## Model Details

This is a RoBERTa model trained from scratch on medieval texts. The model is intended to be used as a fondation for other ML tasks on NLP and HTR environments.

The train dataset entails 650M of tokens coming from texts on classical and medieval latin; old french and old Spanish from a period ranging from 5th BC to 16th centuries.

Several big corpora were cleaned and transformed to be used during the training process :

| dataset        | size          | Lang  | dates  |
| ------------- |:-------------:| -----:|-----:|
| CC100 [1]     | 3,2Gb | la | 5th BC - 18th|
| Corpus Corporum [2]    | 3,0Gb      |   la | 5th BC - 16th |
| CEMA [3] | 320Mb      |  la+fro   |9th - 15th |
| HOME-Alcar [4] | 38Mb     |  la+fro   | 12th - 15th |
| BFM [5] | 34Mb      |  fro   | 13th - 15th|
| AND [6] | 19Mb      |  fro   | 13th - 15th|
| CODEA [7] | 13Mb      |  spa   |12th - 16th |
|  | ~6,5Gb      |    |
|  | 650M tokens (4,5Gb)*     |   | |


* A significant overlapped quantity of text was detected across the corpora, specially on medieval collections. Besides, synthetic text ("Lorem ipsum dolorem...") was iteratively deleted.
