### Dataset Summary

The Multi_Legal_Pile is a large-scale multilingual legal dataset suited for pretraining language models.
It spans over 24 languages and four legal text types. 

### 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:
text_type -> language -> jurisdiction.jsonl.xz

text_type is one of the following:

- caselaw
- contracts
- legislation
- other

The dataset can be used in the following way:
```
from datasets import load_dataset

config = 'en_contracts'
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 (563GB) consists of four large subsets:
- Native Multi Legal Pile (29GB)
- Eurlex Resources (179GB)
- MC4 Legal (133GB)
- Pile of Law (222GB)

For simplicity and with respect to balancing off data across different jurisdictions and languages,
we disregard many US resources that are either very specialized (e.g., tax rulings),
outdated/historical (e.g., founding letters),
very small (less than 20MB),
not legal language in the strict sense (conversations),
or the information overlaps with other sources (study materials).
If you are interested in a US-based (US-biased) model, refer to the "Pile of (US) Law" by Henderson et al. (2022).
Analyses are put into the "other" category because in mc4_legal we also likely have similar text.
