CECOR: Correction-oriented synthetic data construction for factual error correction

Chenyang Wang, Dongxiao He, Jianbiao Yang, Jianwu Dang, Lei Zhu, Longbiao Wang, Xiaobao Wang

CECoR corrects multi-hop factual errors by decomposing claims into steps and injecting perturbations to synthesize training data.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

CECoR achieves strong performance on multi-hop benchmarks, outperforming both distantly supervised methods and few-shot LLM baselines. It also generalizes effectively to single-hop correction and remains stable under noisy evidence.

C2weakest assumption

The assumption that controlled perturbations injected after decomposition produce high-quality, realistic training pairs that faithfully represent the distribution of real semantic errors in multi-hop claims.

C3one line summary

CECoR decomposes multi-hop claims into steps, synthesizes training pairs via perturbation injection, and uses supervised fine-tuning plus reinforcement learning to improve factual error correction on multi-hop benchmarks.
