Service composition based on facilitator federation
In this paper, we present our approach of facilitator federation that allows automatic service composition in distributed systems. We propose a facilitator based on ontologies and knowledge representation that allows clients to discover services without direct interactions with their providers. We extend the functionality of the facilitator to be a composition engine and we show how several facilitators can interact to compose services and to satisfy the client's requests. Our approach can be used in peer-to-peer networks.
