Web services and agents are two important software devel- opment technologies that are aﬀected from the semantic web innova- tion. Researches for attuning these topics to the semantic web prepare a ground for integration of them. In this paper, a planner infrastruc- ture 1 is introduced that provides the integration of these two topics on the semantic web ground. Our approach is to support the semantic web service usage during agent planning process. Hence, agent can select re- quired external semantic services to satisfy a goal and can interact with the selected services during the plan execution. 1 Introduction The semantic web brings signiﬁcant innovation to the software development so- ciety by enabling the development of loosely coupled and independently evolving applications. In particularly, this innovation aﬀects the distributed application development technologies. Web services and agents are two of important dis- tributed application development technologies that must be improved according to the semantic web capabilities. Web services are self-deﬁned and distributed web applications. The semantic web evolution of web services intends to dynamic and more global service ex- ecution. This evolution initiated a new generation service technology, which is called semantic web services. Semantic web services provide dynamic discovery and more global execution. Currently eﬀorts such as OWL-S 2 , WSMF[6] and SWSA[3] are working for adapting web service environment to the semantic web service architecture. On the agent research direction, researchers have been attempting to develop agent infrastructures working on semantic web environment. These eﬀorts rein- force some of the agents’ core capabilities such as autonomy, intelligency and 1 This work is supported by The Scientiﬁc and Technological Research Council of Turkey (TÜBiTAK) Electric, Electronic and Informatics Research Group (EEEAG) under grant 106E008. 2 Web Ontology Language-Service, http://www.daml.org/services/owl-s/1.1/ R.
