摘要:

对于一个在研究中有用的自然语言理解基准,它必须包含足够多样和困难的示例,以区分当前和不久的将来的最先进的系统。然而,我们还不知道如何最好地选择文本源来收集各种具有挑战性的例子。在这项研究中,我们众包多项选择阅读理解问题的段落从七个不同的质量来源,分析哪些属性的段落有助于收集的例子的难度和问题类型。令我们惊讶的是,我们发现文章来源,长度和可读性的措施并没有显着影响问题的难度。通过我们对七种推理类型的人工注释,我们观察到段落来源和推理类型之间的几个趋势,例如,在为技术文章而写的问题中,逻辑推理往往是需要的。这些结果表明,当创建一个新的基准数据集时,选择一组不同的段落可以帮助确保不同的问题类型,但段落难度不需要优先考虑。

英文摘要:

For a natural language understanding benchmark to be useful in research, it has to consist of examples that are diverse and difficult enough to discriminate among current and near-future state-of-the-art systems. However, we do not yet know how best to select text sources to collect a variety of challenging examples. In this study, we crowdsource multiple-choice reading comprehension questions for passages taken from seven qualitatively distinct sources, analyzing what attributes of passages contribute to the difficulty and question types of the collected examples. To our surprise, we find that passage source, length, and readability measures do not significantly affect question difficulty. Through our manual annotation of seven reasoning types, we observe several trends between passage sources and reasoning types, e.g., logical reasoning is more often required in questions written for technical passages. These results suggest that when creating a new benchmark dataset, selecting a diverse set of passages can help ensure a diverse range of question types, but that passage difficulty need not be a priority.
