Grammatical Error Correction

Ask about this topic

Overview

Grammatical error correction studies how to identify and fix errors in written or spoken language while preserving the writer’s intended meaning. Common approaches include neural sequence-to-sequence models trained on parallel or synthetically corrupted text, as well as large language models guided by prompts, retrieval, fine-tuning, or reinforcement learning. Systems are tested on benchmarks such as CoNLL-2014 and BEA-2019, with growing work on multilingual, low-resource, spoken, and domain-specific settings. A central challenge is balancing precision and minimal edits against fluency: systems must avoid over-correction, handle valid alternatives that differ from a reference, and provide reliable evaluation and useful feedback.
