Abstract: Describing the Web service using domain ontology and matching Web service on the semantic level is a hot research spot. After analyzing the disadvantage of traditional approach for semantic matching, an improved matching algorithm which adopts semantic distance and match coefficient is proposed. A prototype system based on this method is implemented. Experimental results show that this algorithm can improve the precision of match degree of service.

Key words: semantic Web service, ontology, service matching

摘要： 引用领域本体对Web服务进行语义描述，再进行语义层上的匹配，是Web服务匹配研究领域的重要研究方向。针对传统匹配算法在语义Web服务发现中的不足，采用语义距离、匹配度系数等对其进行扩展，在此基础上实现一个原型系统。实验表明，该算法能提高Web服务的匹配精度。
