Semantic Web Service Composition Planning with OWLS-Xplan ∗ 论文

摘要

We present an OWL-S service composition planner, called OWLS-Xplan, that allows for fast and flexible composition of OWL-S services in the semantic Web. OWLS-Xplan con-verts OWL-S 1.1 services to equivalent problem and domain descriptions that are specified in the planning domain descrip-tion language PDDL 2.1, and invokes an efficient AI plan-ner Xplan to generate a service composition plan sequence that satisfies a given goal. Xplan extends an action based FastForward-planner with a HTN planning and re-planning component.
