A New Web Service Discovery Model Based On QoS

Web service technology is playing a major role in today´s distributed system computing, service discovery, i.e., the identification of existing WSs that can be used by new Web applications, is one of the most critical problems deterring Web service (WS) technology, current solution is based on UDDI catalogue browsing support only primitive matching mechanisms and provide no control over the quality of registered services. We aim to refine the discovery process through designing a new framework that enhance retrieval algorithms by combining syntactic, semantic matching of service and also support QoS information exploiting the environment knowledge form user experience of service invocation and service initial run tests results.
