[Atlas] Score wiki quality on 20 pages (daily heuristics) done analysis:6 safety:6

Quest: Wiki Quality — Prose, Depth, and Wikipedia Parity

Layer: Atlas Priority: P90 Status: active

Problem Statement

SciDEX wiki pages currently read like auto-generated NeurWiki stubs rather than authoritative
scientific references. Key failure modes:

Bulleted-list bias — content is fragmented into bullet points and tables instead of

flowing prose that builds understanding paragraph by paragraph

Missing introductions — pages jump straight into infoboxes or section headers with no

orienting paragraph that explains what the entity is, why it matters, and how it fits into
the broader research landscape

Thin explanatory depth — facts are stated without mechanism, context, or the "so what"

that distinguishes a reference from a fact sheet

Weak cross-linking — KG relationships, related hypotheses, analyses, and wiki pages are

not woven into the prose

No quality feedback loop — improvements are one-time scripts, not a continuous process

Quality Standard

The target is gold-standard scientific wiki pages comparable to the best Wikipedia
neuroscience/molecular biology pages (e.g., wikipedia.org/wiki/Tau_protein,
wikipedia.org/wiki/Alzheimer%27s_disease) and high-quality scientific reviews. Characteristics:

• Opens with 2-4 sentences of plain-English context: what is it, why it matters in

neurodegeneration, what distinguishes it from similar entities

• Prose flows: ideas connect via transitional sentences, not just bullets
• Bullets and tables exist only for genuinely enumerable items (genetic variants, clinical

criteria, trial phases) — never as a substitute for explanation

• Each major section explains mechanism and significance, not just facts
• Internal hyperlinks to related wiki pages, KG entities, hypotheses, and analyses are

woven naturally into the prose

• Word count: disease pages ≥ 2,000 words; gene/protein pages ≥ 800 words; mechanism

pages ≥ 1,200 words (these are minima, not targets)

Quality Heuristics (LLM-Evaluable)

These heuristics replace templates. An LLM evaluator applies them to score any page on
a 0–10 scale per dimension. The goal is calibrated judgment, not checkbox compliance.

H1 — Introduction Quality (0–10)

• 0: No introduction; page starts with infobox or ## Section
• 3: One-sentence stub intro ("X is a gene involved in...")
• 5: 2–3 sentences covering identity and role but no context
• 7: Full paragraph explaining what, why it matters, and relationship to neurodegeneration
• 10: Two paragraphs; establishes significance, distinguishes from similar entities, hints

at open questions; a scientist could hand this to a non-specialist and they'd understand

H2 — Prose vs. Structure Ratio (0–10)

• 0: Page is > 80% bullet points and tables
• 3: Bullets dominate; prose exists only as section headers
• 5: Roughly equal prose and bullets; transitions are abrupt
• 7: Most sections are prose paragraphs; bullets used only for enumerable items
• 10: Flowing prose throughout; bullets/tables serve supporting roles; reads like a review article

H3 — Explanatory Depth (0–10)

• 0: Facts stated with no mechanism ("X is associated with AD")
• 3: Some mechanism mentioned but not explained
• 5: Mechanism described but without quantitative context or comparison
• 7: Mechanism explained with supporting evidence (studies cited, numbers given)
• 10: Mechanism, evidence, competing hypotheses, open questions, clinical significance all covered

H4 — Cross-Link Density (0–10)

• 0: No internal links; no connections to hypotheses, analyses, or KG
• 3: A few links to related wiki pages, but no hypothesis/analysis connections
• 5: Links to related entities and at least one hypothesis or analysis
• 7: KG relationships surfaced as prose ("...consistent with the role of [ENTITY] in [PATH]")
• 10: Rich weave of wiki links, KG context panels, linked hypotheses and analyses, and

external links to papers/tools; the page functions as a navigation hub

H5 — Wikipedia Parity (0–10)

Score by comparison: load the equivalent Wikipedia page (if it exists) and assess whether
SciDEX page is more or less comprehensive, more or less current, and better or worse for
a neurodegeneration researcher specifically.

• 0–3: Wikipedia is clearly better in depth, prose, and sourcing
• 4–6: Roughly equivalent; SciDEX may add hypothesis/KG context but lacks depth elsewhere
• 7–9: SciDEX is more comprehensive for neurodegeneration researchers; better cross-links
• 10: SciDEX is the definitive reference; Wikipedia would cite us if it could

H6 — Section Completeness (0–10)

Disease pages should cover: epidemiology, pathophysiology, genetics, clinical features,
biomarkers, therapeutics, open questions. Gene/protein pages: function, structure, expression,
disease associations, variants, therapeutic relevance. Mechanism pages: molecular detail,
circuit/systems context, evidence quality, therapeutic implications.

• Score = (sections present with substantive content) / (sections expected for entity type)

Implementation Architecture

Core Scripts

scripts/wiki_quality_scorer.py

• Samples N pages (by entity type, weighted toward high-importance pages)
• Applies all 6 heuristics via LLM (Claude claude-sonnet-4-6) with structured JSON output
• Stores scores in wiki_quality_scores table
• Generates a ranked improvement queue
• Entry point: python3 wiki_quality_scorer.py [--entity-type TYPE] [--n 20] [--budget-tokens N]

scripts/wiki_prose_improver.py

• Takes a scored page below threshold on H1 or H2
• Rewrites introduction and converts bullet-heavy sections to prose
• Uses heuristic-guided prompts (not templates)
• Compares word counts before/after; rejects regressions
• Entry point: python3 wiki_prose_improver.py [--slug SLUG] [--batch N]

scripts/wiki_crosslink_enricher.py

• For a given page, queries KG for related entities (depth 2)
• Finds linked hypotheses and analyses
• Adds inline links and a "Related Research" section if not present
• Entry point: python3 wiki_crosslink_enricher.py [--slug SLUG] [--batch N]

scripts/wiki_wikipedia_parity.py

• For a page, queries Wikipedia API for equivalent page
• Asks LLM to identify sections/depth present in WP but missing from SciDEX
• Returns a structured improvement plan
• Entry point: python3 wiki_wikipedia_parity.py [--slug SLUG] [--entity-type TYPE]

