Composing Web services on the Semantic Web

摘要: Service composition is gaining momentum as the potential silver bullet for envisioned Semantic Web. It purports to take Web unexplored efficiencies and provide a flexible approach promoting all types of activities in tomorrow’s Applications expected heavily advantage service include B2B E-commerce E-government. To date, enabling composite services has largely been an ad hoc, time-consuming, error-prone process involving repetitive low-level programming. In this paper, we propose ontology-based framework automatic services. We present technique generate from high-level declarative descriptions. define formal safeguards meaningful through use composability rules. These rules compare syntactic semantic features determine whether two are composable. implementation using E-government application offering customized indigent citizens. Finally, exhaustive performance experiment assess scalability our approach.
