【摘要】 为了提高Web服务匹配的效率和灵活性,提出了一种基于语义的Web服务混合匹配方法。该方法首先扩展了服务的功能描述模型,并基于该扩展模型进行混合服务匹配。混合匹配方法联合使用了两种匹配策略:基于推理的匹配策略,通过本体概念的逻辑关系实现匹配;基于相似性计算的策略,通过本体概念间相似度计算进行服务的匹配。在服务匹配过程中,首先使用基于推理的匹配策略将服务分成4个匹配等级,然后,采用基于相似性计算的匹配策略对候选服务进行进一步地匹配。实验结果表明该方法是可行而有效的。更多还原

【Abstract】 In order to improve the efficiency and precision of Web service matchmaking,the paper presents a hybrid matching method based on semantics.The method extends the Web services functional description model,upon which hybrid matchmaking is carried out.The proposed hybrid method combines two matching strategies:A deductive strategy based on logical relationship between ontology concepts and a similarity-based strategy based on similarity computations between ontology concepts.During the matchmaking process,the deductive strategy is firstly used to distinguish candidate services into four matching types.Then,the similarity-based strategy is used to further match among the candidates.Experiment results show that the proposed method is feasible and effective.更多还原
