CHARD: Clinical Health-Aware Reasoning Across Dimensions for Text Generation Models (2023.eacl-main)
Copied to clipboard
| Challenge: | Existing studies show that pretrained language models can act as knowledge bases and reason like humans. |
| Approach: | They propose to use pretrained language models to generate free-flow textual explanations about 52 health conditions across three clinical dimensions. |
| Outcome: | The proposed model can generate concise and readable text, but can be improved on medical accuracy and QA. |
MIMICause: Representation and automatic extraction of causal relation types from clinical notes (2022.findings-acl)
Copied to clipboard
| Challenge: | Extracted causal information from clinical notes can be combined with structured EHR data such as demographics, diagnoses, and medications. |
| Approach: | They propose to annotate clinical notes and develop an annotated corpus and provide baseline scores to identify types and direction of causal relations between a pair of biomedical concepts. |
| Outcome: | The proposed annotation guidelines achieved a high inter-annotator agreement and a macro F1 score on the clinical text. |
