natgillin/translations

Parquet bitext corpus assembled from upstream mtdata / OPUS releases.

Schema

column	type	description
source	string	source-language sentence
target	string	target-language sentence
source_lang	string	source language, ISO 639-3 (3-char), e.g. bel, cat, eng
target_lang	string	target language, ISO 639-3 (3-char)
origin	string	upstream sub-corpus, e.g. opus-ccmatrix, opus-nllb, elr, mtdata-merged

Source / target ordering is fixed by alphabetical ISO 639-3 code (bel before eng, cat before eng). This keeps the pair name deterministic and bidirectional joins unambiguous.

Configs / layout

One config per language pair. The OPUS sub-corpus is encoded as a row-level column (origin), not as a separate config.

data/
  bel-eng/
    opus-ccmatrix-00000-of-00200.parquet
    opus-nllb-00000-of-00200.parquet
    mtdata-merged-00000-of-00200.parquet
    ...
  cat-eng/
    ...

configs: is left empty in the frontmatter; HF auto-discovers a per-directory config from data/<pair>/*.parquet.

origin values

value	meaning
mtdata-merged	mtdata's final deduplicated merged bitext for the pair
opus-<source>	one upstream OPUS sub-corpus, e.g. opus-ccmatrix, opus-nllb, opus-ccaligned, opus-multiccaligned, opus-wikimatrix, opus-eubookshop, opus-kde4, opus-gnome, opus-neulab-tedtalks, ...
elr	ELRA / ELR slice of the pair when distinct from the merged top-level
