Flexible web service composition based on interface matching

Abstract

Composition of Web services has received much interest in the field of business-to-business or enterprise application integration. In our work, we propose a composition method based on service interface matching. Compared to previous work, our approach only uses the information that is already available in service interface definitions. It does not require that service providers describe their interfaces with semantic markup. We propose data type matching and service composition algorithm. The similarity score calculated by our algorithm allows for flexible Web service composition. Users can define different score threshold for either relaxed or accurate service composition. The experimental results show that the matching algorithm has good precision and recall. © Springer-Verlag 2004.
