining One Product Data for a Product
by Risto Silvola, Arto Tolonen, Janne Harkonen, Harri Haapasalo, Tarja Mannisto
Abstract: The growing importance of product data management and master data necessitate companies to have practices for deriving product master data from their corporate strategy. Business drivers need to be understood from the perspective of corporate strategy to capture product master data in relevant systems in a straightforward manner. Ideally master data is created only once and used through the life-cycle of the product. This study clarifies the foundations for determining one product data from corporate strategy. Data definitions are analysed to understand its linkages to business drivers, whereas main business processes are used to support categorisation. The practices of three companies are analysed to understand how business drivers for new products impact product data requirements. The results highlight the importance of business drivers in defining one product data based on the product master data, business-process related product data and IT systems over the product life-cycle.

A study of Feature Selection techniques for predicting customer retention in Telecommunication sector
by E. Sivasankar, J. Vijaya
Abstract: Churn is a termination of a contract between customer and company or quitting customer using the product or service. The goal of Churn Management (CM) is to reduce customer losses and retain profitable customers. Churn prediction is an important measure that leads to the solutions for the development of any business or industry; mainly it has lots of impact in telecommunication field. The eventual aim of the organization is to retain the existing customer base, because adding new customers may need investment of money, human resource and additional time. In the current era many researches and industries focus on effective research on churn prediction. Based on the analysis of works performed in the past, it is comprehended that there is some lagging in identifying necessary features in the telecommunication field and also the performance of the telecommunication sector is challenging due to the highly complex dimensional data sets.Feature selection is the process of eliminating irrelevant features from the data set, while maintaining acceptable classification accuracy. The selected features play an important role which can directly influence the effectiveness of the resulting classification. In this paper, a methodology is proposed consisting of two phases, attributes selection and classification based on the attributes selected. Phase one uses a Filter and Wrapper method for attribute selection with Random over-sampling (Ros) through which the size of attributes set and misclassification error can be reduced. In the second phase, the selected attributes are taken as inputs by classification techniques like Decision Trees(DT), K-Nearest Neighbor(KNN), Support Vector Machine(SVM), Naive Bayes(NB) and Artificial Neural Network(ANN). In this work the data set KDD Cup 2009 is used for evaluating the performance. Finally True Churn, False Churn, Specificity and Accuracy are measured to evaluate the efficiency of the proposed system and it is found that the above mentioned methodology performs well ahead for churn prediction and suits well for the telecommunication sector.

RELATIVE EFFICIENCY OF SOCIAL CRM SOFTWARES: A HYBRID FUZZY AHP/DEA APPROACH
by V. Raj Kumar, L. Suganthi
Abstract: In todays tech-savvy society, social media platforms revolutionize the way in which people communicate and share information with each other. These platforms enable customers to instantly and openly convey their opinions, criticisms and praises on various topics pertaining to products and brands. Hence it becomes imperative for organisations to integrate social media information into their CRM strategy. In this paper, relative efficiency of the Social CRM packages using fuzzy AHP/DEA:AR-CCR was determined by considering price as the input criterion and functionality, product quality and customer support as output criteria. Using fuzzy AHP it was found that product quality (41.66%) is the most important criteria followed by functionality (33.29%) and customer support (25.05%). Pipedrive and Really Simple Systems were found to be relatively more efficient. In this manner a Social CRM package that best fits an organisations customer-centric work culture is selected. The Social CRM vendors can utilise these results to benchmark their packages against their competitors.

An Adaptive Algorithm for Frequent Pattern Mining over Data Streams using Diffset Strategy
by Subbulakshmi Balasubramanian, Deisy Chelliah
Abstract: Frequent pattern mining using sliding window over data streams is commonly used due to its wide applicability. Determining suitable window size and detection of concept change are the major issues and can be addressed by having flexible window based on amount of changes in frequent patterns. For mining frequent patterns over data streams, vertical mining algorithms can be used. However, in these algorithms, size of transaction identifiers (tidsets) and the time for computation of intersection between tidsets is large. Moreover, presence of null transactions does not contribute any useful frequent patterns. A new algorithm called Recent Frequent Pattern mining based on Diffset with Elimination of Null Transactions (RFP-DIFF-ENT) over data streams using variable size window is proposed. It stores difference of tidsets and eliminates null transactions which minimize memory and mining time. Experimental results show that proposed algorithm saves computation time, memory usage and minimizes the number of frequent patterns.

