Abstract
Service oriented architecture is a challenging area to fervently focus on. In that web service composition plays a vital role. The main crux behind composition lies on the effective selection of available web services in order to provide the value added services on the fly. Quality of Service (QoS) is one of the non functional properties of the web services, which is used to evaluate the degree to which the service can satisfy the service request. In the proposed approach, the composition is handled based on the QoS the web service has provided in its previous attempts towards composition. A separate process of updating the beliefs and reputation is been identified which stores the appropriate belief factor against the candidate web service in the process registry. Instead of having the QoS as a constant provider specified value, our approach assigns the value based on the end users feedback. The paper discusses the approach used in identifying the quality of the web service composition and the efficiency of composing relevant services for the service request.
