✨ bert-restore-punctuation
This a bert-base-uncased model finetuned for punctuation restoration on
Yelp Reviews.
The model predicts the punctuation and upper-casing of plain, lower-cased text. An example use case can be ASR output. Or other cases when text has lost punctuation.
This model 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.
Model restores the following punctuations -- [! ? . , - : ; ' ]
The model also restores the upper-casing of words.
🚋 Usage
Below is a quick way to get up and running with the model.
- First, install the package.
- Sample python code.
1from rpunct import RestorePuncts
2# The default language is 'english'
3rpunct = RestorePuncts()

This model works on arbitrarily large text in English language and uses GPU if available.
📡 Training data
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.
🎯 Accuracy
The fine-tuned model obtained the following accuracy on 45,990 held-out text samples:
