Synthesis Of Underspecified Composite E-services Based On Automated Reasoning. E Ediz. Italiana E Inglese

In this paper we study automatic composition synthesis of e-Services, based on automated reasoning.The behavior of an e-Service is represented in terms of a deterministic transition system (or a finite state machine), in which for each action the role of the e-Service, either as initiator or as servant, is highlighted. In this setting we present an algorithm based on a Description Logic that solves the automatic composition problem. Specifically, given (i) a possibly incomplete specification of the sequences of actions that a client would like to realize, and (ii) a set of available e-Services, our technique synthesizes a composite e-Service that (i) uses only the available e-Services and (ii) interacts with the client “in accordance” to the given specification. We also study the computational complexity of the proposed algorithm.
