+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.
