  1. Semantic Web-Services or Semantic-Web Services?Matthew Montebello CSAW’04 CSAW’04 M.Montebello

  2. Agenda • Welcome – some thoughts • What happened since CSAW’03 ? • Web Services and Semantic Web • What dilemma? • Work by the Agent Tech. research group • Conclusions CSAW’04 M.Montebello

  3. One year since CSAW’03 • WWW2: Second Generation Web • Semantic Web • Web Services • Ontologies • MarkUp Languages CSAW’04 M.Montebello

  4. Web Services • A software system identified by a URI • Its public interfaces and bindings are defined and described using XML • Its definition can be discovered by other software systems • These systems may then interact with the Web service in a manner prescribed by its definition, using XML based messages conveyed by Internet protocols CSAW’04 M.Montebello

  5. Semantic Web • An extension of the current web in which information is given well-defined meaning • An abstract representation of data on the World-Wide Web, based on RDF • It is being developed by the W3C, in collaboration with a large number of researchers and industrial partners • Machine readable and processable CSAW’04 M.Montebello

  6. What Dilemma? • Semantic Web-Service • Semantic-Web Service • Basic tasks: • Discovery • Invocation • Composition • Monitoring CSAW’04 M.Montebello

  7. Intelligent Software Agents Group • Research students • FYP students • AgentLink III • REWERSE CSAW’04 M.Montebello

  8. People • Charlie Abela • Malcolm Attard • James Scicluna • Wayne Grixti • AnnaMaria Cassola • Simon Scerri • Albina Pace • Alexiei Dingli CSAW’04 M.Montebello

  9. Ongoing work & projects • http://www.cs.um.edu.mt/~rewerse/ • Semantic Web Search Engine • OWL-S/BPEL (Business Process Execution Language)editor • Ontology engineering tools • Reasoning on the Web • Semantic Web Browsing • Web Service Composition using Planning and Reusable Plans CSAW’04 M.Montebello

  10. Conclusion • OWL-S developed on top of XML, will facilitate the transition • Agent markup languages will enable search engines to go beyond Boolean searches and use natural language instead • RDF will help integrate and aggregate applications to make the Web more like a library cataloge CSAW’04 M.Montebello
