AtomEval: Validity-Aware Atomic Evaluation of Adversarial Claim Rewriting in Fact Verification

Hanze Jia, Hongyi Cen, Jingyi Zheng, Mingxin Wang, Tan Tang, Yule Liu

AtomEval evaluates adversarial claims by decomposing them into atomic SROM components to better detect factual corruptions.

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

Experiments on the FEVER dataset across representative attack strategies and LLM generators show that AtomEval provides more reliable evaluation signals in our experiments.

C2weakest assumption

That decomposing claims into SROM atoms and applying Atomic Validity Scoring accurately captures truth-conditional consistency and detects factual corruption without introducing its own biases or missing key semantic nuances.

C3one line summary

AtomEval introduces atomic claim decomposition and validity scoring to provide more reliable evaluation of adversarial rewrites than standard similarity metrics in fact verification.
