Discovering Web Services Based on Functional Semantics

With the rapid development of Web services technologies, discovering Web services is becoming the most urgent problem to be resolved. The existing Web service discovery methods are not mature, and cannot cope with the requests from different fields very well. In this paper we suggest an effective and feasible approach of Web service discovery based on functional semantics. We define Web services functional semantic description that provides a unified manner to semantically describe the function of Web service for service providers and customers. In order to avoid semantic heterogeneity, we build domain-oriented functional ontology and propose semantic annotation mechanism. Then we describe the matching algorithm. Finally we evaluate the performance of our algorithm by an experimental setup. The results of the experiment prove that our approach is feasible and effective
