rpunct - Restore Punctuation
This repo contains code for Punctuation restoration.
This package is intended for direct use as a punctuation restoration model for the general English language. Alternatively, you can use this for further fine-tuning on domain-specific texts for punctuation restoration tasks. It uses HuggingFace's bert-base-uncased model weights that have been fine-tuned for Punctuation restoration.
Punctuation restoration works on arbitrarily large text. And uses GPU if it's available otherwise will default to CPU.
List of punctuations we restore:
- Upper-casing
- Period: .
- Exclamation: !
- Question Mark: ?
- Comma: ,
- Colon: :
- Semi-colon: ;
- Apostrophe: '
- Dash: -
🚀
Usage
Below is a quick way to get up and running with the model.
- First, install the package.
pip install rpunct
- Sample python code.
from rpunct import RestorePuncts
# The default language is 'english'
rpunct = RestorePuncts()
rpunct.punctuate("""in 2018 cornell researchers built a high-powered detector that in combination with an algorithm-driven process called ptychography set a world record

Accuracy
Here is the number of product reviews we used for finetuning the model:
| Language | Number of text samples |
|---|---|
| English | 560,000 |
We found the best convergence around 3 epochs, which is what presented here and available via a download.
The fine-tuned model obtained the following accuracy on 45,990 held-out text samples:
| Accuracy | Overall F1 | Eval Support |
|---|---|---|
| 91% | 90% | 45,990 |
