Gottfried Wilhelm Leibniz Universität Hannover

Organisation Profile

The L3S Research Center is a joint research institute of several universities in Lower Saxony, Germany formally associated with Leibniz Universität Hannover (LUH). Work at L3S focuses on innovative and cuttingedge methods and technologies for Web Science, a key topic for the European Information Society, investigating the Future of Information and Communication in the Web Age. Projects investigate innovative scenarios and solutions in the Web Science areas of Web Search (especially Rich Media search and Entitycentric search), Web Information Management (including Digital libraries and semantic enrichment), Middleware for Web Infrastructures, the Future Internet and the Web of People (including Personalization, Diversity-aware services, and Social Web solutions). The L3S team builds upon technologies and approaches from various areas such as information retrieval, machine learning, natural language processing, semantic web technologies, data management, and Distributed and Peer-to-Peer Information Systems. The L3S team has a long experience in participating in European research projects, including the Web preservation projects LIWA, where the L3S team worked on topics such as terminology evolution, and ARCOMEM, which aims to exploit collective intelligence for easing human appraisal, and projects in related areas such as LivingKnowledge, GLOCAL, and SYNC3.

Role in the project

LUH will take the role of the coordinator of the ForgetIT project. Furthermore, LUH will focus on the development of the managed forgetting process, leading WP3 and on dealing with evolving semantics and evolution-aware contextualization contributing to WP 6. Furthermore, LUH will also be involved in the development of the organizational preservation application (WP10) and in integration activities (WP8).

CVs of key personnel

Prof. Wolfgang Nejdl

Prof. Wolfgang Nejdl has been full professor of computer science at the University of Hannover since 1995. He received his M.Sc. (1984) and Ph.D. degree (1988) at the Technical University of Vienna, was assistant professor in Vienna from 1988 to 1992, and associate professor at the RWTH Aachen from 1992 to 1995. He worked as visiting researcher / professor at Xerox PARC, Stanford University, University of Illinois at Urbana-Champaign, EPFL Lausanne, and at PUC Rio. Prof. Nejdl heads the Distributed Systems Institute / Knowledge Based Systems (http://www.kbs.uni-hannover.de/) as well as the L3S Research Center (http://www.l3s.de/), and does research in the areas of search and information retrieval, semantic web technologies, peer-to-peer information systems, technology-enhanced learning, databases and artificial intelligence. Relevant projects in the L3S context include the PHAROS Integrated Project on audio-visual search, the OKKAM IP focusing on entities on the Web, the Preservation EU project LiWA, coordinated by L3S, which investigated Web archive management and advanced search in such an archive, and the FET IP project Living Knowledge, which is developing algorithms and methods to handle and exploit diversity, bias and opinion on the Web. Wolfgang Nejdl published more than 190 scientific articles, as listed at DBLP, and has been program chair, program committee and editorial board member of numerous international conferences and journals.

Dr. Claudia Niederée

Dr. Claudia Niederée is a research group leader at the L3S Research Center in Hannover. Before she joined the L3S she worked at the Fraunhofer IPSI in Darmstadt, Germany. She holds a master in Computer Science and was awarded a doctoral degree in Computer Science by the Technical University Hamburg-Harburg (Germany). Her main research interests are diversity in knowledge, probabilistic databases, search, entitycentric technology and the Semantic Web. She has been the R&D manager of the FP7 IP OKKAM in the area of semantic-enabled knowledge systems of in the FET project LivingKnowledge that aims to building technology for better mastering the diversity in the Web and in the GLOCAL project on using event as a core concept in multimedia search. She also has been involved in the preservation projects LiWA and ARCOMEM.

Dr. Nattiya Kanhabua

Dr. Nattiya Kanhabua is a postdoctoral researcher at the L3S Research Center in Hannover, Germany since November 2011. She conducted her PhD study under the supervision of Prof. Kjetil Nørvåg at Dept. of Computer and Information Science, Norwegian University of Science and Technology (NTNU), Trondheim, Norway. The PhD study is a formal part of the project LongRec (Records Management over Decades). LongRec was a research project on persistent, reliable and trustworthy long-term archival of digital documents, with emphasis on the availability and use of documents. LongRec was initiated and coordinated by DNV, and performed in cooperation with NTNU, NR, and a number of business partners, with partial funding from the Norwegian Research Council. In February 2012, she successfully defended her PhD thesis entitled “Timeaware Approaches to Information Retrieval”, thus being awarded the PhD degree. Her general research interests are information retrieval, Web archiving, and Web and social media mining. In particular, her main research is in the area of Time-aware Information Access to a long-term archival domain.
