Topic Modeling for Swiss Court Rulings

Joel Niklaus is a PhD student in the research project NRP77 "Open Justice vs. Privacy" at the Digital Sustainability Research Center at the Institute for Computer Science at the University of Bern. His work focuses on the anonymization and de-anonymization of court decisions. Joel Niklaus graduated in 2019 from the University of Bern with a Master's degree in Computer Science with a focus on Data Science and Sports Science. In his master thesis, he worked out artificial intelligence for Jass on the level of strong amateur players. From 2016 - 2020 he was a lecturer for ICT and the compulsory subject of computer science at Swiss high schools.
