Birds have four legs?! NumerSense: Probing Numerical Commonsense Knowledge of Pre-Trained Language Models

Recent works show that pre-trained language models (PTLMs), such as BERT, possess certain commonsense and factual knowledge. They suggest that it is promising to use PTLMs as "neural knowledge bases" via predicting masked words. Surprisingly, we find that this may not work for numerical commonsense ... View More
