A Role-Based LLM Framework for Structured Information Extraction from Healthy Food Policies

Dimensions overall score 7.0

• Current LLM approaches for information extraction in healthy food policy are hindered by misinformation including hallucinations, misclassifications, and omissions.limitation 90%
  Evidencepartial

  Current Large Language Model (LLM) approaches for information extraction (IE) in the healthy food policy domain are often hindered by various factors, including misinformation, specifically hallucinations, misclassifications, and omissions

  Evidencepartial

  this study proposes a role-based LLM framework that automates the IE from unstructured policy data by assigning specialized roles: an LLM policy analyst for metadata and mechanism classification, an LLM legal strategy specialist for identifying complex legal approaches, and an LLM food system expert for categorizing food system stages
