摘要： 通过定义本体中概念之间的语义距离来计算本体概念之间的相似度，提出一种基于该相似度的Web服务的精确匹配算法，新的算法与经典的OWL-S/UDDI匹配算法比较，不仅在等级上保持一致，而且使同一等级或不同等级之间的服务匹配都达到精确的程度。用GEIS系统中Web服务的数据进行两种算法的性能测试，得出相似度匹配算法的平均查准率是OWL-S/UDDI匹配算法的1.8倍，平均查准率是OWL-S/UDDI匹配算法的1.4倍。

Abstract: A semantic distance between ontology concepts is defined to calculate the similarity between ontology concepts. Based on the similarity, a new semantic Web service matching algorithm is proposed. This algorithm abides by the grade of the classic OWL-S/UDDI algorithm and gives the precise matching between Web services. Experimental results show that the average precision of the new algorithm is 1.8 times than the OWL-S/UDDI algorithm and the average recall of the new algorithm is 1.4 times than the OWL-S/UDDI algorithm.
