Causal Tree Extraction from Medical Case Reports: A Novel Task for Experts-like Text Comprehension (2025.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods to extract causal relationships from medical case reports are insufficient for capturing causal relationships of an entire case. |
| Approach: | They propose a task that generates a causal tree with the primary disease as the root and extracts causal relationships from a medical case report. |
| Outcome: | The proposed method outperforms the baseline method by 20.2 points in the human evaluation and introduces evaluation metrics that reflect clinician preferences. |
