Welcome to the website of University of Passau’s Natural Language Processing (CAROLL) Group! We are a dynamic research group at the Faculty of Computer Science and Mathematics. We focus on Computational Rhetoric techniques applied to Sentiment Analysis, Offensive language modelling and detection, Legal Tech, Argumentation Mining and other areas of NLP.

To this end, we combine this approach with argument mining, also a research area within NLP. Argumentation mining is already used in social media to identify offensive language. However, the technology has so far reached its limits. She does not recognize irony or unobtrusive insults. The team will test whether the Passau approach is capable of this in heated debates on the topics of the climate crisis and vaccination criticism.

The project on which this research group is based is funded by the German Federal Ministry of Education and Research (BMBF) along with the University of Passau.
