摘要:

近年来,从阅读理解、语义角色标注甚至机器翻译到图像和视频理解,作为问答的任务和数据集急剧扩展。随着这种扩展,对“问答“本身的效用和定义有许多不同的看法。有些人认为它的范围应该是窄的,或者是宽的,或者它在今天的数据集中被过度使用。在这篇观点文章中,我们认为问答应该被认为是一种有时对研究特定现象有用的格式,而不是一种现象或任务本身。我们讨论了什么时候一个任务被正确地描述为问答,什么时候一个任务被有效地设置为问答,而不是使用其他格式。

英文摘要:

Recent years have seen a dramatic expansion of tasks and datasets posed as question answering, from reading comprehension, semantic role labeling, and even machine translation, to image and video understanding. With this expansion, there are many differing views on the utility and definition of "question answering" itself. Some argue that its scope should be narrow, or broad, or that it is overused in datasets today. In this opinion piece, we argue that question answering should be considered a format which is sometimes useful for studying particular phenomena, not a phenomenon or task in itself. We discuss when a task is correctly described as question answering, and when a task is usefully posed as question answering, instead of using some other format.
