摘要:

我们提出了一个两阶段的神经模型来解决从文档中生成问题。首先,我们的模型通过在问答语料库中的答案上训练神经关键短语提取器来估计文档中的单词序列是人类在选择候选答案时会选择的单词序列的概率。预测的关键短语,然后作为目标答案和条件的序列到序列的问题生成模型与复制机制。从经验上讲,我们的关键短语提取模型显着优于实体标记基线和现有的基于规则的方法。我们进一步证明,我们的问题生成系统制定流畅,回答问题的关键短语。这个两阶段系统可用于增强或生成阅读理解数据集,这些数据集可用于改善机器阅读系统或教育环境。

英文摘要:

We propose a two-stage neural model to tackle question generation from documents. First, our model estimates the probability that word sequences in a document are ones that a human would pick when selecting candidate answers by training a neural key-phrase extractor on the answers in a question-answering corpus. Predicted key phrases then act as target answers and condition a sequence-to-sequence question-generation model with a copy mechanism. Empirically, our key-phrase extraction model significantly outperforms an entity-tagging baseline and existing rule-based approaches. We further demonstrate that our question generation system formulates fluent, answerable questions from key phrases. This two-stage system could be used to augment or generate reading comprehension datasets, which may be leveraged to improve machine reading systems or in educational settings.
