摘要： 采用语义网格技术实现GIS 信息共享。由于WSDL 文件只有服务的接口信息，当用户调用多个GIS 服务时，不能判断哪一个服务更符合要求。采用将WSDL 中加入语义功能，将用户的需求本体与WSDL 进行匹配的方法实现网格服务功能的查找。文中采用模式图作为WSDL 和OWL 的匹配中介，实现了本体与网格的结合。

Abstract: This paper uses semantic Web to implement sharing of GIS. Because WSDL only has interface of service, user can not choose which service fits him when there are several services. This technology adds semantic part into WSDL, and when user looks for a service, it compares each WSDL with user’s profile ontology. It uses schema-graph to implement comparing between WSDL and OWL, by this way, integrates ontology to grid.
