A Planning Engine Based on SHOP2 for AFLOW

OWL-S is designed to support semantic and automated composition of Web services. AFLOW is a composition system, based on OWL-S, combining AI planning and workflow technology. In this paper, we discuss the implementation of the AI planning subsystem in the AFLOW, supporting higher dynamic and automation of composition. And we describe how an AI planning system (SHOP2) can be used with OWL-S Web service type descriptions in AFLOW to automatically compose Web services and support partial concurrency in OWL-S.
