Research Interests

Machine Learning (especially graphical models)
Active Learning (especially efficient approaches to real-world learning and annotation problems)
Named Entity Recognition and Normalization
Natural Language Processing of biomedical texts
NLP Frameworks (i.e. UIMA, GATE)
Annotation "as a science" (modelling annotation costs and the annotation process, cost-conscious methods to training material creation)
Application of above methods for large-scale information extraction and data mining
