Semantic Web-Service Discovery and Composition Using Flexible Parameter Matching

When there are a large number of web services available and no single service satisfies the given request, one has to compose multiple web services to fulfill the goal, considering syntactic and semantic aspects. To address the web service composition issue, in this paper, we present a new composition algorithm by extending our previous work, WSRP (web-service planner) so as to determine relations between different parameter types during the process of service composition.
