| Description | The Czech Supreme Court produces significant amount of decisions totalling more than 130 000 decisions since 1993. The amount makes it difficult for law practitioners to research this case law. This work focuses on topic models for enhanced information retrieval through identification of case law approaching the same or similar issues. We provide initial quantitative evaluation of Latent Dirichlet Allocation (LDA) and Non-negative Matrix Factorization (NMF) models according to CV coherence score for different number of topics modelled n= {10, 20, ..., 90, 100}. Additionally, we provide qualitative evaluation for LDA and NMF models n= {20, 30} that will serve as a starting point for subsequent expert-user evaluation. |
