About

Hagen Langer is senior researcher at the University of Bremen since 2004. His research interests include natural language processing, knowledge representation, multiagent systems, and machine learning. He received a doctoral degree from Georg-August-Universität Göttingen and he also holds a habilitation from the University of Osnabrück. From 2008 to 2011, Hagen Langer was principal investigator in the subproject B4 Knowledge Management of the Collaborative Research Center 637 Autonomous Cooperating Logistic Processes - A Paradigm Shift and its Limitations ([http://www.sfb637.uni-bremen.de/sfb637.html?&L=2]).
