Do Grammatical Error Correction Models Realize Grammatical Generalization? (2021.findings-acl)
Copied to clipboard
| Challenge: | Existing models for grammatical error correction use pseudo data, but they are inconvenient for realworld deployment due to large amounts of training data. |
| Approach: | They propose a method to evaluate whether GEC models can generalize to unseen errors by using synthetic and real GEC datasets with controlled vocabularies. |
| Outcome: | The proposed model fails to realize grammatical generalization even in simple settings with limited vocabulary and syntax, suggesting it lacks the generalization ability required to correct errors from provided training examples. |
