This is a [bert-base-portuguese-cased](https://huggingface.co/neuralmind/bert-base-portuguese-cased) model finetuned for punctuation restoration on [WikiLingua](https://github.com/esdurmus/Wikilingua). 

This model is intended for direct use as a punctuation restoration model for the general Portuguese language. Alternatively, you can use this for further fine-tuning on domain-specific texts for punctuation restoration tasks.

Model restores the following punctuations -- **[! ? . , - : ; ' ]**

The model also restores the upper-casing of words.

-----------------------------------------------

## 🤷 Usage

🇧🇷 easy-to-use package to restore punctuation of portuguese texts.

**Below is a quick way to use the template.**

1. First, install the package.

```
pip install respunct
```

2. Sample python code.

``` python
from respunct import RestorePuncts

model = RestorePuncts()

model.restore_puncts("""
henrique foi no lago pescar com o pedro mais tarde foram para a casa do pedro fritar os peixes""")
# output:
# Henrique foi no lago pescar com o Pedro. Mais tarde, foram para a casa do Pedro fritar os peixes.

```
