DCEP: Digital Corpus of the European Parliament



The Digital Corpus of the European Parliament (DCEP) contains the majority of the documents published on the European Parliament's official website. It comprises a variety of document types, from press releases to session and legislative documents related to European Parliament's activities and bodies. The current version of the corpus contains documents that were produced between 2001 and 2012.

Format and Structure of the Data

DCEP is available as full-text documents and as sentence-aligned data. DCEP includes alignment information for the full documents, as well as for sentences, produced separately for each language pair. DCEP is accompanied by tools that allow to produce sentence-aligned corpora separately for each of the 276 language pairs. The sentence-aligned data is in plain text format, i.e. XML/TMX output is not supported.

Document types

The following document types are included in the current version of the DCEP corpus:

For details on the statistics on the DCEP, click here. The tables contain a summary of the corpus size in

  • Number of documents;
  • Number of words;
  • Number of unique words.

Words have been counted with the wc Unix utility after removing the mark-up. On the other hand, unique words have been counted on tokenised text whereby only words composed from alphabetical characters have been taken into consideration. The first Table presents figures per language and document type while the second one contains statistics per language pair.

DCEP is the largest single release of documents published by an institution of the European Union. It contains various document types in 23 languages (253 language pairs). Here are some statistics:

  • Total number of documents : 1.5 million;
  • Total number of words: 1.37 billion;
  • Total number of English segments: 7.7 million;
  • The best-represented language in terms of number of words is English (103,458,996);
  • French and Spanish miss less than 10%.

More statistics are available in the publication  DCEP - Digital Corpus of the European Parliament (LREC'2014).
