An Requirement-Aware Approach for Composing Web Services

Web services adopt tasks to discovery, select and compose web services, but it has always been focused on business functions. Therefore, in this thesis, a novel requirement-aware approach for composing web service is proposed with respect to changes of users’ requirements which builds similarity of service requirements to satisfy dynamic restructuring of service composition, and employ membership function and semantic to assign similarity degree between service requirements and web services so that it can be mapped between semantic requirement and semantic web services by semantic relationship. We test the performance of the overall approach using a set of simulation experiments and demonstrate the effectiveness of our approach.
