摘要:

数据增强最近在NLP中引起了越来越多的兴趣,这是由于在低资源领域的更多工作、新任务以及需要大量训练数据的大规模神经网络的流行。尽管最近出现了这种激增,但这一领域的探索仍然相对不足,这可能是由于语言数据的离散性带来的挑战。在本文中,我们提出了一个全面和统一的调查数据增强的NLP通过总结文献结构化的方式。我们首先介绍和激励自然语言处理的数据增强,然后讨论主要的方法论代表性的方法。接下来,我们将重点介绍用于流行的NLP应用程序和任务的技术。最后,我们概述了当前的挑战和未来的研究方向。总的来说,我们的论文旨在澄清现有文献中的自然语言处理数据增强的景观,并激励在这一领域的额外工作。我们还提供了一个GitHub存储库和一个纸质列表,该列表将在https://github.com/styfeng/DataAug4NLP上不断更新。

英文摘要:

Data augmentation has recently seen increased interest in NLP due to more work in low-resource domains, new tasks, and the popularity of large-scale neural networks that require large amounts of training data. Despite this recent upsurge, this area is still relatively underexplored, perhaps due to the challenges posed by the discrete nature of language data. In this paper, we present a comprehensive and unifying survey of data augmentation for NLP by summarizing the literature in a structured manner. We first introduce and motivate data augmentation for NLP, and then discuss major methodologically representative approaches. Next, we highlight techniques that are used for popular NLP applications and tasks. We conclude by outlining current challenges and directions for future research. Overall, our paper aims to clarify the landscape of existing literature in data augmentation for NLP and motivate additional work in this area. We also present a GitHub repository with a paper list that will be continuously updated at https://github.com/styfeng/DataAug4NLP
