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 J?schke 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 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.
Martin Atzmueller heads the Ubiquitous Data Mining Team at the Hertie Chair for Knowledge and Data Engineering, University of Kassel. He earned his habilitation (Dr. habil.) in 2013 at the University of Kassel, and received his Ph.D. in Computer Science from the University of Würzburg in 2006. He studied Computer Science at the University of Texas at Austin (USA) and at the University of Wuerzburg where he completed his MSc in Computer Science.
Stephan Doerfel achieved his diploma degree in mathematics after studies in Dresden (Germany) and Lund (Sweden). He focussed on Algebraic Structures and Formal Concept Analysis. Since 2009 he is a Ph.D.-student at the Knowledge and Data Engineering Group in Kassel (Germany).
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.
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".
Bj?rn-Elmar Macek studied Computer Science at the Technical University of Ilmenau with major focus on complexity theory, databases and data streams. After his graduation he got experienced in the field of industrial web development and consulting and the design and implementation of databases. In September 2009, he joined the Knowledge and Data Engineering team. Currently, he works on the Venus project.
