EpiNarrate: Agentic Generation of Grounded Narratives from Epidemiological Scenario Projections

Short summary

EpiNarrate is an agentic framework that generates grounded public health narratives from epidemiological projection data by separating structured numerical reasoning from natural-language generation. It organizes scenario axes into a partial-order schema, derives valid quantitative statements through a comparison grammar, and uses maximum-entropy-based interestingness selection to balance coverage and non-redundancy. Experiments on COVID-19 Scenario Modeling Hub data show improved factual grounding and broader coverage compared to direct LLM summarization.

  • EpiNarrate separates numerical reasoning from NL generation to produce grounded epidemiological narratives
  • Uses partial-order schema and comparison grammar to enforce semantic and arithmetic consistency
  • Maximum-entropy interestingness selection balances coverage and non-redundancy; validated on COVID-19 Scenario Modeling Hub
