现有的语义Web服务匹配算法没有考虑到本体概念间的多元关系,导致概念的语义不能被完整地反映出来,从而影响了算法的匹配性能.利用本体概念间的多元关系定义了一种语义距离,并通过该语义距离给出了概念间的语义相似度计算方法,在此基础上提出基于语义相似度的Web服务匹配算法.该算法通过本体概念间的语义相似度来反映web服务的匹配程度.最后,通过对比实验验证了该算法的可行性和有效性.%Existing semantic Web service matching algorithms take no account of pluralistic relations between ontology concepts, which disables the concept semantics to be completely reflected, so that the matching performance of the algorithms is degraded. Pluralistic relations between ontology concepts are used to define a kind of semantic distance, with which to put forward a method for computing semantic similarities among concepts. On this basis, a Web service matching algorithm based on semantic similarity is proposed. This algorithm reflects Web service matching degrees by calculating the semantic similarity among concepts. At last, the proposed algorithm is proved to be feasible and effective by a comparative experiment.
