摘　　要：【目的】更好地根据用户的需求在网格服务本体库中查询相对应的本体,进而找到对应的服务。【方法】把用户对服务的描述转化为网格服务描述本体,在IOPE算法的基础上通过分析服务功能的语义描述,逐级匹配从而实现匹配全过程的定量分析,改进现有服务本体的匹配算法。【结果】实现真正本体之间的匹配,即网格服务描述本体与存储在网格服务本体库中的网格服务本体之间的匹配,仿真实验证明这能够有效地提高网格服务本体匹配的准确率。【局限】改进的算法只在网格仿真平台上经过验证,并没有在更为复杂的网格环境中进行验证。【结论】改进的新算法可以实现匹配全过程的定量分析,从而有效地提高查准率。[Objective] In order to query the corresponding Ontology according to the user＇s demand better, and then find the corresponding service. [Methods] The authors transform the user＇s description of service to the Ontology in the grid service, and on the basis of lOPE algorithm, match the content step by step and realize the quantitative analysis of the whole process, that improve the matching algorithm of the existing service Ontology. [Results] Realize the match between the Ontology in the description of grid service and the Ontology which stored in the grid service repository. The simulation results show that it improves the accuracy of the grid service Ontology matching. [Limitations] The improved algorithm is validated in the simulation platform but can not be verified in the more complex grid environment. [Conclusions] The new algorithm can achieve the full match process of quantitative analysis, and effectively improves the precision.
