In this paper, a query planner is presented for semantic web services. Semantic web services represented in OWL-S format called OWL-S services. This planner converts OWL-S services to equivalent problem and domain descriptions that are specified in the planning domain description language PDDL. It invokes an efficient AI planner,Fast Diagonally Downward (FDD), to generate a sequence of OWL-S web services that satisfies a given goal. This planner will be called semantic web services-FDD (SWS-FDD). SWSFDD uses multi-valued state variables for PDDL-style planning and uses hierarchical task decompositions within a heuristic planning framework.
