# Portuguese punctuation and capitalisation restoration model
## Details of the model
This is a reduced version of the Portuguese capitalisation and punctuation restoration model developed by [VÓCALI](https://www.vocali.net) as part of the SANIVERT project.
You can try the model in the following [SPACE](https://huggingface.co/spaces/VOCALINLP/punctuation_and_capitalization_restoration_sanivert)
## Details of the dataset
This a neuralmind/bert-base-portuguese-cased model fine-tuned for punctuation restoration using the following data distribution.
| Language | Number of text samples | Number of tokens |
| -------- | ---------------------- | ---------------- |
| Portuguese | 2,974,058 | 49,720,263 |
## Evaluation Metrics
The metrics used to the evaluation of the model are the Macro and the Weighted F1 scores.
## Funding
This work was funded by the Spanish Government, the Spanish Ministry of Economy and Digital Transformation through the Digital Transformation through the "Recovery, Transformation and Resilience Plan" and also funded by the European Union NextGenerationEU/PRTR through the research project 2021/C005/0015007
## How to use the model
The metrics used to the evaluation of the model are the Macro and the Weighted F1 scores.
