Ranked Web Service Matching for Service Description Using OWL-S

The Web-services stack of standards is designed to support the reuse and interoperation of software components on the Web. Semantic Web services envision the automated discovery and selection of Web services. The discovery and selection process finds matches between requirements and advertisements according to their semantic description. There are already some approaches available for matching of service requirements with service advertisements. We propose a ranked approach of Web service matching that complements logic based reasoning with approximate matching, which ranks the matching degree of service descriptions according to OWL-S. Our service matching method is based on Latent Semantic Indexing and a logic based reasoning. Contrary to mechanisms that return only success or fail, ranked results provide criteria for the selection of a service among a large set of results.
