摘要 介绍了一种扩展UDDI以支持语义信息的方法,即在注册Web服务时添加语义信息,并支持基于语义的查询。首先在UDDI系统中加入一个领域本体库,再为该UDDI中的每个注册服务添加语义信息,并将服务和本体库的对应关系存入到UDDI的数据库中。在服务申请者查询Web服务时,由用户提供语义查询模板,根据用户描述的本体语义信息得到候选服务列表,再根据用户对服务质量的要求计算候选服务的匹配度,将候选服务依照其匹配度的大小顺序返回给用户。 Introduce a method to extend UDDI to support semantic discovery and provide candidate Web sen-ices for Web service composition. At first add a domain ontology base into the UDDI system, then add semantic information for every registered Web service. At last, save the relation between Web service and ontology base into database. When Web service applicant query Web service or Web service compoeer saareh his needed service, the user provides semantic query template. Get the candidate service list based on the described ontology semantic intormation and calculate the matching degree of every candidate service and order them by their matching degree. At last, return the service list to the user.
