Token-Level Supervised Contrastive Learning for Punctuation Restoration

Huang, Qiushi, Ko, Tom, Tang, H Lilian et al.

Understand

Punctuation is critical in understanding natural language text.

  • Currently, most automatic speech recognition (ASR) systems do not generate punctuation, which affects the performance of downstream tasks, such as intent detection and slot filling.
  • This gives rise to the need for punctuation restoration.
  • Recent work in punctuation restoration heavily utilizes pre-trained language models without considering data imbalance when predicting punctuation classes.
