### 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.

### 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
- mc4_legal

`mc4_legal` 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:

```python
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)
