  • Description:

MC-TACO is a dataset of 13k question-answer pairs that require temporal commonsense comprehension. The dataset contains five temporal properties:

  1. duration (how long an event takes)
  2. temporal ordering (typical order of events)
  3. typical time (when an event occurs)
  4. frequency (how often an event occurs)
  5. stationarity (whether a state is maintained for a very long time or indefinitely)

We hope that this dataset can promote the future exploration of this particular class of reasoning problems.
