We are a research group at the Department of Computer Science at Leipzig University, Germany, led by Jun.-Prof. Dr. Leonie Weissweiler.

We work on linguistically-oriented natural language processing — asking what language models actually learn about the structure of language, and using insights from linguistic theory to build better, more interpretable NLP systems.
