中文摘要：
为了适应环境和上下文信息的动态变化并提供适时适地的服务，Web服务组合要能满足处于动态变化环境中的个性化用户需求。文中提出了一个基于模板和上下文的语义Web服务组合框架，该框架使用抽象服务流程进行Web服务组合建模，利用本体来进行上下文信息建模并支持基于JESS的上下文信息推理，在原有基于语义的Web服务匹配的基础上，实时地感知上下文信息来进行Web服务动态绑定。该方法提高了服务组合的成功率和动态适应性，并且满足了用户的个性化需求。
英文摘要：
In order to adapt to the dynamic changes of environment and context information and to provide appropriate services, the Web services composition not only has to meet the user＇s individual requirements, but also adapts to environmental changcs. A system framework based on templet and context information is presented, which uses abstract services process model in services composition modeling and uses ontology - based context information modeling which supports JESS- enabled elicitation. At the basis of semantic - based Web service matching, the framework binds the Web service dynamically through real - time context - aware information. This framework improves the success rate and the dynamic adaptability of Web services composition and meets the user＇s individual requirements.
