摘要
现有的网格资源匹配方法是把对资源的描述和约束进行精确的语法匹配,其灵活性差,难于扩展新的概念或特征.引入语义网中本体的概念,利用本体进行网格资源匹配,按照资源匹配的要求,构建网格需求方与提供方共享的网格资源本体,通过本体、背景知识和匹配规则进行语义匹配,进而获得满足需求的资源.
Existing resource matching in grid is to match the description of the resources and restraints. The exact syntax matching is inflexible and difficult to extend to new concepts or characteristics. In this article,the concept of ontology in semantic web is used to match resources in the grid. According to requirements of resource matching, the resource ontologies shared by consumers and are established. Ontologies, background knowledges and rules are matched with semantics to meet the demand of accessing resources.
