✨ bert-restore-punctuation

forthebadge

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.


πŸš‹ Usage

Below is a quick way to get up and running with the model.

  1. First, install the package.
pip install rpunct
  1. 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

This model works on arbitrarily large text in English language and uses GPU if available.
