Abstract
In the last decade there has been a proliferation of web servicesbased application systems. In some applications (e.g., e-commerce,weather forecast) a web service is invoked many times with differentactual parameters to obtain a composed service. In this paper we introducethe notion of iterated services that are obtained from given atomicservices by iteration. The iterated services provide compact and elegantsolutions to such complex composition problems that are unsolvableusing the existing approaches.We define a new service dependency graphmodel to capture web services with sets of objects as input/output. Wegive a translation of the web services composition problem to a planningproblem. Finally, we transform a plan to a composed web service. Wehave implemented our approach using the BlackBox planner.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