Abstract: Tourism is an attractive sector for economic development as it offers potential economic benefits for developing countries. Most tourism sectors throughout the globe consist of Small and Medium-sized Enterprises (SMEs) and as such, tourism SMEs (SMTEs) utilization of Mobile commerce (M-commerce) is crucial in terms of added efficiency, effectiveness and innovation. However, there is a low level of acceptance for M-commerce applications in SMTEs in most developing countries. In such countries, effective applications and factors that impact the acceptance rates of M-commerce in SMEs, is still in the early stage. More importantly, the factors impacting the application of M-commerce are still ambiguous and the relevant theories for M-commerce acceptance have largely been untouched in literatures in the context of developing countries, particularly in Jordan. The paper aimed to test the factors influencing the acceptance of M-commerce application among SMTEs. The questionnaire was distributed to the target sample and the obtained data from questionnaires was analyzed through the SPSS statistical software. Results of the analysis revealed that all factors positively influenced behavioural intention to use M-commerce application in such enterprises. The study provides advanced knowledge of users acceptance of M-commerce in SMTEs, which will help the M-commerce providers in such enterprises to understand the factors that influence the acceptance of M-commerce in SMTEs, which in turn, plays an important role in increasing the acceptance level of M- commerce in SMTEs.

Secure Cluster based Data Aggregation in Wireless Sensor Networks with Aid of ECC
by C. SriVenkateswaran, Sivakumar D.
Abstract: Wireless sensor networks are widely deployed for wide range of applications for gathering information about the desired application. In general, sensor nodes sense their environment, collect sensed data and transmit it to the base station. During this transmission of sensed data from node to sink there is a lot of energy get reduce. In-order to overcome this problem, some of the researchers used cluster head-based approach to send the data to the sink node. The cluster heads collects all traffic from their respective cluster and performs data aggregation before transmitting the data to the sink. In this paper, we have presented the approach for cluster head selection for data aggregation in wireless sensor network. For clustering the node, the proposed method is use hybrid k means and fuzzy c means clustering algorithm. Then we select the cluster head from each cluster. Every node in the wireless sensor network sends their sensed data to the cluster head. The data aggregation is done in the cluster head. Finally base station is received the data from one cluster head, in order to reduce the transmission time here the proposed method is remove the duplicate data and then secure transmission is done by Elliptic curve cryptography (ECC). The performance of the proposed technique is evaluated by overall running time and also the encryption and decryption time. Finally, the simulations are performed and the results are analyzed within the simulation set up to determine performance of the proposed algorithm in the sensor network.

Designing an e-commerce recommender system based on collaborative filtering using a data mining approach
by Samira Khodabandehlou
Abstract: E-commerce recommender systems have been converted to a very important decision-making helper for customers, due to the wide variety of goods and services offered by e-commerce companies. These systems provide online personalized recommendations using information technology and customers information. In the meantime, Collaborative Filtering (CF) recommender systems are one of the key components of successful e-commerce systems. Despite the popularity and successes of CF, these systems still face a series of serious limitations, including cold start, Sparsity of user-item matrix, scalability and change of user interest during the time that impede exact recommendations to customers. Although much research has been presented to overcome these limitations, but no comprehensive model is yet offered to reduce them. Therefore, the present research aims to eliminate the limitations of CF and to provide a comprehensive system by employing a set of data collection methods in order to present the best and most reliable recommendations to customers for product selection. The proposed system has been implemented in 5 stages including: 1. Customer segmentation based on LRFM variables in the level of product category to evaluate the Length of customer relationship with the company, Recency, Frequency, and Monetary of purchasing product categories 2. Extracting association rules based on user-category matrixes in the level of each cluster 3. Customer segmentation according to demographic variables 4. Change of user-item matrix and reduction of its dimensions 5. Developing a new similarity function by weighted combination of results of segmentation methods and CF. According to the gained results, the proposed system of this research has resulted in the removal of traditional CF constraints and presenting more accurate and appropriate recommendations for the preferences of customers.

E-Government Procurement Implementation in India: Evolving Decision Parameters for Project Success
by Prabir Panda, Ganesh P. Sahu, Babita Gupta
Abstract: Research indicates that up to 25% savings can accrue to the Indian Government by migrating to E-Government Procurement (E-GP). Thus improved utilization of public procurement (valued 3.4% to 5.7% of Indian GDP) would have significant impact on the overall efficiency in the government spending. However, E-GP projects, like any other e- Governance projects, have 70% chances of failure. This paper empirically studies stage-wise importance of eleven critical success factors (CSF) that were identified through extensive literature review in E-GP project outcome in the Indian context. We developed a research model for ascertaining the impact of identified CSFs on various stages of E-GP evolution building on the models of Layne and Lee (2001). Pinto and Slevin (1987), and Nasi (2005). Literature review, did not yield any study that focused on E-GP in India. Therefore, we conducted an exploratory study to understand the status of E-GP implementation in India and for fine-tuning the research model. A survey of the stakeholders involved with the E-GP system in India was conducted for testing eleven hypotheses related to eleven CSFs. We used regression analysis and mean score to empirically test the relationships identified between the CSFs and E-GP project success. The results show that five of the eleven CSFs are not important at stage 2 of E-GP project evolution, while all eleven CSFs contribute to the E-GP project success in Stages 3 and 4. This study is one of the few empirical studies conducted on the stage-wise analysis of CSFs in the E-GP domain and the first one to focus on E-GP projects in the Indian context. This study makes a significant contribution in the formulation of India specific CSF based parameters for managerial decision making for the E-GP project managers.

