Use Agent to Compose Web Service Dynamically

Traditional method of composing Web service is inflexible and inefficient because exogenous event can not handle in run-time. In this article, an expansion way is raised to settle this problem. A dynamic composite web service structure is given and an agent is used to handle the exogenous event when service is running. In order to dynamic reasoning activities of service, the agent language will be expensed by adding operators "ldr", "Sexo" and "Sintent". We also give the action expression and mental state of the agent and the translation from the service DAML to mental state.
