摘　　要：为提高服务组合中服务匹配速度和正确率,提出了基于服务索引的服务语义匹配机制。在面向独立服务匹配算法基础上,引入服务索引机制,提出面向服务组合的语义匹配算法,并在算法中加入了对服务输入/输出匹配的可用性分析。为进一步提高服务匹配的精确性,引入了语义匹配度概念,以实现具有多种匹配值的服务类别语义匹配,继而给出综合语义匹配值的计算方法。实验分析表明基于服务索引的语义匹配能有效地提高服务匹配效率。To improve the speed and correctness of Web service matching for services composition process, a semantic matching mechanism is proposed with the help of services indexes. Based on indexes mechanism and services semantic matching algorithm for single service, a composition-oriented services semantic matching algorithm is proposed and the matching usability of service input/output is analyzed. To improve the accuracy of service matching, the semantic matching degree for services category matching is introduced, and then the computation method of overall semantic matching is provided. Experimental results show that this composition-oriented service semantic matching can enhance the efficiency of services matching based on services index.
