Automated Semantic Web Service Composition Based on Enhanced HTN

AI planning is considered as the most effective means to compose web services automatically. In this paper, we choose an AI planning method called Hierarchical Task Network (HTN) and extend it to fit for usage of domain knowledge. We describe how HTN planning can be integrated with OWL-S Web Service descriptions, and introduce the system Architecture of a planner that support the service composition based on a set of OWL-S descriptions.
