| # Polish SCOTUS-Dec |
|
|
| **Polish SCOTUS-Dec** is a long-document legal text classification dataset |
| derived from the publicly available |
| [SCOTUS](https://huggingface.co/datasets/pasinit/scotus) dataset. |
|
|
| The dataset contains Polish translations of U.S. Supreme Court opinions. |
| The task is a **binary document classification problem** in which the goal |
| is to predict the ideological direction associated with the court decision: |
| **liberal** or **conservative**. |
|
|
| SCOTUS-Dec is part of the **LongContext** benchmark introduced with |
| [Polish ModernBERT](https://arxiv.org/abs/2609.01379). |
|

| ## Dataset statistics |
|
|
| | Split | Examples | |
| |---|---:| |
| | Train | 7,413 | |
| | Validation | 912 | |
| | Test | 931 | |
| | **Total** | **9,256** | |
|
|
| SCOTUS-Dec uses the same court opinions and dataset splits as SCOTUS-Dom. |
|
|
| 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. |