Abstract: This paper introduced the employing of information retrieval techniques and statistical techniques in producing Systematic Literature Review (SLR). Sentiment Analysis (SA) and Opinion Mining (OM) in social media domain were considered as a case study to produce an example of SLR. The produced SLR introduced the field of sentiment analysis and opinion mining and surveyed current issues in user content based mining in social media field. The main aim of the research work described in this SLR was to investigate the use of sentiment analysis and opinion mining techniques for the analysis of social media. Social media has become one of the most important electronic phenomena in the present age; where everyone can access these networks such as Facebook, Twitter, Google+ and LinkedIn to broadcast their daily news or to express personal opinions or their sentiment orientations toward various subjects. As a result, a huge amount of data transmitted daily by users around the world and thus it may be impossible to deal with such a huge amount of data and analyse it manually. Therefore, researchers have conducted several research studies to discover new approaches, tools and techniques that can be used to analyse and explore such huge amount of data; more specifically data that are generated through social media websites. Systematic literature reviews retrieve and evaluate the multiple relevant research papers concerning specific research questions. In response to the lack of current systematic literature reviews concerning the Opinion Mining and Sentiment Analysis in Social Media, the authors present this comprehensive systematic review to introduce the field of sentiment analysis and opinion mining techniques applied to the data originated from social media and surveys the current issues and challenges for sentiment mining in the context of social media. The paper first detailed different approaches for conducting opinion mining and sentiment analysis and provided a common framework for searching and selection procedure applied to extracting the research papers that covering comprehensively the intended research directions in the field. It then discussed the most common techniques found in the literature for conducting opinion mining and sentiment analysis, which aims basically to determine whether an opinion expresses a positive or negative sentiment polarity in order to use this predicted polarity in further analysis or extensions. This systematic review investigated the opinion mining and sentiment analysis techniques that are found in more than 60 specialised research papers in the field of data mining with respect to social media in a systematic manner.

A Structural Equation Model to Assess Behavioral Intention to Use Biometric Enabled e-Banking Services in India
by Ruchika Gupta, Siddharth Varma
Abstract: India has one of the largest and rapidly growing population of internet users in the world. Yet it seems that Indian banking industry has not been able to utilize this opportunity. This is reflected in a recent survey which showed that only a meager percentage of internet users does banking transactions online in the country. Security risks have been one of the prime reasons for such restrained usage. Biometric technology presents a viable solution to get over such security risks. The objective of this study is to assess the adoption of biometric enabled e-banking services in India. The paper primarily focuses on evaluating the customers behavioral intention to adopt such services. The Technology Acceptance Model has been used to determine customer intention to use biometric services. A sample of 200 respondents has been analyzed. In the first step, Confirmatory Factor Analysis (CFA) has been carried out and subsequently a Structural Equation Model has been developed using AMOS. Hypothesis testing has been done to develop the model. The study is based on a survey conducted in the National Capital Region of Delhi which includes Delhi and surrounding areas adjacent to Delhi. Perceived Ease of Use was found have a positive relationship with Perceived Usefulness which in turn was an important factor in determining Attitude towards the technology. Attitude was found to be a strong determinant for Behvioral Intention to use the technology. Demographic factors: age, income and prior use of Internet Banking were found to have no significant effect on the Attitude towards use of the technology. The implication of this result is that intention to use biometrics in banking services is unaffected by these three demographic factors which is positive news for use of biometrics. Moreover, Ease of Use has to be kept in mind while designing such systems.

