Semantic Routing, Service Discovery and Service Composition Gregor Erbach German Research Center for Artificial Intelligence Language Technology Lab Saarbrücken, Germany www.dfki.de/lt/ Brussels, 04 March 2004 Workshop „New Communication Paradigms for 2020“ Vision: Semantic Routing • User makes a request, e.g. “I need to from Berlin to Brussels tomorrow, arrive by 10 a.m., and spend max. 250 Euro” • User need not – – – – – – – choose a device (e.g. phone, PDA, PC) choose a service (e.g. voice, e-mail, SMS) choose a network or protocol (internet, PSTN, GSM) specify a destination (phone number, URL) decompose the request (find information, book, pay) consider alternatives (air, train, bus) find a service provider (travel agent, booking site) Brussels, 04 March 2004 Workshop „New Communication Paradigms for 2020“ Objectives • Request is picked up by a networked sensor (room microphone, multimodal interface, „intelligent dialtone“) • Request is tagged semantically – attributes: sender, contents, context, constraints • Based on its semantic tag, request is routed to a service provider (IT system or human) – capabilities of service providers must be formally described • Initial service provider may decompose request and issue requests to other service providers recursively • Service provider given response to request Brussels, 04 March 2004 Workshop „New Communication Paradigms for 2020“ Challenges and Enabling Technologies • Semantic tagging of requests – Artificial Intelligence, Natural Language Processing, Speech Understanding, Ambient Intelligence • Formal semantic description of service providers – Semantic web (RDF/OWL), web service discovery (WSDL) • Semantic routing of requests and responses; overlay semantic network over physical infrastructure – Content-addressable networks, peer-to-peer communication • Request decomposition and service composition – Agent-based computing, grid computing, AI planning methods • Trust and Security – Social networks, rating, reputation, cryptography Brussels, 04 March 2004 Workshop „New Communication Paradigms for 2020“
