摘要:

我们介绍了NewsQA,这是一个具有挑战性的机器理解数据集,包含超过100,000个人类生成的问答对。Crowdworker根据CNN的1万多篇新闻文章提供问题和答案,答案由相应文章的文本组成。我们通过一个四阶段的过程来收集这个数据集,该过程旨在征求需要推理的探索性问题。一个彻底的分析证实,NewsQA需要的能力不仅仅是简单的词匹配和识别文本蕴涵。我们在数据集上测量人类的表现,并将其与几个强大的神经模型进行比较。人类和机器之间的性能差距(F1为0.198)表明,通过未来的研究,NewsQA可以取得重大进展。该数据集可在https://datasets.maluuba.com/NewsQA上免费获得。

英文摘要:

We present NewsQA, a challenging machine comprehension dataset of over 100,000 human-generated question-answer pairs. Crowdworkers supply questions and answers based on a set of over 10,000 news articles from CNN, with answers consisting of spans of text from the corresponding articles. We collect this dataset through a four-stage process designed to solicit exploratory questions that require reasoning. A thorough analysis confirms that NewsQA demands abilities beyond simple word matching and recognizing textual entailment. We measure human performance on the dataset and compare it to several strong neural models. The performance gap between humans and machines (0.198 in F1) indicates that significant progress can be made on NewsQA through future research. The dataset is freely available at https://datasets.maluuba.com/NewsQA.
