We are happy to announce that the 2016 update release of the DGT-Translation Memory (DGT-TM) is now available for download.

This year’s release is particularly large, adding 22 million translation units (~ sentences) – or 373 million words – to the collection.

With this update, a total of 111 million translation units is now available for download, equivalent to 1.85 billion words.

DGT-TM is an extraction of the translation memory of the European Institutions for all 24 official EU languages, produced by the European Commission’s Directorate General for Translation (DGT) and distributed by the Joint Research Centre (JRC). Translation memories are sentences and their manually produced translations.

The new release is called DGT-TM-2016. It follows the previous releases DGT-TM (2007), DGT-TM-2011, DGT-TM-2012, DGT-TM-2013, DGT-TM-2014 and DGT-TM-2015.

New features of DGT-TM-2016 are:

· Croatian (HR) data triples in size.

· About 915K new translation units per language.

· More data for language pairs involving Maltese are available on request.

Languages: All 276 language pairs involving the following 24 languages:

Bulgarian, Croatian, Czech, Danish, Dutch, English, Estonian,

German, Greek, Finnish, French, Irish, Hungarian, Italian,

Latvian, Lithuanian, Maltese, Polish, Portuguese, Romanian,

Slovak, Slovene, Spanish and Swedish.

The ‘ <http://europa.eu/abc/eurojargon/index_en.htm> Acquis Communautaire’ is the entire body of European legislation, comprising all the treaties, regulations and directives adopted by the European Union (EU). Since each new country joining the EU is required to accept the whole Acquis Communautaire, this body of legislation has been translated into 23 official languages. For the 24th official EU language, Irish, the Acquis has not been translated on a regular basis; which is why DGT-TM includes less data in Irish. The Acquis Communautaire was split into sentences and aligned automatically at sentence level, resulting in the DGT translation memory, DGT-TM. Small parts of the alignment data have been corrected by translators. The text data is accompanied by software that allows to extract all sentences and their translations for any of the 276 possible language pair combinations.


The public data release is in line with the general effort of the European Commission to support multilingualism, language diversity and the re-use of Commission information. It follows the release of a number of further multilingual data sets:

· the JRC-Acquis parallel corpus in 2006 (over 1 billion words in 22 languages),

· the DGT-TM Translation Memory in 2007,

· the multilingual named entity resource JRC-Names in 2011 (and its Linked Data version in 2016),

· the multilingual multi-label classification tool (and accompanying text data) JRC EuroVoc Indexer (JEX) (22 languages) in 2012,

· the ECDC-TM Translation Memory in 2012 (domain: Public Health)

· the DGT-Acquis parallel corpus in 2012,

· the EAC-TM Translation Memory in 2013 (domain: Education and Culture),

· the DCEP (Digital Corpus of the European Parliament) in 2014,

· and further smaller multilingual resources.

See https://ec.europa.eu/jrc/en/language-technologies for more information on these resources.


DGT-TM can be fed into translation memory software to support human translators in their work. As it is a large parallel corpus in electronic form, it can furthermore be used by specialists in computational linguistics to train statistical machine translation software, to generate multilingual dictionaries, to train and test multilingual information extraction software, and more.
