论文摘要
问题生成(QG)是自动智能辅导系统的重要组成部分,该系统旨在产生高质量的问题,以促进阅读实践和评估。但是,现有的QG技术遇到了有关数据集的有偏见和不自然语言来源的几个关键问题,这些问题主要是从网络获得的(例如小队)。在本文中,我们提出了一种创新的考试类型问题生成方法(EQG-RACE),以根据从种族中提取的数据集生成类似检查的问题。 EQG-Race采用了两种主要策略来处理长篇小说之间的离散答案信息和推理。一个粗略的答案和关键句子标记方案用于增强输入的表示。答案引导的图形卷积网络(AG-GCN)旨在捕获结构信息,以揭示句子间和句子内关系。实验结果表明,EQG-Race的最新性能显然优于基线。此外,我们的工作已经建立了一个具有重塑数据集和QG方法的新QG原型,该原型为未来工作的相关研究提供了重要的基准。我们将使我们的数据和代码公开用于进一步研究。
Question Generation (QG) is an essential component of the automatic intelligent tutoring systems, which aims to generate high-quality questions for facilitating the reading practice and assessments. However, existing QG technologies encounter several key issues concerning the biased and unnatural language sources of datasets which are mainly obtained from the Web (e.g. SQuAD). In this paper, we propose an innovative Examination-type Question Generation approach (EQG-RACE) to generate exam-like questions based on a dataset extracted from RACE. Two main strategies are employed in EQG-RACE for dealing with discrete answer information and reasoning among long contexts. A Rough Answer and Key Sentence Tagging scheme is utilized to enhance the representations of input. An Answer-guided Graph Convolutional Network (AG-GCN) is designed to capture structure information in revealing the inter-sentences and intra-sentence relations. Experimental results show a state-of-the-art performance of EQG-RACE, which is apparently superior to the baselines. In addition, our work has established a new QG prototype with a reshaped dataset and QG method, which provides an important benchmark for related research in future work. We will make our data and code publicly available for further research.
