Context model for Web service composition
Qihe Liu · Journal of Computer Applications · 2009
Based on the context-aware computing,this paper proposed a novel context model for Web service composition.In this model,the information involved in the service composition was classified as service and user contexts,and the former was too distinguished as profile,conversation and grounding contexts;On the other hand,this paper adopted multi-policies to manage the contexts.Therefore,the policy description language extended by service was defined,and the language was based on(Event Condition Action) ECA rule.Not only the service policies were described by the above language,but also the description for composite service was realized by the language.The model not only sufficiently utilizes the context-aware computing,but also has good cooperation,expansibility and flexibility.
