Innovative Information and Knowledge Infrastructures
This event took place on Wednesday 07 December 2005 at 12:30

 
Wolfgang Nejdl Learning Lab Lower Saxony [L3S], University of Hannover, Germany

L3S research focuses on three key enablers for the European Information Society, namely Knowledge, Information and Learning, and combines this with a strong commitment to service to its affiliated universities in the field of eLearning. The first part of the talk will review my project background in this context and highlight some of the projects currently running at L3S under my supervision.

The second part focuses on "Personal Information Management" as guiding theme for several of these projects. Personal information management infrastructures provide advanced functionalities for accessing information from institutional repositories / digital libraries as well as personal collections, and facilitate knowledge sharing and exchange in work and learning contexts. Federated and peer-to-peer infrastructures, integrated search on metadata and full-text collections, and advanced personalization and ranking algorithms play an important role in this context.

Semantic Web and Knowledge Services is...


Semantic Web and Knowledge Services
"The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation" (Berners-Lee et al., 2001).

Our research in the Semantic Web area looks at the potentials of fusing together advances in a range of disciplines, and applying them in a systemic way to simplify the development of intelligent, knowledge-based web services and to facilitate human access and use of knowledge available on the web. For instance, we are exploring ways in which tnatural language interfaces can be used to facilitate access to data distributed over different repositories. We are also developing infrastructures to support rapid development and deployment of semantic web services, which can be used to create web applications on-the-fly. We are also investigating ways in which semantic technology can support learning on the web, through a combination of knowledge representation support, pedagogical theories and intelligent content aggregation mechanisms. Finally, we are also investigating the Semantic Web itself as a domain of analysis and performing large scale empirical studies to uncover data about the concrete epistemologies which can be found on the Semantic Web. This exciting new area of research gives us concrete insights on the different conceptualizations that are present on the Semantic Web by giving us the possibility to discover which are the most common viewpoints, which viewpoints are mutually inconsistent, to what extent different models agree or disagree, etc...

Our aim is to be at the forefront of both theoretical and practical developments on the Semantic Web not only by developing theories and models, but also by building concrete applications, for a variety of domains and user communities, including KMi and the Open University itself.
