Study on Semantic Web Services Discovery with QoS Constraint
Chun Li · 2007
Traditional Web services only provide simple classification and keywords-based methods based on UDDI technical specification mainly, lead to low precision and recall, compatibility is influenced of service reuse and composition. Web services with semantics also always set focus on function matching, thorough matching and quick location are guaranteed difficulty without quality of service and vivid , efficiency matching method. In this paper, existing related researches are analyzed, on Web service model, combine the thought ofapproach gradually, a kind of matching and filter algorithm with three level is presented, each of algorithm, namely basic description, IOPE and QoS matching is thoroughly discussed, similarity functions is introduced to measure Web service similarity degree of provider and requester, this approach will be significant to Web services discovery.
