Information Extraction and Interpretation, Uni Stuttgart

I head a group on Information Extraction and Interpretation, which is part of the chair of Theoretical Computational Linguistics at the IMS at Uni Stuttgart. Our main topic are the development of (typically statistical) models to structure textual information, for instance biomedical named entity recognition and relation extraction, slot filling, fine-grained sentiment analysis and emotion recognition. We are interested in developing high-performing models and at the same time to understand the (linguistic) properties of a task.
