Introduced by Holger Schwenk et al. in A Corpus for Multilingual Document Classification in Eight Languages1 Jan 2018 archive 2025-07-28

Multilingual Document Classification Corpus (MLDoc) is a cross-lingual document classification dataset covering English, German, French, Spanish, Italian, Russian, Japanese and Chinese. It is a subset of the Reuters Corpus Volume 2 selected according to the following design choices:

  • uniform class coverage: same number of examples for each class and language,
  • official train / development / test split: for each language a training data of different sizes (1K, 2K, 5K and 10K stories), a development (1K) and a test corpus (4K) are provided (with exception of Spanish and Russian with 9458 and 5216 training documents respectively.