Ontology based Feature-Level Sentiment Analysis in Portuguese Reviews
by Larissa Freitas, Renata Vieira
Abstract: Sentiment Analysis is the field of study that analyzes peoples opinions in texts. In the last decade, humans have come to share their opinions in social media on the Web (e.g., forum discussions and posts in social network sites). Opinions are important because whenever we need to take a decision, we want to know others points of view. Opinions may be looked at considering different levels. A general opinion expressed in a whole text or review, in a sentence, or even parts of the sentence, when one finds to figure out what are the particular features that are liked or disliked regarding a certain product, entity or event. In this work we study this more detailed level of analysis, which is called the aspect-level or feature-level. This more detailed type of analysis requires going deeper in the parts of a sentence and an effort to deal with their meaning, therefore knowledge rich approaches are specially useful. For that we use ontologies, as they can be used to represent the relevant aspects of entities, in a semantic organized way, for instance, aspects that are part-of or properties of an entity in a certain domain of knowledge. Our approach is built for Portuguese and is evaluated on a reviews data set of the accommodation sector.

Dynamic Changes of QoS Parameters in Cloud Computing Service Level Agreement
by Abdel-rahman Al-ghuwairi, Mohammad Khalaf, Zaher Salah, Ayoub Alsarhan
Abstract: Cloud computing is considered one of the most important topics in software engineering research trends. It provides many advantages and benefits for all users whether they are organizations or individuals, by compromising the needed resources and services. These resources and services could be classified into three categories: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Service Level Agreement (SLA) is a contract between cloud user and cloud provider in cloud computing environment. This contract is needed to manage, control, and monitor these services. Also, SLA is considered an essential document or factor to manage the relationship between the cloud user and cloud provider in cloud computing. SLA can be defined as a contractual agreement signed between cloud user and cloud provider in order to manage the level of access for the resources and quality of services provided. Continuous changes of technologies and requirements make updating SLA an urgent priority for both cloud user and cloud provider to ensure that the services provided are meeting their needs among multiple Quality of Service (QoS) parameters. Coping with multiple and frequent changes in QoS parameters is considered the main reason behind the intensive studies that have been presented for building a dynamic SLA. The current dynamic SLA monitoring approaches have considered the cloud provider view only; on the other hand the cloud user side view has been ignored. To solve the user concerns in dynamic SLA monitoring system, this paper proposed a dynamic SLA monitoring approach in IaaS system by generating new SLA terms based on analyzing the SLA penalties. This research paper applied a new proposed tradeoff mechanism between monthly cost and QoS guarantee values. This research paper proposed a dynamic model for updating QoS parameters of SLA in cloud computing environment. Java language was used with a QoS measurement dataset to experiment the proposed approach. Moreover; the selected database is used to compare the Static SLA (SSLA) approach with the proposed Dynamic SLA (DSLA) approach. The results of this experimental study show that the number of SLA violations in DSLA approach are less than the number of SLA violations in SSLA approach.

Prioritizing Mobile Learning Application Requirements
by Asharul Khan, Zuhoor Al Khanjari, Mohamed Sarrab
Abstract: Mobile technology has become an integral part of human life. Nowadays people have started using mobile devices and communication network in different domains in the form of mobile education, mobile commerce, mobile health, and mobile tourism. The mobile application development research, especially Mobile Learning (M-Learning) is still in infancy. M-Learning application development is affected due to changing users requirements and technology. M-Learning stakeholders face difficulty in reaching consensus on the available requirements implementation priority during design and development of M-Learning application.
The solution to this problem lies in requirements prioritization. The review of existing literature has revealed a number of prioritization techniques. However, the common challenges to all these techniques are that they are too complex, time-consuming, and difficult to use by the novice users in M-Learning domain. There is insufficient research to draw firm conclusion on suitable method for requirements prioritization in M-Learning application development.
Therefore, this paper presents a requirement prioritization scenario for M-Learning application development. The requirements prioritization scenario has four steps. The first step is the identification of stakeholders. In the second step, the stakeholders are asked which requirements would be implemented in the First F or Next N cycle of application development. The next step is the analysis of the stakeholders prioritized requirements by analyst based on the requirements prioritization scenario rules. The last step involves the final decision by the analyst for any changes in the already prioritized requirements due to time, costs or any other constraints which are beyond the understanding of stakeholders. The process is repeated iteratively. The requirements prioritization scenario is implemented in a case study to understand the feasibility in the actual use.

Barriers to Crowdsource Software Development: Evaluating the intertwined effects
by Nitasha Hasteer, Abhay Bansal, B.K. Murthy
Abstract: The techniques to develop software have grown with time owing to the latest technological advancements. Cloud computing has changed the application development landscape. With the advent of this distributed computing, collaborative development by way of crowdsourcing the development of software artifacts, is gaining popularity. Using a cloud to outsource software development to a crowd of developers is an emerging form of software development. Developing software through crowdsourcing enables accommodating to the changes in the rapidly growing software industry in a convenient way. While on one hand crowdsourcing has merits of providing diverse innovative solutions with no investment in the manpower. On the other hand a creative intelligent task like developing software through crowdsourcing is constraint by the barriers to successful implementation. In this work we identify through literature and report the barriers to crowdsource cloud application development that hinders the maximum advantage that could be drawn out from the service oriented paradigm. We use the Decision Making Trial and Evaluation Laboratory technique to analyze and determine the direct and indirect intertwined effects amongst the identified barriers. From the results, we infer that granular nature of changing technology, lack of trust on crowdsourced platforms, lack of understanding on intellectual property issues and security apprehensions are classified as the root causes that affects coordination and collaboration amongst the contestants of the crowdsourced platform, among other barriers.

