Alirector: Alignment-Enhanced Chinese Grammatical Error Corrector (2024.findings-acl)
Copied to clipboard
| Challenge: | Existing methods to address overcorrection in Chinese grammatical error correction (CGEC) are difficult to adapt to decoder-only large language models (LLMs). |
| Approach: | They propose an alignment-enhanced corrector for the overcorrection problem that applies to both Seq2Seq models and decoder-only large language models (LLMs). |
| Outcome: | The proposed corrector alleviates the overcorrection problem in Chinese grammatical error correction (CGEC) using generative models and decoder-only large language models. |
