GlobalHealthAtlas Public Evaluator
The GlobalHealthAtlas Public Evaluator is a fine-tuned version of Qwen3-8B (via LoRA) designed to assess Large Language Model (LLM) outputs along six critical dimensions of public health reasoning: Accuracy, Reasoning, Completeness, Consensus Alignment, Terminology Norms, and Insightfulness.
Model Description
This model acts as a domain-aligned evaluator distilled from high-confidence judgments of diverse LLMs. It is intended to be used as a ranking/scoring component for the GlobalHealthAtlas project, enabling reproducible evaluation of LLMs for safety-critical public health reasoning.
Intended Uses & Limitations
This model is intended to be used as a scoring component (scorer) for public health tasks, such as:
- Relevancy scoring of health documents.
- Automated quality assessment of reasoning chains.
- Content prioritization in public health contexts.
Disclaimer: This model is NOT intended for clinical diagnosis, medical advice, or other high-stakes decision-making. Users should validate performance on their own data prior to deployment.
Usage
To use the GlobalHealthAtlas Public Evaluator, clone the official repository and follow the instructions in the codebase.
Example: Running the Scorer
1cd scoring
2python scorer.py --input-file ../data/input.json --output-file ../data/output.json
Batch Scoring
1cd "Source Code/Public Evaluator"
2python scorer_batch.py