API Routes

• GET /api/wiki/quality-scores?entity_type=X&limit=50&min_score=Y&max_score=Z
• GET /api/wiki/quality-scores/<slug> — latest score for a page
• GET /senate/wiki-quality — dashboard: score distribution, improvement queue, recent changes

Feedback Loop

Score — sample 20 pages/run, score on 6 heuristics, store in wiki_quality_scores

Prioritize — sort by composite score × page_importance (disease/mechanism pages first)

Improve — prose_improver and crosslink_enricher run on lowest-scoring pages

Verify — re-score improved pages; track Δ score

Report — senate/wiki-quality shows trends over time

Recurring cadence:

• Daily: score 20 pages (rotating coverage), improve 5 lowest-scoring
• Weekly: full Wikipedia parity audit for top-50 disease/mechanism pages
• On-demand: triggered by new page creation or major content update

• Task: [46666cb6-08c6-4db8-89d3-f11f7717e8cd] Wikipedia parity audit for top 20 disease pages
• Created scripts/wiki_wikipedia_parity.py with:

- Wikipedia API integration with proper User-Agent headers
- LLM-based comparison scoring (H5 heuristic)
- Structured gap analysis (missing sections, thin coverage, structural/depth gaps)
- Orchestra task generation for top gaps

• Audit Results:

- 20 disease pages audited against Wikipedia
- 13 pages had valid Wikipedia comparisons, 4 had no equivalent (CBS, CBD, FTD, VCI, NPC, MJD, NCL)
- 2 content mismatches identified (Kabuki: theatre vs disease, Stargardt: surname vs disease)

• Top 5 Content Gaps (lowest H5 scores):

1. Parkinson's Disease: 4.2/10 - Missing clinical presentation, diagnosis, treatment sections
2. Fatal Familial Insomnia: 4.5/10 - Missing symptoms, diagnosis, treatment, case studies
3. Alzheimer's Disease: 6.5/10 - Missing signs/symptoms, diagnosis, treatment, prevention
4. Huntington's Disease: 6.5/10 - Missing clinical triad, diagnosis, treatment, epidemiology
5. Multiple System Atrophy: 6.5/10 - Missing diagnosis, management, historical context

• Generated Tasks: 5 Orchestra task definitions saved to scripts/wikipedia_parity_tasks.json

- Tasks need to be created from main directory: orchestra task create --project SciDEX ...

• Files Modified: scripts/wiki_wikipedia_parity.py (new), scripts/wikipedia_parity_tasks.json (new), logs/wikipedia_parity_audit_20260410_042536.json (results)
• Next Steps: Create Orchestra tasks from main directory, then execute tasks sequentially

Attribution

The current audit state was produced by:

• 7397845fd — [Atlas] Add Wikipedia parity audit script; run audit on top 20 disease pages; create 5 improvement tasks [task:46666cb6...]

- This commit exists on an orphan branch, NOT on main
- The audit script was never merged to main (deprecated/removed during SQLite retirement)

• 1577f9737 — [Atlas] Add Wikipedia parity audit script and run top-20 disease audit [task:46666cb6...]

Notes

Original audit findings (2026-04-10):
The original audit identified these 5 biggest gaps vs Wikipedia:

Parkinson's Disease: H5=4.2 — missing clinical presentation, diagnosis, treatment

Fatal Familial Insomnia: H5=4.5 — missing symptoms, diagnosis, treatment, case studies

Alzheimer's Disease: H5=6.5 — missing signs/symptoms, diagnosis, treatment, prevention

Huntington's Disease: H5=6.5 — missing clinical triad, diagnosis, treatment, epidemiology

Multiple System Atrophy: H5=6.5 — missing diagnosis, management, historical context

Verification (2026-04-20): Current state shows substantial improvement on all 5 pages:

Page	Words	Missing sections vs Wikipedia (original)	Current state
diseases-parkinsons-disease	8,807	prognosis, history	All 9 key sections present
diseases-fatal-familial-insomnia	4,032	etiology	All 9 key sections present
diseases-alzheimers-disease	5,365	epidemiology	8/9 present (epidemiology MISSING)
diseases-huntingtons	4,606	etiology, pathophysiology, prognosis	6/9 present (etiology MISSING, pathophysiology MISSING, prognosis MISSING)
diseases-multiple-system-atrophy	5,399	(original gaps unclear)	All 9 key sections present

Key observation: The pages have been substantially improved since the original audit (likely by the prose_improver tasks that ran on 2026-04-10). The orphan-branch audit script was NEVER merged to main — it was deprecated when the SQLite scidex.db was retired in favor of PostgreSQL.

H5 scoring status: The wiki_quality_scores table has 96 rows with H5 scores. Parkinson's disease has TWO entries (H5=2.0 on 2026-04-10 13:46 and H5=6.0 on 2026-04-10 22:39), showing active improvement over the same day. The newer H5=6.0 score reflects the improved content.

Recommendation: The improvement tasks from the original audit were never created via Orchestra (the wikipedia_parity_tasks.json file was generated but tasks were not actually created due to the orphan branch issue). A follow-up task should create those 5 improvement tasks if they haven't been addressed by subsequent prose_improver runs.
