Polish SCOTUS-Dom

Polish SCOTUS-Dom is a long-document legal text classification dataset derived from the publicly available SCOTUS dataset.

The dataset contains Polish translations of U.S. Supreme Court opinions. The task is an 11-class document classification problem in which the goal is to predict the legal issue area of a court case.

SCOTUS-Dom is part of the LongContext benchmark introduced with Polish ModernBERT.

Dataset statistics

The dataset contains particularly long documents: 74.5% of test examples exceed 4,096 tokens when tokenized with the Polish ModernBERT Base tokenizer.

Dataset construction

The original English court opinions were translated into Polish using GLM-4.6. The original SCOTUS train, validation, and test splits and task labels were retained.
