为了实现更加灵活、智能的服务组合，应充分利用上下文信息。尽管已经提出了许多与上下文相关的方法来支持动态服务组合，但上下文表示和管理仍然是一个悬而未决的问题。在本文中，我们提出了一种多粒度上下文模型，该模型有效地利用了不同上下文属性之间的关系，以及相应的多粒度上下文管理方法，以增强动态服务组合的灵活性和智能性。所提出的多粒度上下文模型使得通过逻辑推理实现动态服务组合成为可能。通过案例研究和比较分析来说明我们方法的有效性。
In order to achieve more flexible and intelligent service composition, the context information should be fully utilized. Although many context-related approaches have been proposed to support the dynamic service composition, the context representation and management remains an open problem. In this paper, we propose a multi-granularity context model which effectively exploits the relationships among different context attributes, together with the corresponding multi-granularity context management approach to strengthen the flexibility and intelligence of dynamic service composition. The proposed multi-granularity context model makes it possible to achieve dynamic service composition through logical reasoning. A case study together with comparison analysis are presented to illustrate the validity of our approach.
