Focus Group: Natural Language Processing and Information Retrieval

(Prof. Ponzetto and Prof. Glavaš)

The NLP and IR group at DWS conducts research on methods for knowledge acquisition and natural language processing (NLP), as well as their application to support empirical research in (Computational) Social Sciences and (Digital) Humanities. In our work, we investigate a wide range of techniques for text understanding - ranging from representation learning and distributional semantics all the way through symbolic, entity-based approaches leveraging wide-coverage knowledge graphs - and apply these to a wide range of research topics such as such computational semantics, multilinguality, information retrieval and multimodal NLP, to name a few.

Here is a short video that summarizes (in German and for the general public) some of the things that what we do in our group.
