摘要:

机器阅读理解(MRC)是自然语言处理(NLP)领域的一个长期研究课题。MRC任务旨在根据给定的上下文回答问题。最近的研究集中在多跳MRC,这是一个更具挑战性的扩展MRC,它回答一个问题,一些不相交的信息片段跨上下文需要。由于多跳MRC的复杂性和重要性,近年来有大量的研究集中在这一课题上,因此有必要对相关文献进行综述。本研究旨在基于2018年至2022年的31项研究,调查多跳MRC方法的最新进展。在这方面,首先,将介绍多跳MRC问题的定义,然后将详细审查31个模型,重点关注它们的多跳方面。他们也将根据他们的主要技术进行分类。最后,一个细粒度的全面比较的模型和技术。

英文摘要:

Machine reading comprehension (MRC) is a long-standing topic in natural language processing (NLP). The MRC task aims to answer a question based on the given context. Recently studies focus on multi-hop MRC which is a more challenging extension of MRC, which to answer a question some disjoint pieces of information across the context are required. Due to the complexity and importance of multi-hop MRC, a large number of studies have been focused on this topic in recent years, therefore, it is necessary and worth reviewing the related literature. This study aims to investigate recent advances in the multi-hop MRC approaches based on 31 studies from 2018 to 2022. In this regard, first, the multi-hop MRC problem definition will be introduced, then 31 models will be reviewed in detail with a strong focus on their multi-hop aspects. They also will be categorized based on their main techniques. Finally, a fine-grain comprehensive comparison of the models and techniques will be presented.