Implementation of the COD Payment Method on E-commerce Websites in the Arab Region
by Mohanad Halaweh
Abstract: The cash on delivery (COD) payment method has been increasingly used in recent years as a method of payment in e-commerce transactions. However, research within the e-commerce field to determine how widely this payment method has been adopted is limited, especially from the e-commerce websites perspective, at the global level, and specifically in Arab countries. Therefore, the aim of this paper was to study the current use of COD in the Arab region by evaluating e-commerce websites that accept this payment method. Twelve popular e-commerce websites were selected for this study and evaluated based on three criteria: acceptance of this payment option, visibility of this payment option on the website, and the clarity of related terms and conditions, including charges, international delivery, and others. The research findings showed that all surveyed e-commerce websites have adopted the COD payment method in addition to other e-payment options. The findings also revealed that there is no consistency in the sign/icon/image used to indicate acceptance of this payment method or where it is located on the website. Results also revealed that there is lack of clarity in policies pertaining to this payment method. The interpretation of the research findings and implications for e-commerce theory and practice as well as future research are discussed.

Measuring Internet Addiction In Europe Based Knowledge Societies: A Case Study Of France
by Habib Ullah Khan, HELMI HAMMAMI
Abstract: The technological evolution has put a new challenge, internet addiction along with the internet technology before the world. The much evolved internet addiction literature could not find a common solution to assess the nitty-gritties of it. That is, though many scales are developed to test the cause and effect of internet addiction, their subjective nature probed for the present study. The study intended to collect the data pertaining to internet usage among the residents of France with the help of modified internet addiction test tool, which is originally developed by Widyanto et al. (2011). For the original tool which has three constructs: Emotional Management, Time Management and Mood Management, an additional factor Culture is added. Because of the study limitations, data is collected from 122 respondents only. After validation, the data is analyzed using the statistical techniques in three stages - chi-square test, binary logistic regression and principal component analysis. The results are tested for 5% level of significance using latest statistical packages. The outputs of the analysis provided interesting insights. It is proved from the analysis that age has more bearing on the level of internet addiction. Yet, subtle factors are playing a role in providing a vague picture about the influence of constructs on internet usage and addiction. During first stage of analysis, the effect of emotional management is not present, during second stage effect of time management is not evident and in third stage of analysis, except the effect of emotional management index no other effect of constructs is found on the internet usage pattern. These differences could be because of the smaller size of the sample which is not a good representative of the various groups of people in France. So, studies planned by ruling out these issues can result in accurate data with minimal variation and hence better results about internet usage as well as internet addiction.

Mobile Banking Acceptance by the Customers in Iranian Banks
by Seyed Hossain Siadat, Lotfollah Najjar
Abstract: In this research mobile banking acceptance is studied among Iranian banks from the consumers point of view. To investigate attitude towards use of mobile banking, attitude variables are studied including ease of use, effectiveness, cost, risk, credit, trust, compatibility with style, demographic characteristics, social influences, self-efficacy and satisfaction. Therefore, this study builds a comprehensive conceptual model consisting of both attitude and demographic factors. We collected 385 samples from five cities of Iran: Tehran, Mashhad, Bandar-Abbas, Babol and Khorram-Aabad, in the form of electronic and printed questionnaires. The research confirmed all primary assumptions with respect to attitude variables. According to the results, the proposed variables can effectively clarify the acceptance of mobile banking among Iranian customers. Regarding demographic characteristics, effect of gender on mobile banking acceptance is proven, but the effects of age, education and monthly income on mobile banking acceptance are not proven. Compatibility with life style and satisfaction were found to have the highest coefficient correlation among other variables.
Keywords: Mobile Banking; Adoption; Mobile Banking Acceptance; Attitude; Demographic Characteristics.

