2. 15/02/2007Athens Meeting 2 A few words about NCSR  National Centre for Scientific Research (NCSR) “Demokritos” –Largest self-governing research organisation under the supervision of the Greek government –Subdivided in 8 research institutes Biology, Material Sciences, Microelectronics, Informatics & Telecommunications, Nuclear Technology – Radiation Protection, Nuclear Physics, Radioisotopes & Radiodiagnostic products, Physical Chemistry  In INDIGO with the Institute of Informatics & Telecommunications –Software & Knowledge Engineering Lab (SKEL)

3. 15/02/2007Athens Meeting 3 and about SKEL … Information Integration User-friendly information access Ontology Creation and Maintenance SKEL researchers aim to develop knowledge technologies that will enable the efficient, cost-effective and user-adaptive management and presentation of information

4. 15/02/2007Athens Meeting 4 Applied Research at SKEL … –The general-purpose language engineering platform Ellogon –Language processing tools and resources –The i-DIP platform for developing web content collection and extraction systems –The QUAPRO proxy server, for validating RDF labels of web resources –The FILTRON e-mail filter, that blocks unsolicited commercial e-mail (spam messages) –The FilterX Web proxy filter, that blocks obscene Web content –Tools for creating and maintaining ontologies –The PServer general-purpose server for personalization –Authoring tool for natural language generation systems

5. 15/02/2007Athens Meeting 5 Basic Research at SKEL … –Ontology learning –Ontology coordination –Document Summarization –Ontology-based information extraction –Reasoning –Natural language generation –Web usage mining

6. 15/02/2007Athens Meeting 6 SKEL team at INDIGO  Vangelis Karkaletsis –Senior researcher, Head of SKEL  Georgios Paliouras –Researcher  Stasinos Konstantopoulos –Post-doctoral researcher  Thanasis Tegos –MSc student  Dimitris Bilidas –Research associate

7. 15/02/2007Athens Meeting 7 SKEL infrastructure for INDIGO  Personalisation Server (PServer) –General personalisation framework Independent of particular applications. Able to adapt to application parameters. Covers a wide range of services and functionality. Easily expandable. Easy to set up and use by ongoing projects. –PServer operation Application initializes the service by defining & organizing the particular features. Continually notifies PServer on user choices. Application can pose questions at any time

8. 15/02/2007Athens Meeting 8 SKEL infrastructure for INDIGO  Authoring tool for NLG applications –Originally developed in the context of the M-PIRO project –Being extended in cooperation with AUEB team –Currently is able to Import OWL-DL ontologies Perform consistency checking using the reasoning engine RACER Export ontologies in OWL and linguistic and user modeling resources in RDF Interact with AUEB’s NaturalOWL NLG engine (a previous version with UEDIN’s Exprimo NLG engine)

9. 15/02/2007Athens Meeting 9 Extensions needed for INDIGO  PServer –Maintain both the users models and the robotic personality models –Integrate new services  Authoring Tool –Interact with both NLG engines –Support for spatial expressions –Support for INDIGO’s mark up scheme
