为了能够在分布、动态、复杂的网格资源查找过程中做到高效率、高精度的匹配,该文对语义Web技术和匹配算法进行了改进。在本体描述方面,针对网格特性对OWL-S进行了扩充,引入了网格服务的语义表示形式,使得Agent可以参与进来。在基于语义的服务匹配方面,定义了服务发布和请求条件的领域限定并在领域内进行服务匹配,设计了一种基于语义的网格服务匹配框架,给出了该框架的结构图,并分析说明了其中关键部件的功能和特点。该框架的正确合理性经原型实现得到了证明。
In order to achieve efficient and accurate matching in distributed, dynamic and complex grid resource search, this paper improves on Semantic Web technology and matching algorithm. In terms of ontology description, OWL-S has been extended for grid features, and the semantic representation of grid services has been introduced so that Agent can participate. In the aspect of semantic-based service matching, the domain definition of service publishing and request conditions is defined and service matching is performed in the domain. A semantic-based grid service matching framework is designed, and the structure of the framework is given and analyzed Explain the functions and features of the key components. The correctness of the framework has been proven by prototype implementation.
