基于消息语义相似度二分匹配的Web服务发现方法

随着Web服务数量的剧增，Web服务发现是目前面向服务的体系架构中的重要部分。并且成为Web服务研究的一个热点．笔者提出了一个基于语义匹配的服务发现方法．首先，在标准WSDL中进行本体相关的语义扩充，将服务操作中必要的信息进行语义映射，包括：Web服务操作名称以及服务操作的输入消息和输出消息．其次提出了一个基于消息语义相似度二分匹配的Web服务发现方法．实验表明该方法提高了服务发现的查全率和查准率，且具有良好的可伸缩性．最后得出结论：该方法使用WSDL标准规范而不是特定的Web服务语言或模型，因而易于实施；该方法提高了计算机自动发现服务的效率．

Web service discovery based on bipartite matching of message semantic similarity

With the increasing growth in number of Web Services, Web Services discovery is currently a central task in service-oriented architectures and becomes a hot topic in Web Services research. This paper presents a discovery method with sophisticated semantic matchmaking. At first, we extend WSDL by adding ontology related semantics which are mapped to necessary operation interfaces of Web Services, such as operation names, input messages and output messages. Then, a method of service discovery based on bipartite matching of message semantic similarity is proposed. And experiments illustrate the method improves its efficiency much, and gets fine scalability. It is concluded that the method is easy to implement because of using WSDL standard while not other specific service languages or models. And it contributes to the improvement of service discovery efficiency when discovery is automated.
