摘要： 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。

Abstract: In order to match resources more efficiently, this paper puts forward some improvements of semantic Web technologies and matching algorithm. It extends OWL-S to suit grid ontology and introduces semantic description format for grid services so that agent technology can be involved. Domains of service registers and service requests are defined, and services matching is completed in the specific domain. It also presents a framework structure called grid services matching framework based on semantics (GSMFS), which includes services request, services register and services matching. Functions and characteristics of key components are illuminated. By prototype implementation of the framework, it is proved logical and right.

Key words: grid services, grid services matching, OWL-S, ontology
