语义信息规范、易检索，极大地丰富了Web的表达能力。这些优势可以应用到Web服务中，以满足日益复杂的Web应用程序。本文提出了一种服务组合方法。它结合了大规模的Web服务和WSC‘09中描述的语义信息。此外，服务质量已经成为衡量Web应用性能的一个关键问题。与提高单个服务的服务质量不同，我们的方法着眼于服务组合的整体服务质量。该算法表明，基于语义信息和服务质量驱动的服务组合方法提高了服务组合的效率和服务质量。
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 composition.
