# SMOL

SMOL (Set for Maximal Overall Leverage) is a collection professional
translations into 115 Low-Resource Languages, for the purpose of training
translation models, and otherwise increasing the representations of said
languages in NLP and technology.

Please read our [paper](...) for a much more thorough description!

## Resources in this repository

There are three resources in this directory:

*   **SmolSent:** A collection of sentence-level translations into 81 languages
*   **SmolDoc:** A collection of document-level translations into 100 languages
*   **SmolDoc-factuality-annotations:** A collection of sentence-level
    translations into 81 languages

## Per-language information

The following table only includes information for the
`source_lang_translated_lang` direction. However, data in this repo is released
in both directions, so e.g. this table lists only `en_ay`, but reversed `ay_en`
data is also released.

## Notes on language codes

We use the backwards-compatible BCP-47 language code convention. Several of
these languages have various alternate code also in use, including:

*   **ak** Twi also uses the code `tw`. Note that using the supercode for the
    most prevelent language variety is very common, e.g. `ku` for `kmr`, `zh`
    for `cmn`, etc.
*   **ber** The grouping of the Tamazight languages is a matter of debate. The
    variety in these data is probably close to `tzm`, though a language expert
    should opine
*   **qu** Another supercode issue. The Quechua variety this data is closest to
    is likely `quy`, though a language expert should opine
*   **pa-Arab** is also referred to as `lah`

For convenience, here is a mapping from codes used by Flores and SMOL:

## Known issues

There are several known issues of this dataset:

*   The translations of `SmolDoc` to Ho (Warang Citi script) (`hoc`) contain
    some instances of transliterated English, rather than actual Ho text. This
    is currently being corrected.
*   The translations to Mooré (`mos`) contain a mix of orthographies.
*   The translations into Kituba (`ktu`), Tulu (`tcy`), Nepali (`ne`), and
    Tibetan (`bo`) caused notable regressions in `ChrF`, suggesting that they
    are low-quality, though this could also be an issue with training or
    evaluation.

If you speak any of these languages and notice quality issues, please reach out.
Another especially useful piece of information is whether the correct
orthographies are used in these deliveries.