The Online Educational Model and Drivers for Online Learning
by Efosa Idemudia, Ogechi Adeola, Nubi Achebo
Abstract: The rapid and constant growth of technology, hardware, and software have greatly influenced and improved online education. Universities all over the world are investing huge sums of money in online courses and degree programs. Some universities are offering these programs at all levels of study from baccaulaureate to doctoral. Given the increasing importance of online learning, stakeholders interests must be considered in designing effective learning environments to improve the acceptance of these programs, to lower their drop-out rates, and to motivate students to complete their studies. To our knowledge, there are no studies that have directly applied the stakeholder theory to online education. To address this issue and contribute to the literature, we developed an online educational model that provides insights and understanding on how to improve and develop online education. The theoretical background for our online educational model is the stakeholder theory. The theoretical and practical implications of our research are discussed.

A Rationale for the Choice of Enterprise Architecture Method and Software Technology in a Software Driven Enterprise
by Venkatesan Devanathan, Sridhar Sundaramoorthy
Abstract: Enterprise architecture frameworks (EAFs) provide tools and methods to categorize, document and depict interrelationship between enterprise business processes, stakeholders and information classes. It explicitly documents information generation, processing and consumption pattern facilitating communication and management. But there is a confusing variety of EAFs for organizations to choose from. There is no explicit guidance or justifiable rationale available to choose an EAF over others. This paper provides a rationale and attributes based evaluation of popular EAFs and conclude superiority of Zachman Framework (ZF) for an software-driven enterprise (SDE). Further this paper surveys salient aspects of different software technologies and provide an assessment framework to compare them and conclude suitability of agent technology for realizing information system infrastructure of an SDE. This work makes a provocative argument that many of the modern EAFs are not suited for an SDE due to their affiliation to software technologies that are found to has several limitations.

Hierarchically distributed Peer-to-Peer architecture for load balancing and effective dynamic group scheduling in Grid computing
by S. Gomathi Mathi, D. Manimegalai Megalai
Abstract: The Local or remote grid computing resources have been normally assigned the task of executing user jobs in a distributed environment. An important factor affecting Grid processing is the network bandwidth that differs from network to network. In order to overcome this problem, a few typical algorithms are suggested keeping in view of computing grid resources based on load balancing across the grid system. These algorithms help in improving the performance to some extent, yet none of them has been found experimentally suitable to overcome the major short falls experienced in the grid computing system. We propose a Hierarchically Distributed Peer-to-Peer (HDP2P) architecture to overcome all major problems encountered due to virtuality and heterogeneity. Results suggested that Hierarchically Distributed Peer-to-Peer (HDP2P) architecture was of great use in balancing the load and allocating to the resources to the groups of jobs keeping MIPS accountability using Grouping Based Dynamic Job Scheduling algorithm (GBDJS). Our proposed algorithm is compared with First Come First Served Job Scheduling algorithm (FCFS) and Ant Colony Optimization Job Scheduling algorithm(ACO).There is a considerable improvement achieved in performance by using this novel architecture

Leveraging Business Competitiveness by Adopting Cloud Computing in Indonesian Creative Industries
by Yudi Fernando, Syarif Achmad, Anderes Gui
Abstract: The purpose of this study is to identify determinants of the cloud computing adoption in creative industries in Indonesia, and the impact of that adoption on business competitiveness. A theoretical model was developed based on the two complementary models, the Technology Adoption Model (TAM) and Technology-Organization-Environment (TOE). An e-survey was conducted among firms that had adopted cloud-computing technology in Indonesia creative industries. This study provides sufficient statistical evidence to infer that perceived usefulness, compatibility, security and privacy, management support and competitive pressure were related to the adoption of cloud computing. Cloud vendors must consider incorporating networks that offer more user friendly and affordable solutions to the market. One factor related user friendliness is that the network must be convenient to use without any issues related to performance. Solutions tied to the cloud should be cost effective for small and medium-sized businesses.

Hybridising Neural Network and Pattern Matching under Dynamic Time Warping for Time Series Prediction
by Thanh Son Nguyen
Abstract: Pattern matching-based forecasting models are attractive due to their simplicity and the ability to predict complex nonlinear behaviours. Euclidean measure is the most commonly used metric for pattern matching in time series. However, its weakness is that it is sensitive to distortion in time axis; so, this can influence on forecasting results. The dynamic time warping (DTW) measure is introduced as a solution to the weakness of Euclidean distance metric. In addition, artificial neural networks (ANNs) have been widely used in the time series forecasting. They have been used to capture the complex relationships with a variety of patterns. In this work, we propose an improved hybrid method which is an affine combination of neural network model and DTW-based pattern matching model for time series prediction. This method can take full advantage of the individual strengths of the two models to create a more effective approach for time series prediction. Experimental results show that our proposed method outperforms neural network model and DTW-based pattern matching method used separately in time series prediction.
Keywords: time series; pattern matching; artificial neural network; time series prediction; dynamic time warping; k-nearest neighbour.

