Rebuilding the Semantic Web Service Architecture

Abstract: Semantic Web services can be defined as “the augmentation of Web Service descriptions through Semantic Web annotations, to facilitate the higher automation of service discovery, composition, invocation, and monitoring in an open, unregulated, and often chaotic environment ” (Payne, et al., 2004). Web service infrastructure (WSDL, UDDI and SOAP) has been criticized in almost all papers on the topic of “Semantic Web Services”, typically as “existing technologies for Web services only provide descriptions at the syntactic level, making it difficult for requesters and providers to interpret or represent non-trivial statements such as the meaning of inputs and outputs or applicable constraints ” (Cabral, et al., 2004). Adding rich semantics into Web Services are expected to “support greater automation of service selection and invocation, automated translation of message content between heterogeneous interoperating services, automated or semi-automated approaches to service composition, and more comprehensive approaches to service monitoring and recovery from failure ” (Martin, D., et al., 2004). Current approaches for Semantic Web Service infrastructures are developed by a variety of research groups, among those efforts, OWL-S (Martin, D., et al., 2004), WSMO (Roman, et al., 2004), etc. were the most recognized and outstanding achievement to date in this field. However, how to derive service semantics automatically has been problematic with the current syntactically oriented Web services technologies. This paper proposes a fundamentally different approach to rebuild the semantic Web Services architecture. The semantic web service generated by this proposed new approach is
