The SciTail dataset is an entailment dataset created from multiple-choice science exams and
web sentences. Each question and the correct answer choice are converted into an assertive
statement to form the hypothesis. We use information retrieval to obtain relevant text from
a large text corpus of web sentences, and use these sentences as a premise P. We crowdsource
the annotation of such premise-hypothesis pair as supports (entails) or not (neutral), in order
to create the SciTail dataset. The dataset contains 27,026 examples with 10,101 examples with
entails label and 16,925 examples with neutral label.
