It is a challenge for Web service composition to perceive dynamic changes of external environment and adapt to the changes of business process rapidly. In this paper, a context-aware adaptive Web service composition framework is presented and the functions of main modules are also described in detail. In this framework, BPEL is used to describe Web service composition process and a kind of special Web service called context service is defined to support context-awareness. Agent technology is introduced to enable context service to actively perceive and process contexts of Web service and Web service composition.
