Can a Suit of Armor Conduct Electricity? A New Dataset for Open Book Question Answering
https://arxiv.org/pdf/1809.02789.pdf

OpenBookQA is a question-answering dataset modeled after open book exams for
assessing human understanding of a subject. It consists of 5,957 multiple-choice
elementary-level science questions (4,957 train, 500 dev, 500 test), which probe
the understanding of a small “book” of 1,326 core science facts and the application
of these facts to novel situations. For training, the dataset includes a mapping
from each question to the core science fact it was designed to probe. Answering
OpenBookQA questions requires additional broad common knowledge, not contained
in the book. The questions, by design, are answered incorrectly by both a retrieval-
based algorithm and a word co-occurrence algorithm.
