Comparison of the Evaluation Metrics for Neural Grammatical Error Correction With Overcorrection

Abstract: Grammar error correction (GEC) refers to the proper correction of grammatical errors in a given sentence. Important factors to consider in GEC are not only the grammatical correction of the sentence, but also the recognition of a correct sentence in which no changes are required. However, GEC approaches in which deep learning recently started being used consider only the former aspect, which leads to overcorrection, whereby changes are made to a correct sentence unnecessarily. Because this bias is also reflect… Show more

“…Park et al adopted the parallel structure of multiple models and used three kinds of models based on rules, statistics, and neural networks. First, they made low-level combination within categories to get category candidates and then made high-level combination of category candidates [ 20 ].…”

“…The reason for choosing the commercialization system for comparison is that it is a certified system used by several researchers, and the latest deep learning-based grammatical correction methodology is applied; hence, it is the most objective and reliable system for accurate analysis. The performance of each corrector is measured by using the error sentences of K-NCT as input for three commercialization systems and performing quantitative analysis using the BLEU score [20] and GLEU score [21], which are used in various deep learning-based grammatical correction studies as evaluation indicators [1,22,23]. The experimental results are shown in Table 4.…”
