Semantic Based Web Services Discovery

摘要

This paper presents a novel approach for Web Services discovery on the envisioned Semantic Web. At first it proposes ontology based four-layer Web Services description model which is helpful for data-independence and concept-sharing. And then a users services preferences and constrains model upon the description is described. SBWSDF (Semantic Based Web Services Discovery Framework) is a framework to implement Web Services discovery using these models. Using the prototype of this framework, we set up a services ontology base and a rules base about flight booking. This prototype integrates the services description, the preferences and constrains rules and the request information to select proper services by using an inference engine. The result proves its a new approach of Web Services discovery with intelligence.
