+### [Dataset Summary](#dataset-summary)
+
+OpenBookQA aims to promote research in advanced question-answering, probing a deeper understanding of both the topic
+(with salient facts summarized as an open book, also provided with the dataset) and the language it is expressed in. In
+particular, it contains questions that require multi-step reasoning, use of additional common and commonsense knowledge,
+and rich text comprehension.
+OpenBookQA is a new kind of question-answering dataset modeled after open book exams for assessing human understanding of
+a subject.
