Researchers have developed a new framework called Grounded Optimization to address hallucination issues in Large Language Models (LLMs) when applied to automated personal document rewriting, such as resumes. This five-layer framework incorporates temporal context validation, deterministic contamination detection, structural invariant enforcement, prompt-level grounding, and an evaluator agent. Experiments showed a significant reduction in hallucinations, with overall detected hallucination rates falling to 0.04-0.24 per resume, and temporal hallucinations reduced by 50-95%. The study also released its contamination taxonomy, evaluation code, and data, with prompt-level grounding alone proving effective for certain models and conditions. AI
