S Adaptive Web Service Composition Based on Interface

Web services have received much interest due to their potential to design and build complex inter-enterprise business applications. A particular interest concerns dynamic Web services composition that offers the opportunity for creating new Web services at runtime from those already published. In this paper we focus on mismatches occurring during dynamic composition of Web services. These mismatches require adaptation to insure the correct working of the involved components in the service composition. We propose an approach for dynamic and automatic composition and adaptation of Web services. The approach is based on the information that is already available in interface descriptions. The approach allows programmers to define dynamic Web service composition and adaptation without changing the source code.
