About this paper

Xin Li, Jin Li, Shoujin Wang, Kun Yu, Fang Chen

DKCD uses domain knowledge to help an LLM identify implicit clinical factors and guide annotation before statistical causal graph discovery. On synthetic Respiratory descriptions, with GPT-4o, it achieved node F1 of 0.74 and adjacency F1 of 0.68, compared with COAT’s 0.29 and 0.15, respectively. Its ESHD was 16.67 versus 27.00. Both datasets are synthetic, so real-world clinical effectiveness remains unestablished.
