针对目前语义Web服务匹配方法中缺少对服务行为约束的考虑及传统推理匹配的结果中同一级别不能再区分的缺点,本文设计了一种带行为约束的基于推理和语义相似度计算的匹配方法。本方法分为三步:第一步进行服务行为约束兼容性检测;第二步对待匹配的两个服务进行推理;第三步在第二步基础上进行本体概念间的语义相似度计算,得出最终的精确的匹配度。实验结果表明,该方法较之传统的OWL-S/UDDI匹配方法在查准率和查全率方面得到了很大改进。
In view of the lack of consideration of service behavior constraints in current semantic Web service matching methods and the fact that the same level of traditional reasoning matching can no longer be distinguished, a matching method based on reasoning and semantic similarity calculation with behavior constraints is designed. The method is divided into three steps: the first step is to conduct service behavior constraint compatibility detection; the second step to treat the two services that match; the third step is to calculate the semantic similarity between ontology concepts based on the second step The final precise match. The experimental results show that the proposed method has greatly improved the precision and recall ratio compared with the traditional OWL-S / UDDI matching method.
