A method of services intelligent cooperative work for requirements based on integrated planning

With the number of web services increasing rapidly, we have to pay more attention to how to make full use of these services to meet the requirements of users. In this paper, we propose a method of services intelligent cooperative work for requirements based on integrated planning. The method gets requirements and domain knowledge based on domain ontology, builds a logical process using HTN planning based on the information that has been gotten before, and selects an instance of web service for every node in the logical process to meet the requirements. The selection of web services is represented by first-order logic satisfiability-based planning problem. We use hill climbing algorithm to solve this problem.
