Dataset Card for MC4_Legal: A Corpus Covering the Legal Part of MC4 for European Languages

Table of Contents

Dataset Description

Dataset Summary

This dataset contains large text resources (~106GB in total) from mc4 filtered for legal data that can be used for pretraining language models.

This dataset uses a different filtering method compared to mc4_legal and uses the smaller filtered c4 dataset for the English split to speed up the filtering.

Use the dataset like this:

from datasets import load_dataset
dataset = load_dataset("joelito/mc4_legal", "de", split='train', streaming=True)

Supported Tasks and Leaderboards

The dataset supports the task of masked language modeling.

Languages

The following languages are supported: bg, cs, da, de, el, en, es, et, fi, fr, ga, hu, it, lt, lv, mt, nl, pl, pt, ro, sk, sl, sv

Dataset Structure

Data Instances

The file format is jsonl.xz and there is a validation and train split available.

Dataset Creation

The dataset was created by filtering mc4 for legal data. We used terms indicating legal citations to get the texts. Note that this dataset can be quite noisy, and the quality is not known.
