+### [Dataset Summary](#dataset-summary)
+
+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
