 #### Preprocessing
 
-After concatenation, all datasets are cleaned and deduplicated using [bifixer](https://github.com/bitextor/bifixer) and [biclener](https://github.com/bitextor/bicleaner) tools [(Ramírez-Sánchez et al., 2020)](https://aclanthology.org/2020.eamt-1.31/). Any sentence pairs with a classification score of less than 0.5 is removed. The filtered corpus is composed of 9,033,998 parallel sentences.

Any sentence pairs with a LaBSE similarity score of less than 0.5 is removed.  The filtered corpus is composed of 9,033,998 parallel sentences.
 
 #### Tokenization
 All data is tokenized using sentencepiece, with a 32,000 token sentencepiece model learned from the combination of all filtered training data. This model is included.
