Denny asked: Test for natural language inference.
Premise: "A firefighter is taking off his mask."
Hypothesis: "A firefighter just left a burning building."
Is the hypothesis entailed by the premise?
Options:
- yes
- no
- it is not possible to tell.
Le: OK, so how can I answer with some explanation?
A firefighter taking off his mask has not necessarily just left a burning building. He may have been trying on the mask or wearing it for a training exercise.
The answer: it is not possible to tell.
