Dataset Summary

The dataset consists of 11 diverse multilingual legal NLU datasets. 6 datasets have one single configuration and 5 datasets have two or three configurations. This leads to a total of 18 tasks (8 single-label text classification tasks, 5 multi-label text classification tasks and 5 token-classification tasks).

Use the dataset like this:

from datasets import load_dataset
dataset = load_dataset("joelito/lextreme", "swiss_judgment_prediction")

Supported Tasks and Leaderboards

The dataset supports the tasks of text classification and token classification. In detail, we support the folliwing tasks and configurations:
