# Data cleanup

Need better data filtering:
* integrate OpusFilter
* Tatoeba MT challenge data sets are noisy for smaller languages like Breton (but the similarity scores are not available), CC-Matrix etc is not very good for those languages
* cleanup script also before subword splitting?
* stronger filters in cleanup script?
* idea: compare character diversity between the two languages and use a threshold to filter sentences? (language-specific?)
