Abstract: To perform an arbitrary service composition task in a graph database, and to support plug-in semantic matching of services, we present a novel service composition approach in a graph database named pre-joined service network. Firstly, the proposed approach constructs and stores a composition network with all services and compositions in a graph database. Then, it fetches a satisfying solution by converting the user's request into queries in the graph database. To illustrate the process of searching for a solution, a simple but meaningful example is provided. Furthermore, we test the performance of the proposed approach with a challenge dataset. Experiment results show that the proposed approach can always find a valid solution and lead to higher user satisfaction when compared with the pre-joined semantic indexing graph approach.
