Semantic Web service composition in IRS-III: the structured approach

Semantic Web services facilitate activities including automatic discovery and composition of Web services. Research initiatives such as WSMO have been developing specifications for this technology. This paper describes a model for composition of Web services. The proposed model complements the WSMO orchestration in IRS-III, a framework for semantic Web services based on WSMO specification. We present a tool based on the above model that supports a user-guided interactive composition approach, by recommending component Web services according to the composition context.
