Andreas Hotho

Andreas Hotho is managing all activities around BibSonomy. He earned his Master`s Degree in information systems at the University of Braunschweig (Germany) in 1998. He worked from 1999 to 2004 at the Institute of Applied Informatics and Formal Description Methods (AIFB) at the University of Karlsruhe in the areas of text, data, and web mining, semantic web and information retrieval where he also received his PhD. Since 2004 he is a senior researcher at the University of Kassel. His focus is on the combination of machine learning/data mining and semantic web, called semantic web mining, and especially on text clustering/classification with background knowledge. He was involved in organizing several Knowledge Discovery and Ontology Learning workshops in conjunction with the ECML/PKDD and KDD conferences.

Robert Jäschke

Robert Jäschke is the head of our developer team. His research focus is on integration of algorithms for community detection, ranking and recommendations into folksonomy systems.

Gerd Stumme

Gerd Stumme is Full Professor of Computer Science. He is leading the Hertie Chair on Knowledge and Data Engineering at the University of Kassel, and full member of the Research Center L3S. Gerd Stumme earned his PhD in 1997 at Darmstadt University of Technology, and his Habilitation at the Institute Institute of Applied Informatics and Formal Description Methods (AIFB) of the University of Karlsruhe in 2002. In 1999/2000 he was Visiting Professor at the University of Clermont-Ferrand, France, and Substitute Professor for Machine Learning and Knowledge Discovery at the University of Magdeburg in 2003. Gerd Stumme published over 80 articles at national and international conferences and in journals, and chaired several workshops and conferences. He is member in the Editorial Boards of the Intl. Journal on Data Warehousing and Mining and of the International Conference on Conceptual Structures, and was also member of several conference and workshop Program Committees. Gerd Stumme is leading and led several national and European projects.

Beate Krause

Beate Krause studied Information Systems (Wirtschaftsinformatik) at the Berufsakademie Stuttgart (BA) and at the Humboldt University of Berlin (M.Sc.). Since October 2006 she is working in the Knowledge Discovery and Engineering team. Her current project is "Social Search: Bringing the social component to the web".

Dominik Benz

Dominik Benz obtained his Diploma in Computer Science with minor Psychology at the University of Freiburg, Germany in 2007. He is employed currently as a Ph.D. candidate in Computer Science at the University of Kassel, Germany, in the research unit Knowledge and Data Engineering. His main research interests lie in the area of collaborative knowledge management, ontology learning and collaborative tagging systems.

Former Associate: Christoph Schmitz

Christoph Schmitz has been a researcher in the research group on Knowledge and Data Engineering at the University of Kassel from April 2004 until obtaining his PhD in Oktober 2007. He received his diploma in Computer Science from the University of Trier in 2001. From 2002 until March 2004, he worked as a researcher for the Institute AIFB at the University of Karlsruhe, co-operating in the PADLR project with the Research Center L3S at the University of Hannover. His PhD thesis deals with collaborative knowledge management in peer-to-peer and folksonomy systems.
