摘　　要：由于网格具有动态异构等特点,传统的基于属性的精确匹配方法不够灵活,并且扩展性差.将本体论的思想和方法引入到网格服务集成环境中,建立了基于本体的网格服务匹配系统结构,分析了基于语义上下文的领域匹配算法和领域内的服务匹配算法,从而实现了一种应用本体、基于语义的服务匹配机制.实验结果表明,提出的算法具有可接受的服务匹配时间、较高的匹配成功率和较强的获取网格服务的能力.Because of the dynamic and heterogeneous characteristic of grid, traditional matchmaking which was based on exactly attributes matching leads to low flexibility and bad extension. The idea and method of ontology were introdued to the integration system of grid service. Based on Ontology , system framework of grid service matching was built. Context-based domain matching algorithm and Ontology-based service matching algorithm were analyzed. A service matching mechaniam of ontology and semantic was realized. The result of experimentation indicate that the service matching time is acceptable ,and more successful efficiency and ability of taking grid service can be achieved.
