Fix Japan Dataset - Remove Synthetic Q-Numbers
|
|
|
|
CRITICAL DATA INTEGRITY FIX:
|
|
The Japan dataset (jp_institutions_resolved.yaml) contains 3,426 synthetic Q-numbers
|
|
that DO NOT exist in Wikidata. This violates the project's data integrity policy.
|
|
|
|
Per AGENTS.md:
|
|
🚨 CRITICAL POLICY: REAL IDENTIFIERS ONLY 🚨
|
|
SYNTHETIC Q-NUMBERS ARE STRICTLY PROHIBITED IN THIS PROJECT.
|
|
|
|
This script:
|
|
1. Strips all synthetic Q-numbers from GHCIDs
|
|
2. Restores base GHCIDs (without Q-suffix)
|
|
3. Updates GHCID history to document the fix
|
|
4. Marks institutions with needs_wikidata_enrichment flag
|
|
5. Preserves all other data
|
|
|
|
Example transformation:
|
|
BEFORE: ghcid: JP-HO-SAP-L-SSL-Q61382582 (FAKE Q-number)
|
|
AFTER: ghcid: JP-HO-SAP-L-SSL (base GHCID)
|
|
needs_wikidata_enrichment: true

## Critical Data Integrity Fix
|
|
|
|
### Problem Identified
|
|
|
|
The Japan dataset (`jp_institutions_resolved.yaml`) contained **{fixed_count:,} synthetic Q-numbers** that do not exist in Wikidata.
|
|
|
|
**Example violations**:
|
|
```yaml
|
|
# BEFORE (INVALID)
|
|
ghcid: JP-HO-SAP-L-SSL-Q61382582
|
|
reason: "Q-number Q61382582 added to resolve collision. Source: Synthetic (from ISIL code hash)"
|
|
|
|
# Q61382582 does NOT exist in Wikidata!
|
|
# https://www.wikidata.org/wiki/Q61382582 → 404 NOT FOUND
|
|
```
|
|
|
|
### Policy Violation
|
|
|
|
Per `AGENTS.md` data integrity policy:
|
|
|
|
> **🚨 CRITICAL POLICY: REAL IDENTIFIERS ONLY 🚨**
|
|
>
|
|
> **SYNTHETIC Q-NUMBERS ARE STRICTLY PROHIBITED IN THIS PROJECT.**
|
|
>
|
|
> All Wikidata Q-numbers used in GHCIDs MUST be:
|
|
> - ✅ Real Wikidata entity identifiers (verified via API query)
|
|
> - ✅ Confirmed to match the institution (fuzzy match score > 0.85)
|
|
> - ✅ Resolvable at `https://www.wikidata.org/wiki/Q[number]`
|
|
>
|
|
> ❌ **NEVER** generate synthetic/fake Q-numbers from hashes, numeric IDs, or algorithms
|
|
|
|
### Root Cause
|
|
|
|
The original processing script generated Q-numbers algorithmically from ISIL code hashes to resolve GHCID collisions, without verifying they existed in Wikidata.
|
|
|
|
### Fix Applied
|
|
|
|
**Transformation**:
|
|
1. Stripped all synthetic Q-numbers from GHCIDs
|
|
2. Restored base GHCIDs (without Q-suffix)
|
|
3. Added `needs_wikidata_enrichment: true` flag to {fixed_count:,} institutions
|
|
4. Updated GHCID history to document the cleanup
|
|
5. Added provenance notes explaining the fix
|
|
|
|
**Example**:
|
|
```yaml
|
|
# AFTER (VALID)
|
|
ghcid: JP-HO-SAP-L-SSL # Base GHCID without Q-number
|
|
needs_wikidata_enrichment: true
|
|
ghcid_history:
|
|
- ghcid: JP-HO-SAP-L-SSL
|
|
valid_from: "2025-11-20T..."
|
|
reason: >-
|
|
Synthetic Q-number removed (was JP-HO-SAP-L-SSL-Q61382582).
|
|
Restored base GHCID. Per AGENTS.md data integrity policy,
|
|
synthetic Q-numbers are prohibited. Institution flagged for
|
|
real Wikidata enrichment.
|
|
```
|
|
|
|
## Statistics
|
|
|
|
| Metric | Count |
|
|
|--------|-------|
|
|
| **Total institutions** | {len(cleaned_institutions):,} |
|
|
| **Fixed (synthetic Q-numbers removed)** | {fixed_count:,} ({fixed_count/len(cleaned_institutions)*100:.1f}%) |
|
|
| **Unchanged (no synthetic Q-numbers)** | {unchanged_count:,} ({unchanged_count/len(cleaned_institutions)*100:.1f}%) |
|
|
| **Institutions needing Wikidata enrichment** | {fixed_count:,} |
|
|
|
|
## Next Steps
|
|
|
|
### Immediate Actions
|
|
|
|
1. ✅ **Cleaned dataset saved**: `jp_institutions_cleaned.yaml`
|
|
2. ⏳ **Replace original dataset** with cleaned version
|
|
3. ⏳ **Update unified database** to use cleaned Japan data
|
|
|
|
### Follow-up: Real Wikidata Enrichment
|
|
|
|
The {fixed_count:,} institutions flagged with `needs_wikidata_enrichment: true` should undergo **real Wikidata lookup**:
|
|
|
|
**Workflow**:
|
|
1. Query Wikidata SPARQL endpoint for Japanese heritage institutions
|
|
2. Fuzzy match institution names (threshold > 0.85)
|
|
3. Verify matches by comparing location (city, prefecture)
|
|
4. Add REAL Q-numbers to identifiers
|
|
5. Update GHCIDs with verified Q-numbers
|
|
6. Document enrichment in provenance metadata
|
|
|
|
**Reference**: See `docs/WIKIDATA_ENRICHMENT.md` for detailed procedures
|
|
|
|
## File Locations
|
|
|
|
- **Original (with synthetic Q-numbers)**: `{INPUT_FILE}`
|
|
- **Cleaned (synthetic Q-numbers removed)**: `{OUTPUT_FILE}`
|
|
- **Cleanup report**: `{REPORT_FILE}`
|
|
|
|
## Data Integrity Guarantee
|
|
|
|
✅ All Q-numbers in the cleaned dataset are now either:
|
|
- Real Wikidata identifiers (verified), OR
|
|
- Absent (base GHCID only, awaiting real Wikidata enrichment)
|
|
|
|
❌ Zero synthetic/fake Q-numbers remain in the dataset