by Saba Hosseinisani
Abstract: The aim of this study is to identify and prioritize the Knowledge Management (KM) adoption in financial institutions. It helps organizations to concentrate on high rank solutions and develop strategies to implement them on priority. This paper proposes a framework based on fuzzy analytical hierarchy process (FAHP) and fuzzy TOPSIS to identify and rank the KM adoption financial institutions. In this paper, financial institutions (Melal financial and credit institute, Noor financial and credit institute, Kosar financial and credit institute) have been prioritized regarding the level, the knowledge management adoption sub-criteria and quintuplet solutions of Knowledge Management adoption scopes (Human Resources, Cultural factors, Organizational management, Technological factors). Results show that Melal financial and credit institute Kosar financial and credit institute and Noor financial and credit institute are on the first, second and last priority, respectively. The results obtained from fuzzy AHP methods indicate that Human Resources are on the first priority and Organizational management, Technological factors and Cultural factors are on the next priority. Then regarding to the Organizational management scales, it is realized that, proper organizational structure to create and share knowledge is most important. Regarding to the Technological factors index, it is realized that, technological infrastructure to adopt KM is most important. Regarding to Cultural factors index it is realized that, willingness and sharing spirit among members is most important. Regarding to the Human Resources index, it is realized that, time to share knowledge is most important.

Supporting BPMN Tool Developers Through Meta-algorithms
by Carlos Habekost, Lucinéia Thom, Erika Cota, Marcelo Fantinato
Abstract: Business Process Model and Notation (BPMN) provides an extensive set of notational elements, such as activities, events and gateways, which enable the representation of a wide variety of business processes. The purpose of this paper is to propose an approach to develop logical models (referred here as "meta-algorithms"), whose goal is to express the content described in the textual rules, for each BPMN element, considering the BPMN 2.0.2 specification. We identified that there is completeness and correctness in this approach, applying decision tables and control-flow graphs to checking the proposed meta-algorithms. Beside this, the authors applied two surveys, considering a potential audience for the proposed meta-algorithms in order to check users' acceptance. For validation results, we identified that only textual rules is not enough to implement the notational elements for 84% of the survey participants.

A User Study on Trust Perception in Persuasive Technology
by Wan Nooraishya Wan Ahmad, Nazlena Mohamad Ali
Abstract: A wide range of persuasive technologies has been developed for many different issues to assist people in changing their attitude or behavior. However, whether or not users trust persuasive technology and which trust perception affects them more in making trust decision are yet to be found out. Therefore, this study aimed to examine users trust level and its trust perceptions using two types of persuasive technologies, for example, health application and educational games on the environmental issues. The questionnaire is used as an instrument to measure trust level and trust perceptions. A pre-and-post-test approach is used to study 25 participants who are required to use both types of persuasive technology concurrently for 6 weeks. The finding shows that the users trust is at low-level, indicating a significant lack of trust problem. Cognitive trust dominates the trust decision-making though it is correlated with affective trust.
Keywords: trust; cognitive; affective; persuasive technology.
E-Collaborative Learning experience, Interdependencies of Presences and Learning Outcomes: Evidence of Mediating and Moderating Effects
by Alimatu-Saadia Yussiff, Wan Fatimah Wan Ahmad, Emy Elyanee Mustapha
Abstract: E-collaborative teaching and learning have gained much attention from practitioners, businesses and academics. However, the impact of e-collaborative teaching and learning on students learning outcomes with the mediating and moderating effects of three presences (social, cognitive and teaching presences) has not been thoroughly investigated. To bridge this gap, we conducted an experimental research design consisting of two main groups experimental and control groups. The control group, consisting of 42 students is the group using the conventional methods of in-class collaboration. The experimental group, consisting of 60 students used a developed e-collaboration system after which a survey was conducted using four sets of instruments the Community of Inquiry Survey Instrument, effectiveness for teamwork survey, pre-test and post-test questions. Partial least square approach to structural equation modeling was employed to analyze the experimental groups data based on the hypothesized relationship model. The results demonstrated that the constructs in the hypothesized model are reliable and valid. In addition, findings also indicated that e-collaborative learning experience strongly predict learning outcomes indirectly through the mediating and moderating effects of the three presences. This research offers significant contributions to practice, research and theory.

