摘要
针对Web服务组装过程中服务输入-输出接口连接程度量化和多分量连接对应关系判定问题,提出了一种新的连接度量化方法。该方法基于领域本体中的概念条件出现概率,将服务连接程度定义为输入-输出接口概念的替换可能性。在此基础上,利用二部图稳定匹配算法给出了服务接口各分量之间连接对应关系判定算法。最后讨论了不同连接样式下复合服务连接度计算,并分析算法的时间性能。
Aiming at connectivity computation and interfaces correspondence analysis in Web service connection, the concept subjective support and confidence definition is presented based on the concept＇s conditional appearance probability in domain ontology. And then the connective degree between two service interfaces is quantified. Furthermore, an adapted stable matching algorithm is introduced to solve the interfaces correspondence judgment. Finally the service connection is discussed in varied cases.
