Abstract: Ontologies play an important role in applications related to knowledge management, natural language processing, information retrieval, etc. As a result, a large number of ontologies have been developed rapidly. Once an ontology is created, it can be used by many different applications. Such applications may use the entire ontology or only a part of it. Furthermore, they may use a part of the ontology and then extend it by adding more knowledge. Since ontologies which are used by different organisations may be related, there is a need to check these relationships. This paper presents an algorithm that compares two ontologies to determine their relationship. A semantic web service discovery application is introduced to highlight the motivation of the algorithm.

Keywords: ontology comparison; semantic web; web services; web service discovery; ontologies.
