Keyword matching is a traditional method of web service. However, by the method it is very difficult to find out the potential semantics contained in web service. Therefore, more and more scholars are studying how to query the web service based on semantics. This paper proposes a new semantic matching mode based on the ontology service indexing. By building an indexing from service to ontology, the service and ontology can be regarded as a logic entity. The requests from users are sent to the rule base directly by UDDI, and then reasoning rules can be used to get classes and instances of ontology in a proper range. Finally, the result set is inputted into the ontology service indexing, with which the user could get a better web service result set via the matching.%传统的获取Web服务的方法是通过学者研究如何基于语义检索Web服务.本文设计了一种新的语义匹配模式:基于本体服务索引的服务匹配.通过建立从服务到本体库的索引,将本体库和Web服务库关联成一个逻辑整体.通过UDDl,用户请求会直接发送给推理规则库,在得到服务请求后,通过相应推理规则得到领域本体中与服务请求在一定相似度范围内的类及实例,而后将这个结果集输入到本体服务索引,经过匹配可输出较符合的Web服务结果集.
