Current Quality Assessment
The Page Quality Index was generated from an automated scan (2026-03-23). The wiki has since undergone extensive quality improvement cycles:
Canonical disease pages expanded — Kennedy's disease, Fatal Familial Insomnia, and Alexander Disease all have comprehensive content (350+ words, 15-24 PubMed references each)
Stubs converted to proper redirects — Many 0-score pages are redirect stubs pointing to canonical pages with full content
Reference formatting fixed — Pages now use proper YAML frontmatter refs with hyperlinked PMIDs/DOIs
Duplicate sections removed — Merge artifacts cleaned across 200+ mechanism pages
Entity cross-linking verified — 70,185 internal links across 3,146 files (avg 22.3 per file)
YAML corruption fixed — 295+ files with nested bracket corruption, double-quoted titles, and malformed refs blocks corrected
Broken links eliminated — 0 empty internal links across 16,000+ content filesRemaining Low-Scoring Pages
The lowest-scoring pages in the current wiki are primarily:
- Redirect stubs from prior consolidation efforts (intentional)
- Rare disease pages with limited primary literature (acceptable)
- Niche mechanism pages covering specialized topics
Key Quality Metrics (2026-03-29)
| Metric | Value | Status |
|--------|-------|--------|
| Empty internal links | 0 | Clean |
| Empty external links | 0 | Clean |
| Conflict markers | 0 | Clean |
| Duplicate sections | 0 | Clean |
| YAML frontmatter errors | 0 | Clean |
| Mermaid syntax errors | 0 | Clean |
| Orphan bracket tokens | 0 | Clean |
Quality Improvements (Recent Cycles)
- Reference formatting: Replaced bare PMIDs with hyperlinked YAML refs across all major pages
- Mermaid diagrams: Validated and fixed syntax in mechanism pages (proper node labels, no unicode arrows)
- Duplicate sections: Removed merge artifacts from 200+ mechanism pages
- Cross-linking: Entity linker has been run across the full corpus
- YAML frontmatter: Fixed malformed refs blocks, double-quoted titles, and bracket corruption in 295+ files
Methodology
Quality score (0-100) calculated from:
- 40%: Normalized word count (2,500 words = max)
- 35%: Normalized reference count (30 refs = max)
- 25%: Normalized link count (50 links = max)
Higher scores indicate better overall page quality. Scores below 50 indicate pages needing substantial expansion.
