摘要 合成现有Web服务以生成功能更强更复杂的组合服务成为必然,组合服务的上下文信息具有十分重要的作用.针对Web服务描述语言仅支持服务功能性描述的不足,扩展了非功能属性描述,定义了一个Web服务的上下文模型,设计实现了感知上下文和执行动态服务替换的组合服务平台,通过运行旅游服务对该平台系统进行了有效验证. In order to incorporate services into composite service to satisfy users' complicated functional and non-functional needs,this paper puts forward a method to extend web services description.It establishes a context model of web service,and implements a composite platform for services.The platform fully considers influences of context on service composition,dynamic execution and quality controlling of web services.Finally a traveling system runs on the platform.
