# Dataset Card for "nllb-200-10M-sample"

This is a sample of nearly 10M sentence pairs from the [NLLB-200](https://arxiv.org/abs/2207.04672) 
mined dataset [allenai/nllb](https://huggingface.co/datasets/allenai/nllb), 
scored with the model [facebook/blaser-2.0-qe](https://huggingface.co/facebook/blaser-2.0-qe) 
described in the [SeamlessM4T](https://arxiv.org/abs/2308.11596) paper.

The sample is not random; instead, we just took the top `n` sentence pairs from each translation direction.
The number `n` was computed with the goal of upsamping the directions that contain underrepresented languages.
Nevertheless, the 187 languoids (language and script combinations) are not represented equally,
with most languoids totaling 36K to 200K sentences.
Over 60% of the sentence pairs have BLASER-QE score above 3.5.

This dataset can be used for fine-tuning massively multilingual translation models. 
We suggest the following scenario:
- Filter the dataset by the value of `blaser_sim` (the recommended threshold is 3.0 or 3.5);
- Randomly swap the source/target roles in the sentence pairs during data loading;
- Use that data to augment the dataset while fine-tuning an NLLB-like model for a new translation direction,
in order to mitigate forgetting of all the other translation directions.

The dataset is released under the terms of [ODC-BY](https://opendatacommons.org/licenses/by/1-0/). 
By using this, you are also bound to the respective Terms of Use and License of the original source.
