MultiUN

This is a collection of translated documents from the United Nations originally compiled by Andreas Eisele and Yu Chen (see http://www.euromatrixplus.net/multi-un/). Please cite MultiUN: A Multilingual corpus from United Nation Documents, Andreas Eisele and Yu Chen, LREC 2010

7 languages, 21 bitexts
total number of files: 420,404
total number of tokens: 1.64G
total number of sentence fragments: 69.30M

Bottom-left triangle: download files
  • ces = sentence alignments in XCES format
  • leftmost column language IDs = corpus files in XML
  • TMX and plain text files (Moses): see "Statistics" below
  • lower row language IDs = parsed corpus files (if they exist)
Upper-right triangle: sample files
  • view = bilingual XML file samples
  • upper row language IDs = monolingual XML file samples
  • rightmost column language IDs = parsed XML file samples (if they exist)

Statistics and TMX/Moses Downloads

Number of files, tokens, and sentences per language (including non-parallel ones if they exist)
Number of sentence alignment units per language pair

Upper-right triangle: download translation memory files (TMX)
Bottom-left triangle: download plain text files (MOSES/GIZA++)

Note that TMX files only contain unique translation units and, therefore, the number of aligned units is smaller than for the distributions in Moses and XML format. Moses downloads include all non-empty alignment units including duplicates. Token counts for each language also include duplicate sentences and documents.
