中文摘要： 在当前Internet开放、动态以及用户需求多变的环境下，Web服务及其组合需要突破传统软件的静态和封闭框架体系，主动感知外部环境的动态变化，并随着这种变化按照功能和性能指标进行动态调整和演化，以使组合系统具有更高的灵活性和用户满意度。为此，本项目研究上下文感知的Web服务自适应计算模型，引入基于上下文感知进程网络（Context-aware Process Network，CAPN）的Web服务组合建模方法, 解决上下文感知Web服务的行为交互和个性化选择等问题；研究上下文感知Web服务及其组合的自适应技术，提供上下文获取、分类和建模方法，上下文感知Web服务的行为自适应策略和上下文感知Web服务组合的动态演化机制；设计一种新的基于CAPN的上下文感知Web服务组合建模语言，并给出该语言描述的组合Web服务到可运行系统的转换机制，实现基于CAPN的Web服务组合解释器。

英文摘要： The today's Internet is open and dynamic and user demand is also changeable. Under this environment, Web services and their composition need to break through static and closed architecture of traditional software, need to be aware of the dynamic changes of external environment initiatively and to adjust and evolve dynamically according to function and performance indicators, to make composed system have high flexibility and user satisfaction degree. So, in this project, context-aware adaptive computation model of Web services will be researched. Context-aware Process Network(CAPN) based modeling method for Web service composition will be introduced to solve the problems of behavior interaction and personalized selection of context-aware Web service. Self-adaptation technologies of context-aware Web service and their composition will be researched to provide contexts obtaining, classifying and modeling methods, behavior self-adaptation strategy of context-aware Web service and dynamic evolution mechanism of context-aware Web service composition. A novel context-aware Web service composition language based on CAPN will be designed and the conversion mechanism from composed Web service described by this language to executable system will be provided to realize the CAPN based Web service composition interpreter.
