RICE: Reasoning-integrated correction evolution for Chinese grammatical error correction
摘要
Chinese grammatical error correction remains challenging due to flexible word order, implicit morphology, and the need for context-dependent reasoning. Most methods still treat correction as a direct sequence transformation and learn to mimic edits without understanding why they are correct, which leads to spurious modifications and unstable performance across diverse grammatical patterns. This paper introduces RICE, a reasoning-integrated framework that models correction as a reasoning-conditioned decision process. RICE employs multi-agent reflective distillation to acquire structured grammatical cognition, reasoning-mediated decoder integration to inject explanatory signals into edit generation, and self-evolving reinforcement to refine edit reliability under imperfect supervision. Experiments on two public datasets show that RICE achieves competitive precision-oriented correction performance. These results demonstrate the benefit of aligning reasoning trajectories with correction behavior and support a shift toward reasoning-centered grammatical error correction.
