Reasoning about interaction protocols for customizing web service selection and composition

摘要

This work faces the problem of automatic selection and composition of web services, discussing the advantages that derive from the inclusion, in a web service declarative description, of the high-level communication protocol, that is used by the service for interacting with its partners, allowing a rational inspection of it. The approach we propose is set in the Semantic Web field of research and inherits from research in the field of multi-agent systems. Web services are viewed as software agents, communicating by predefined sharable interaction protocols. A logic programming framework based on modal logic is proposed, where the protocol-based interactions of web services are formalized and the use of reasoning about actions and change techniques (planning) for performing the tasks of selection and composition of web services in a way that is personalized w.r.t. the user request is enabled. We claim that applying reasoning techniques on a declarative specification of the service interactions allows to gain flexibility in fulfilling the user preference in the context of a web service matchmaking process.
