ParaCrawl Corpus release v9

This corpus is released as part of the ParaCrawl project co-financed by the European Union through the Connecting Europe Facility.

Release 9 is the final release for ParaCrawl Action 3: "Continued Web-Scale Provision of Parallel Corpora for European Languages".

ParaCrawl 9 brings new content and higher quality as the result of an improved pipeline with:

  • better PDF processing
  • language identification based on CLD2 full instead of lite
  • improved machine translation models (almost all neural) used to parallelize sentences
  • neural cleaning applied for the first time
With this version, we reach the best MT results ever obtained with ParaCrawl.

As a bonus, we release an English-Chinese corpus and monolingual data.

Data formats: 5 variations of each corpus are provided: 1. Bicleaner TXT format, 2. Bicleaner TMX format, 3. RAW corpus, 4. ROAM (anonymised) format and 5. Deferred crawling format containing pointers to URLs to recrawl the corpora on your end. Click on the icon for each language to show the download links. To effectively transform a TMX to a tab-separated text file Download TMXT tool. Also, if you use deferred crawled corpora, our reconstruction tool can prove useful.
WMT warning: ParaCrawl contribution to WMT has been permanent since 2018. Data sets from various ParaCrawl releases have been used in different shared tasks along the years. To make sure you get the right version of the exact data sets needed for these shared tasks, please download them directly from the links provided at WMT website .
