Abstract: Now in the grid system based on open grid service architecture, grid services are discovered by keywords, which make the match inflexible, sometimes even unfaithful. This paper puts forward a method that can match services semantically by applying OWL-S to represent grid services and a grid service semantic repository to store all distributed services’ ability. When matching goes on, the ontology repository provides domain knowledge which is organized in tree-model for high match efficiency to complete the semantic match. And in order to make the matched services invoked correctly, a UDDI register center is used in the method to store the counterpart register information which is described by WSDL. The paper analyses the feasibility of the method.

摘要： 针对目前网格系统中，将名字作为关键字对服务进行查找存在的不准确、不灵活的缺陷，提出了一种网格服务的语义匹配方法，在该方法中，用OWL-S对网格服务进行语义上的描述，用UDDI来进行服务的注册和发现，用一个语义服务库存储虚拟组织中所有发布的网格服务功能的语义信息，这个语义服务库对每个领域的服务用树的形式进行组织。通过建立领域本体库为服务功能语义上的匹配提供知识支持。对方法进行了可行性分析。
