Dataset Card for MultiLegalPile: A Large-Scale Multilingual Corpus for the Legal Domain

Dataset Summary

The Multi_Legal_Pile is a large-scale multilingual legal dataset suited for pretraining language models. It spans over 24 languages and five legal text types. This version only contains data permissively licensed for commercial use.

Supported Tasks and Leaderboards

The dataset supports the tasks of fill-mask.

Languages

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

Dataset Structure

It is structured in the following format: type -> language -> jurisdiction.jsonl.xz

type is one of the following:

• caselaw
• contracts
• legislation
• other
• legal_mc4

legal_mc4 is a subset of the other type but is listed separately so it can be easily excluded since it is less permissively licensed than the other types.

Use the dataset like this:

from datasets import load_dataset

config = 'en_contracts'  # {language}_{type}
dataset = load_dataset('joelito/Multi_Legal_Pile', config, split='train', streaming=True)

'config' is a combination of language and text_type, e.g. 'en_contracts' or 'de_caselaw'. To load all the languages or all the text_types, use 'all' instead of the language or text_type (e.g., ' all_legislation').

Data Instances

The file format is jsonl.xz and there is one split available ("train").

The complete dataset (689GB) consists of four large subsets:

• Native Multi Legal Pile (112GB)
• Eurlex Resources (179GB)
• Legal MC4 (106GB)
• Pile of Law (292GB)
