摘　　要：This paper proposes a new business domain-oriented web service discovery method and framework to solve the low precision results caused by UDDI （universal description,discovery and integration） syntactic discovery and the difficulty in selecting from among functionally equivalent web services.When requesting services,service clusters are extracted from concrete services in terms of functional requests; then, through business information properties consultation,the most suitable services are determined and finally bound to user requests.The whole process is transparent to users. This framework is also tested and supported through a prototype based on a travel domain,IPVita （intelligent platform of virtual travel agency）.针对UDDI关键字匹配带来的服务发现精度低,以及难以从功能相同的多个web服务中选择合适服务的问题,提出一种新的面向业务领域的web服务发现方法和相关框架.当用户请求服务时,根据功能请求从实际服务中抽取出服务簇,然后由业务信息属性等非功能性属性进行协商,确定出适合的服务并与用户请求绑定,而整个发现过程对用户来说都是透明的.通过建立一个基于旅游领域的原型系统IPVita来测试和支持此框架.
