Effective Web Service Discovery Based on Functional Semantics

Web service discovery is a mechanism which facilitates an access to the Web service descriptions. UDDI facilitates the discovery based on the service functionality through keyword and category matching. Such discovery techniques do not consider the semantics and user context as they are too syntactic in nature. In this paper, we propose a well formed functional semantics to describe an operation of a Web service. We design the extendible functional knowledge to map the requested or published operation descriptions into an abstract operation. The experimentation shows that, the proposed functional semantics based discovery mechanism has better performance in terms of precision and recall.
