Adding semantics to web services standards

With the increasing growth in popularity of Web services, discovery of relevant Web services becomes a significant challenge. One approach is to develop semantic Web services where by the Web Services are annotated based on shared ontologies, and use these annotations for semantics-based discovery of relevant Web Services. We discuss one such approach that involves adding semantics to WSDL using DAML+OIL ontologies. Our approach also uses UDDI to store these semantic annotations and search for Web services based on them. We compare our approach with another initiative to add semantics to support Web service discovery, and show that our approach may fit current standards-based industry approach better
