Model description
This is a tuned random forest classifiert, trained on a processed dataset of 2800 German court cases (see legalis dataset). It predicts the winner (defended/"Verklagtr" or plaintiff/"Klägerin") of a court case based on facts provided (in German).
Intended uses & limitations
- This model was created as part of a university project and should be considered highly experimental.

The modelHyperparameters
- The Classifier was tuned with scikit's cv search method, the pipeline used a CountVectorizer with common German stopwords.
