### Dataset Summary

The MultiUN parallel corpus is extracted from the United Nations Website , and then cleaned and converted to XML at Language Technology Lab in DFKI GmbH (LT-DFKI), Germany. The documents were published by UN from 2000 to 2009.

This is a collection of translated documents from the United Nations originally compiled by Andreas Eisele and Yu Chen (see http://www.euromatrixplus.net/multi-un/).

This corpus is available in all 6 official languages of the UN consisting of around 300 million words per language

### Supported Tasks and Leaderboards

The underlying task is machine translation.

### Languages

Parallel texts are present in all six official languages: Arabic (`ar`), Chinese (`zh`), English (`en`), French (`fr`),
Russian (`ru`) and Spanish (`es`), with a small part of the documents available also in German (`de`).

## Dataset Structure

### Data Instances

```
{
  "translation": {
    "ar": "قرار اتخذته الجمعية العامة",
    "de": "Resolution der Generalversammlung"
  }
}
```

### Data Fields

- `translation` (`dict`): Parallel sentences for the pair of languages.

### Data Splits

The dataset contains a single "train" split for each language pair.
