| # 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/ |
| ... |
| ``` |
|
|
| Each language pair is one config (`bel-eng`, `cat-eng`) with everything |
| under that pair pinned to `split: train`. The configs are listed |
| explicitly in the YAML frontmatter so that HF's auto-split detection |
| does not mistake filenames containing substrings like `-test-` for an |
| actual test split. |
|
|
| ## `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 | |
