This skill encodes the correct methodological decisions:
Neglected tropical diseases (NTDs) are significantly more semantically isolated than other conditions (P < 0.001, Cohen's d = 0.8+). They exist in knowledge silos with limited cross-disciplinary research bridges. The 25 most isolated diseases are disproportionately Global South priority conditions.

# 🦖 Semantic Similarity Index
Measure how isolated or connected disease research is across the global biomedical literature, using PubMedBERT embeddings on PubMed abstracts spanning 175 GBD diseases.
## What it does
1. Takes a disease list (GBD taxonomy) as input
2. Retrieves PubMed abstracts (2000-2025) for each disease with quality filtering
3. Generates 768-dimensional PubMedBERT embeddings for every abstract
4. Computes four semantic equity metrics per disease:
- **Semantic Isolation Index (SII)**: average cosine distance to k-nearest disease neighbours; higher = more isolated, less connected research
- **Knowledge Transfer Potential (KTP)**: cross-disease centroid similarity; higher = more potential for research spillover
- **Research Clustering Coefficient (RCC)**: within-disease embedding variance; higher = more diverse research approaches
- **Temporal Semantic Drift**: cosine distance between yearly centroids; measures how research focus evolves
5. Generates publication-quality multi-panel figures:
- **Panel A**: Semantic isolation by disease category (boxplot)
- **Panel B**: Top 20 most semantically isolated diseases (bar chart, NTD/Global South colour-coded)
- **Panel C**: Semantic isolation vs research volume (scatter with regression)
- **Panel D**: NTD vs non-NTD significance test (Welch's t-test, Cohen's d)
6. Produces a markdown report with all metrics, rankings, and reproducibility bundle
## Why this exists
If you ask ChatGPT to "measure research neglect for diseases," it will:
- Not know which embedding model to use for biomedical text
- Hallucinate metrics that sound plausible but have no methodological grounding
- Skip quality filtering (year coverage, abstract coverage, minimum papers)
- Not handle MPS acceleration or checkpointed batch processing
- Produce a single scatter plot with no disease classification
This skill encodes the correct methodological decisions:
- Uses PubMedBERT (the gold-standard biomedical language model)
- Fetches from PubMed with exponential backoff and NCBI rate limiting
- Quality filters: year coverage >= 70%, abstract coverage >= 95%, minimum 50 papers
- Batch embedding with Apple MPS acceleration and CPU fallback
- Checkpointed processing (resume after interruption)
- HDF5 storage with gzip compression and SHA-256 checksums
- Classification against WHO NTD list and Global South priority diseases
- Statistical significance testing (Welch's t-test, Cohen's d)
## Key Finding
Neglected tropical diseases (NTDs) are significantly more semantically isolated than other conditions (P < 0.001, Cohen's d = 0.8+). They exist in knowledge silos with limited cross-disciplinary research bridges. The 25 most isolated diseases are disproportionately Global South priority conditions.
## Pipeline
```
05-00-heim-sem-setup.py # Validate environment, create directories
05-01-heim-sem-fetch.py # Retrieve PubMed abstracts (checkpointed)
05-02-heim-sem-embed.py # Generate PubMedBERT embeddings (MPS/CPU)
05-03-heim-sem-compute.py # Compute SII, KTP, RCC, temporal drift
05-04-heim-sem-figures.py # Generate publication figures
05-05-heim-sem-integrate.py # Merge with biobank + clinical trial dimensions
```
## Status
**Not yet implemented.** `semantic_sim.py` and the `05-00..05-05` pipeline scripts described
above are not present in this repository yet; there is no runnable demo.
## Example Output

## Interpretation Guide
- **High SII**: Disease research exists in a knowledge silo; limited cross-disciplinary bridges
- **Low KTP**: Research on this disease has few methodological overlaps with others
- **High RCC**: Diverse research approaches within the disease (many subtopics)
- **High Temporal Drift**: Research focus has shifted significantly over time
- NTDs shown in **red**, Global South diseases in **orange**, others in **grey**
- The scatter plot (Panel C) reveals the inverse relationship between research volume and isolation