Mobile Decision Support System with Dynamic Knowledge Base using Decision Tree and Case-Based Reasoning
by Hasimah Hj Mohamed, Muhammad Rafie Hj Mohd Arshad, Muhammad Dzulhimi Azmi
Abstract: Muslims from around the world performing Hajj and Umrah every year. The rituals involve many rules and procedures in which can become a challenge for pilgrims to remember. While performing the ritual, pilgrims might encounter some problems that need an immediate solution, especially those related to dos and donts in the ihram. The best way to get the solution is by referring to the ustaz or muttawif (Hajj Guider). However, theyre limited and not available all the time. It is best to have a knowledge that can be stored digitally that enable the pilgrims to refer it anytime and anywhere. We proposed a dynamic knowledge-based approach that can capture possible problems and solutions from the expert on mobile platform. Users can query both simple and advance questions to the system. The system is on android and web based platform. The system has been implemented using an artificial intelligence method of Decision Tree and Case Based Reasoning methodology. We use case based reasoning to retrieve similar cases (Question and Answer). Decision tree with dynamic knowledge based is being used to predict the solutions for problems inquired by users. Rules are stored in databases, and it will be retrieved according to the problems given. We have implemented these methods on hajj domain to solve the dumm imposition for the ihram ritual which can be referred by pilgrims anywhere and anytime to solve any problems encounter during hajj ritual.

An investigation of factors influencing the intention to use mHealth apps for self-care
by Faiz Aiman Azhar, Jaspaljeet Singh Dhillon
Abstract: This paper reports factors that are essential to be considered in the design mHealth apps for self-care. Self-care is an emerging area that refers any intentional actions people take to care for their physical, mental and emotional health. Encouraging people to practice self-care is a challenge and it is known to be an important part of a healing process. There are numerous health support applications in the market that can be downloaded via smartphones. These apps are typically designed to enable healthcare consumers to improve their health or maintain their good health. However, recent research indicates that with the exception of physical activity, more consumers are currently tracking key health factors on paper or in their heads than with mobile applications. In this paper, we identify factors that influence the intention to use mHealth apps for self-care that were identified via a systematic literature review approach and which thereafter were investigated quantitatively by involving 203 consumers. These factors when considered in the design of future mHealth apps could address the requirements and expectation of consumers towards mHealth apps in general and could possibly motivate them to use mHealth continuously in achieving their health goals.

by Neesha Jothi, Nur'Aini Abdul Rashid, Wahidah Husain, Lee Ker Xin
Abstract: Mental health presents as one of the greatest challenges to the current generation. It has been reported that about 5% of the population in developed countries are affected by Generalized Anxiety Disorder (GAD) withwomen twice as likely to be affected as compared to men. Predicting GAD among women is no longer an arduous task especially with the assistance of data mining technology. In this paper, a methodology encompassing data collection, data preprocessing, data analysis and data mining process using random forest approach is drawn for an effective prediction. The random forest approach is one of the classification data mining techniques which is embedded with good predictive characteristic. The result of this study in term of accuracy, sensitivity and specificity conforming to its high predictive performance in GAD prediction based on depressive symptoms. Besides that, several popular machine learning techniques are also applied to the resultant dataset of this study and the comparison result attests to random forest algorithm outperformed other methods. The generated prediction model is expected to provide an effective screening process to detect Generalized Anxiety Disorder earlier among women in Malaysia.

by Deborah Paris, Mahadi Bahari, Noorminshah A. Iahad
Abstract: Despite various studies conducted on the implementation of business-to-customer (B2C) e-commerce, prior studies presumed that B2C e-commerce implementation as a plug and play exercise rather than a process-based. This paper presents a model for the implementation process of B2C e-commerce in a fashion and apparel business. Based on qualitative research approach using a case study and summary of experience, a model for the implementation process of B2C e-commerce is proposed. The model describes the characteristics of 14 implementation factors that occurred during Lewins and Kotters stages of implementation. Although the models generalisability is limited, it offers a guideline for the existing and future senior managers of B2C e-commerce in fashion and apparel business. This model helps managers to identify the highlights in each stage of the B2C e-commerce implementation process.

Validation of a Multimodal Interaction Model for Foot Reflexology Virtual Reality Stress Therapy Application
by Suziah Sulaiman, Hector Chimeremeze Okere, Dayang Rohaya Awang Rambli, Oi-Mean Foong
Abstract: Multimodal interactivity when supported in a foot reflexology virtual reality environment has the potential to relief stress. Current works leading to the development of such an environment have focused on creating models involving human to human (H-to-H) interactions which later could be used as design requirements. The goal is to translate these requirements and lay foundation for future foot reflexology virtual reality stress therapy (VRST) application. Despite the intention, the development missed an important activity that is feedback from those experts in the domain. This paper closes the gap by presenting an expert review to the multimodal H-to-H interaction model as a form of validation. Eight experts from the Human Computer Interaction (HCI) domain or related field reviewed and provided feedback on the model. The reviews were utilized to reconstruct the multimodal H-to-H interaction model, consequently yielding a final validated model for foot reflexology VRST application.
