摘要:

使用伪数据的语法错误纠正(GEC)的数据生成方法已经引起了越来越多的兴趣。然而,这些方法存在几个问题,使得它们不便于现实世界的部署,包括需要大量的训练数据。另一方面,如果GEC模型可以实现语法泛化,则一些基于语法规则的错误可能不一定需要大量的数据。本研究探讨GEC模型在多大程度上概括了纠正错误所需的语法知识。我们介绍了一种分析方法,使用合成和真实的GEC数据集与控制词汇,以评估模型是否可以推广到看不见的错误。我们发现,目前标准的基于transformer的GEC模型未能实现语法泛化,即使在简单的设置与有限的词汇和语法,这表明它缺乏所需的泛化能力,以纠正错误,从提供的训练样本。

英文摘要:

There has been an increased interest in data generation approaches to grammatical error correction (GEC) using pseudo data. However, these approaches suffer from several issues that make them inconvenient for real-world deployment including a demand for large amounts of training data. On the other hand, some errors based on grammatical rules may not necessarily require a large amount of data if GEC models can realize grammatical generalization. This study explores to what extent GEC models generalize grammatical knowledge required for correcting errors. We introduce an analysis method using synthetic and real GEC datasets with controlled vocabularies to evaluate whether models can generalize to unseen errors. We found that a current standard Transformer-based GEC model fails to realize grammatical generalization even in simple settings with limited vocabulary and syntax, suggesting that it lacks the generalization ability required to correct errors from provided training examples.
