Andreas Hotho is the Project lead of 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 2009 he is professor for data science at the Julius-Maximilians-Universität Würzburg. 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.
