A method to integrate the Web services, agent skills, and human information for the user?s intentions satisfaction is proposed and discussed. The user?s intention is extracted and represented by goal models. This makes the imprecise intentions be evaluated. Based on the hierarchical task network (HTN) planning approach, a plan could be automatically generated for satisfying the user?s intention extracted from the entered service request string. A bookstore scenario is used to illustrate the proposed approach and a service requestor agent is introduced for implementation.
