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 the DELOS 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:
- Metadata interoperability and especially ontology-based interoperability of cultural heritage and e-government metadata schemas.
- Evaluation of Digital Libraries and Information Services, focusing on user-based evaluation and user behavior analysis.
- User Modeling, Personalized access to Digital Libraries and Internet, Information Filtering and Web Mining focusing on the discovery of user communities and sterotypes.
- 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.

I was Organizing Chair of the 11th International Conference on User Modeling (UM 2007) , Corfu, Greece, 25-29 June 2007, and I have participated in the program committee of the following conferences and workshops: AINA-08 , AINA-07 , ICEG-2006 , SETN2006 , ECDL 2005 , PIA 2005 , SETN2004 , SETN2002 , WEBKDD\'99 .
ProjectsAdvanced Research Infrastructure for Archaeological Dataset Networking in Europe
Local content in a Europeana cloud
ARIADNE is a proposal to bring together and integrate the existing archaeological research data infrastructures so that researchers can use the various distributed datasets and new and powerful technologies as an integral component of the archaeological research methodology. There is now a large availability of archaeological digital datasets that altogether span different periods, domains and regions; more are continuously created as a result of the increasing use of IT. They are the accumulated outcome of the research of individuals, teams and institutions, but form a vast and fragmented corpus and their potential is constrained by difficult access and non-homogenous perspectives.
This integrating activity will enable trans-national access of researchers to data centres, tools and guidance, and the creation of new Web-based services based on common interfaces to data repositories, availability of reference datasets and usage of innovative technologies. It will stimulate new research avenues in the field of archaeology, relying on the comparison, re-use and integration into current research of the outcomes of past and on-going field and laboratory activity. Such data are scattered amongst diverse collections, datasets, inaccessible and unpublished fieldwork reports “grey literature”, and in publications, the latter still being the main source of knowledge sharing. It will contribute to the creation of a new community of researchers ready to exploit the contribution of Information Technology and to incorporate it in the body of established archaeological research methodology.
To achieve this result the project will use a number of integrating technologies that build on common features of the currently available datasets, and on integrating actions that will build a vibrant community of use. The overall objective outlined above will be achieved through subordinate goals, which altogether will enable the provision of advanced Integrated Infrastructure.
3D Digitisation of Icons of European Architectural and Archaeological Heritage
LoCloud aims to build on the achievements of CARARE in establishing a repository-based aggregator for Archaeological and Architectural heritage and of Europeana Local in its work with local institutions and their regional and national aggregators, which resulted in the contribution to date of well over 5 million items to Europeana.
–continue to ease the task of enabling heritage organisations in making their contents accessible via Europeana, by using cloud technologies to provide services and tools which help to reduce technical, semantic and skills barriers
–to facilitate aggregation of digital content from small and medium cultural institutions, to be made available to Europeana;
–to enable smaller institutions such as house-museums to contribute their content to Europeana;
–to explore the potential of cloud computing for aggregation, enrichment and re-use, with a special focus on geographic location.
MOPSEUS: digital library service
This project proposes to digitise a series of architectural and archaeological masterpieces of world and European cultural significance and provide 3D models and related digital content to Europeana, with the aim of contributing to the critical mass of highly engaging content available to users.
Connecting ARchaeology and ARchitecture in Europeana
Mopseus is a digital library system based on Fedora-commons which allows the mangameent of digital resources emphasizing in digital preservation.
