  • Description:

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. Information retrieval is used to obtain relevant text from a large text corpus of web sentences, and these sentences are used as a premise P. The annotation of such premise-hypothesis pair is crowdsourced 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.
