一种基于关联匹配度计算的语义Web服务匹配方法

在现有的语义Web服务匹配方法基础上加入服务语义关联匹配度计算,从而提出一种改进的语义服务匹配方法。该方法通过语义关联将一对一匹配淘汰的服务进行组合来实现一对多的服务匹配,在得到的候选服务和候选服务集中进一步计算Web服务的匹配度,经过匹配度的排序,得到最佳匹配度的服务。该方法避免了仅从单一接口参数上进行语义服务匹配,能在一定程度上提高匹配的效率,实现查准率、查全率和查询效率之间的有效平衡。

A Matching Method for Semantic Web Services Based on Association Matching Degree Calculation

An improved semantic Web services matching method is proposed,which introduces the calculation of association matching degree into the existing common service matching process.It uses the semantic association to realize the one to multiple matchings through composing the one to one matchings eliminated services.Further,the calculation of association matching degree of services is performed on the candidate services set.Then the best matched service is obtained by ordering the matching degree.It can avoid the shortcomings of service matching on parameters from single interface and be helpful for improving the effect of matching as well as the tradeoff among the precision rate,recall and query efficiency at certain extent.
