Abstract—Semantic information, which is well-regulated and easy to be retrieved, has greatly enriched the expressive ability of the Web. These advantages can be applied in Web Services to meet the increasing complexity of Web applications. In this paper, we propose a service composition approach. It combines the large-scaled Web Services and semantic information which is described in WSC’09. Besides, QoS has become a critical issue to evaluate the performance of Web applications. Being different from improving the QoS of single services, our approach focuses on the overall QoS of the service composition. The algorithm shows that the semantic information based and QoS driven approach improves the efficiency and QoS performance of service com...
