EuroPat: Unleashing European Patent Translations

Patents provide a rich source of technical vocabulary, product names, and person names that complement other data sources used for machine translation.

This Action will will mine parallel corpora from patents by aggregating, aligning, and converting patent data. Alignment and cleaning modules in the ParaCrawl pipeline will be enhanced and used to carry out this action.

The first release includes English-German (12.6M parallel sentences) and English-French corpora (9.2M parallel sentences) made up by using information from the European Patent Organisation database to identify patents.

Implementation schedule: September 2010 to September 2021
