Papatheodorou

I am a Research Fellow with the Digital Curation Unit (DCU) of Athena Research Centre and also an assistant professor in the Department of Archive and Library Science , Ionian University . I received my B.Sc. and Ph.D. in Computer Science, both from the Department of Informatics , Athens University of Economics in 1987 and 1992 respectively. Before joining Ionian University I was in charge of the development of Digital Library and Information Services at the Library of the National Centre for Scientific Research “Demokritos” in Athens, Greece. I participate to the join research tasks of Semantic Interoperability, and Digital Library Evaluation of theDELOS Network of Excellence on Digital Libraries , and I was project proposal evaluator for the Information Society Technologies (IST) program, 5th EU R&D Program-Framework, Action Line: Digital Collections – Cultural Heritage.

My research interests include:

  1. Metadata interoperability and especially ontology-based interoperability of cultural heritage and e-government metadata schemas.
  2. Evaluation of Digital Libraries and Information Services, focusing on user-based evaluation and user behavior analysis.
  3. User Modeling, Personalized access to Digital Libraries and Internet, Information Filtering and Web Mining focusing on the discovery of user communities and sterotypes.
  4. Web 2.0 technologies, such as social tagging system, folksonomies, etc. focusing on the integration and interoperability of such technologies with knowledge organization systems and metadata standards.
