Explainable Numerical Claim Verification
The rapid proliferation of mis- and disinformation in the digital age highlights the urgent need for scalable, transparent, and trust-worthy automated fact-checking systems. Large Language Models (LLMs) offer strong language understanding capabilities but suf-fer from opacity and brittleness, particularly in reasoning over numerical claims. This work explores how Explainable Artificial Intelligence (XAI)—through the lens of counterfactual explanations and adversarial training—can be used to systematically evaluate and improve the robustness of LLMs against perturbed numerical inputs. We propose a framework that employs counterfactual gen-eration to both probe LLM reliability and generate user-appropriate explanations. Through empirical evaluations using a large-scale numerical fact-checking dataset (QuanTemp), we show that even state-of-the-art LLMs are susceptible to subtle numerical pertur-bations, impacting verdict accuracy. Our methodology contributes a dual-purpose diagnostic and training strategy that not only bol-sters robustness but also enables both global and local interpretabil-ity—thereby improving explainability in automated fact-checking systems.
Boosting Trust in AI Fact-Checking
This research addresses the critical need for robust and transparent automated fact-checking systems, particularly concerning numerical claims. It highlights the brittleness of current LLMs to subtle numerical perturbations and proposes leveraging Explainable AI (XAI) through counterfactual explanations and adversarial training to enhance reliability and interpretability. The framework offers a dual-purpose diagnostic and training strategy, aiming to improve LLM accuracy and provide clear explanations for users.

Case Study: Financial Reporting Verification
A financial news outlet used an LLM-based fact-checker. An article stated 'Company X reported $5 million in Q4 revenue.' Due to a subtle perturbation where the article changed it to 'Company X reported about $5 million in Q4 revenue,' the LLM incorrectly flagged it as 'TRUE' even when evidence showed exactly '$5,000,000' and no 'about'. This led to a brief period of inaccurate reporting until human intervention corrected the subtle error, demonstrating the challenge numerical perturbations pose for LLM accuracy.
Key Takeaway: Subtle phrasing changes around numerical values can severely impact LLM accuracy, necessitating robust perturbation handling and explainability features.
