Research on Converged Service Composition Based on Extending CSTA Services with OWL-S

Automatic service composition converging these two services in telecom and Web realm can hardly achieved by far inasmuch as the absent semantic services interface defined with WSDL. In this paper, after analyzing the shortcoming of these existing description technologies of Web services and telecommunication services, we put forward an extending method via enriching the content of OWL-S Profile document with OWL-S to CSTA services specified in ECMA specifications, and an improved algorithm of forward chaining automatic service composition to facilitate the converged service composition between network services and telecommunication services. The proposed technique is applied to an automatic stock quote scenario and composition results are presented demonstrating the rationality of these proposed ideas.
