A general purpose multilingual corpus available in Sketch Engine

The EUR-Lex parallel corpus is a collection of multilingual corpora in all the official languages of the European Union. The corpus has been built from HTML files available in EUR-Lex database that consists of European Union law and other public documents of the EU. Thanks to the coverage of a vast area of subjects, the corpus is an excellent general purpose resource for anyone looking for translation examples in many languages.

A substantial part of the documents is translated into all official languages of the European Union (currently 24). Languages which joined the EU later are represented by smaller corpora proportional to the length of their membership.


Technically speaking, the documents are segmented and aligned on paragraph level. This means that the user can search for a matching paragraph containing the translation. The paragraphs are, however,  fine-grained and usually correspond with sentences which means that the user is able to search for matching sentences or very short paragraphs.

Sketch Engine offers also the smaller corpus of judgments of the European Parliament, see more.
