# CaseReportBench: Clinical Dense Extraction Benchmark

**CaseReportBench** is a curated benchmark dataset designed to evaluate how well large language models (LLMs) can perform **dense information extraction** from **clinical case reports**, with a focus on **rare disease diagnosis**.

It supports fine-grained, system-level phenotype extraction and structured diagnostic reasoning — enabling model evaluation in real-world medical decision-making contexts.

## 🔔 Note

This dataset accompanies our upcoming publication:

> **Zhang et al. CaseReportBench: An LLM Benchmark Dataset for Dense Information Extraction in Clinical Case Reports.**  
> *To appear in the Proceedings of the Conference on Health, Inference, and Learning (CHIL 2025), PMLR.*

The official PMLR citation and link will be added upon publication.

## Key Features

- **Expert-annotated**, system-wise phenotypic labels mimicking clinical assessments
- Based on real-world **PubMed Central-indexed clinical case reports**
- Format: JSON with structured head-to-toe organ system outputs
- Designed for: Biomedical NLP, IE, rare disease reasoning, and LLM benchmarking
- Metrics include: Token Selection Rate, Levenshtein Similarity, Exact Match
