  1. NCSR at INDIGO Vangelis Karkaletsis Kick-off Project Meeting Athens, 15 February 2007

  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) Athens 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 Athens 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 Athens Meeting

  5. Basic Research at SKEL … • Ontology learning • Ontology coordination • Document Summarization • Ontology-based information extraction • Reasoning • Natural language generation • Web usage mining Athens 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 Athens 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 Athens 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) Athens 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 Athens Meeting
