Leonie Weissweiler

I am a first-year PhD student at the Center for Information and Language Processing at LMU Munich. My supervisor is Hinrich Schütze.

Previously, I completed my B.Sc. and M.Sc. degrees in Computational Linguistics and Computer Science at LMU, with scholarships from the German Academic Scholarship Foundation and the Max Weber Program. My M.Sc. thesis, supervised by Hinrich Schütze, was on the application of Complementary Learning Systems Theory to NLP. I spent the final year of my bachelor's degree as a visiting student at Homerton College, University of Cambridge, where I wrote my B.Sc. thesis on Character-Level RNNs under the supervision of Anna Korhonen.

I'm also the Erasmus coordinator and the contact for TUM students thinking about doing their 'Anwendungsfach' at CIS. Before emailing me about Erasmus, please read through the information on the website, especially the FAQs.

Current Research Interests
  • Emergent structure in language
  • Interactions between Cognitive Science and NLP
  • Cognitively plausible neural language models
  • Nonsymbolic representations
  • Alternatives to formal syntax and semantics

Stemmers, which reduce words to their stems, are important components of many natural language processing systems. In this paper, we conduct a systematic evaluation of several stemmers for German using two gold standards we have created and will release to the community. We then present our own stemmer, which achieves state-of-the-art results, is easy to understand and extend, and will be made publicly available both for use by programmers and as a benchmark for further stemmer development.
