为了解决语义Web服务匹配方法主要针对服务IO描述的匹配,导致匹配结果较为片面的问题,提出了一种基于描述逻辑的语义Web服务IOPE描述及匹配方法.具体使用描述逻辑概念标注服务IO,以描述逻辑断言库刻画服务PE.进行服务匹配时,利用描述逻辑TBox概念包含检测确定服务请求与广告IO之间的包含关系;利用描述逻辑ABox一致性检测推理,判断服务请求与广告PE之间的逻辑蕴含关系;依据此蕴含关系,将PE匹配情况划分为4种,即Exact,Perfect, Side-effect和Common匹配,用以对匹配结果进行有意义的排序.实验结果表明,所提方法在召回率与现有方法相当的情况下,具有更高的查准率.
In order to solve the problem that the semantic Web service matching method mainly matches the description of service IO and leads to a more unoptimized matching result, a semantic Web service IOPE description and matching method based on description logic is proposed. Specifically, the description of service IOPE Describe the logic assertion library description service PE. When performing service matching, use the description logic TBox concept inclusion detection to determine the inclusion relationship between the service request and the advertisement IO; and use the description logic ABox consistency detection reasoning to determine whether the service request and the advertisement PE According to the implication, PE matching is divided into four kinds, that is, Exact, Perfect, Side-effect and Common, which are used to sort the matching results in a meaningful way.The experimental results show that the proposed method With the same rate as the current method, it has higher accuracy.
