01 / MOTIVATION

Why this work matters

Numerical fact-checking calls for comparisons between prompts and targeted adaptation rather than assuming a general-purpose model is sufficient.

A comparison of prompted and fine-tuned language models for numerical claim verification.

02 / METHODOLOGY

Research approach

The paper compares prompted and fine-tuned language models for classifying numerical claims.

Simplified comparison of independent ClaimIQ approaches: selected evidence is used with zero-shot prompted LLaMA or fine-tuned LoRA LLaMA and RoBERTa models, each predicting True, False or Conflicting.
