Keynote Speakers


Dr. Stefan Gradmann is a full Professor in the Arts department of KU Leuven (Belgium) as well as director of the University Library. Besides his continuing focus on knowledge management and semantically based operations his research and teaching covers digital libraries and web based information architectures, with a special emphasis on the digital humanities. His third area of expertise is document management and document lifecycle management.
The overall background of his work is an integrated view of the scientific information lifecycle with emphasis on interoperability and open, standards based methods of modelling this scholarly information continuum - both in technical terms as in an e-scholarship perspective. He studied Greek, philosophy and German literature in Paris and Freiburg (Brsg.) and received his Ph.D in Freiburg in 1986 in German Literature Studies. He has worked as scientific librarian in various managerial positions and later was Deputy Director of the University of Hamburg Regional Computing Center before occupying a chair of Library and Information Science at Humboldt-Universität zu Berlin / Berlin School of Library and Information Sciences with a focus on knowledge management and semantically based operations from 2008 to 2013.
His working languages are German, English, French and Dutch.
Humanities Computing: Stefan was an international advisor for the ACLS Commission on Cyberinfrastructure for the Humanities and Social Sciences, and as such has contributed to the report “Our Cultural Commonwealth”. Furthermore, he has been leading the EC funded project Digitised Manuscripts to Europeana (DM2E).
Europeana: He has been heavily involved in building Europeana, the European Digital Library, from its very beginnings More specifically he was leading work on technical and semantic interoperability and has been a co-author of the graph based Europeana Data Model (EDM) and triggered Europeana's involvement in the LoD community. 
Presidence DGI: Since December 2008 Stefan Gradmann is president of the Deutsche Gesellschaft für Informationswissenschaft und Informationspraxis (DGI). With more than 1000 institutional and some 200 personal members DGI is a major player in the area of information science.


Towards a Semantic Research Library: Digital Humanities Research, Europeana and the Linked Data Paradigm

Libraries have been almost exclusively dealing with containers of content for centuries now and have left the generation and handling handling of content to others (authors and publishers). This distribution of roles has been triggered to some extent by the advent of print – as libraries now are approaching the End of the Gutenberg Galaxis and are increasingly confronted to the emerging Linked Data Web they will have to rethink their role profoundly: from handling containers they will have to evolve into content and contextualization agents. The Europeana Data Model (EDM)is presented in this context as an example of new technology enabling Digital Humanities Research that could figure prominently on the agenda of future Semantic Research Libraries. However, being up to these new opportunities in terms of content based and context driven services requires cultural changes on the libraries’ side: the keynote will discuss some of the terms and related thinking libraries need to get rid of in order to effectively adopt this paradigm shift. In case they operate this cultural change we might assist a triple win for Europeana, Digital Humanists and Libraries alike. 


Dr Michail Salampasis is an associate professor at the department of Informatics of the Alexander TEI of Thessaloniki. He holds a B.Sc. in Informatics (1993) from the department of Informatics of the ATEI of Thessaloniki in Greece. He has a Ph.D. in Computing from the School of Computing & Engineering of the University of Sunderland in UK (1997). He was candidate for the best PhD thesis award in UK. This is a significant acknowledgment of research work of exceptional quality. His main research interests are in applied and interdisciplinary studies in information science, including models and experiments related to information seeking behaviour, information seeking in large professional search systems, Web information seeking and evaluation, distributed information retrieval including source selection and results merging algorithms, search systems usability testing, information seeking using multiple strategies/interfaces. He currently is the coordinator of the Cost Action “Multilingual and Multifaceted Interactive Information Access (MUMIA)” and a Marie Curie Fellow at the Institute of Software Technology and Interactive Systems, Vienna University of Technology leading a research program for Personalised Federated Patent Search Systems (PerFedPat). Michail Salampasis is a member of various scientific organisations and special interesting groups, served as program and general chair in several conferences and has published about 60 papers in refereed journals, conferences and book chapters in various fields of computing.


Rethinking the Search Experience: What could professional search systems do better?

Web search engines have proved extremely effective and efficient using the “query box” paradigm and the use of ranked list of search results to find relevant information for general purpose retrieval tasks and normal (everyday) information needs. To a large extent this has led to the great success and exponential growth of the Web. It also increased the content which is available online (in many different languages), and the dynamics of Web 2.0+ data being produced.  

When using search technology comes to specific domains (e.g. patent, medical, scientific literature, media) and industries (e.g. pharmaceuticals, automotive) it is notable to mention that search systems have been used for more than 30 years now as an important method for information access.  However, as public general purpose search technologies are being used increasingly in the workplace as a result of the explosion of content becoming electronically available, and the workers are becoming more knowledgeable about search technologies, many more demands are placed upon professional search systems, demands which are not properly addressed by the underlying “isolated” model (both in terms of data and interaction) which general purpose search engines suggest. 

Usually an exploratory type of search is needed which is typically characterized by recall-oriented information needs and by high uncertainty and evolution or change of the information need. Additionally, the complexity of the tasks which need to be performed by professional searchers, which usually include not only retrieval but also information analysing and monitoring tasks, usually require association, pipelining and possibly integration of information as well as synchronization and coordination of multiple and potentially concurrent search views produced from different datasets, search tools and UIs. Many facets of search technology (e.g. exploratory search, aggregated search, federated search, task-based search, Information Retrieval (IR) over query sessions, cognitive IR approaches, Human Computer IR) aim to at least partially address these demands. 

This talk will present the various facets of state-of-the-art search technology research which can contribute to the development of search tools for next generation professional search systems. Additionally, it discusses arguments for a more generalised framework which will allow addressing how to aggregate or merge content from multiple sources or specialised search services, but also to focus on the needs of professional workers using search systems, and how they need to interact with multiple search tools, technologies and UIs. The main motivation of the talk is to present a framework and emerging technologies which will influence the design of next generation professional search systems.
