Dataset Card for OpusParaCrawl

Dataset Summary

Parallel corpora from Web Crawls collected in the ParaCrawl project.

Tha dataset contains:

• 42 languages, 43 bitexts
• total number of files: 59,996
• total number of tokens: 56.11G
• total number of sentence fragments: 3.13G

To load a language pair which isn't part of the config, all you need to do is specify the language code as pairs, e.g.

dataset = load_dataset("opus_paracrawl", lang1="en", lang2="so")

You can find the valid pairs in Homepage section of Dataset Description: http://opus.nlpl.eu/ParaCrawl.php
