Japan Wikidata Enrichment - Real Q-Numbers Only
This script performs REAL Wikidata enrichment for 3,426 Japanese heritage institutions
that were flagged with needs_wikidata_enrichment: true after synthetic Q-number cleanup.
Per AGENTS.md data integrity policy:
🚨 CRITICAL POLICY: REAL IDENTIFIERS ONLY 🚨
All Q-numbers 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]
Workflow:
1. Load Japan dataset, filter institutions with needs_wikidata_enrichment: true
2. Query Wikidata SPARQL for Japanese heritage institutions by type
3. Fuzzy match institution names (threshold > 0.85)
4. Verify matches by location (city, prefecture)
5. Add REAL Q-numbers to identifiers array
6. Update GHCIDs with verified Q-numbers (if collision resolution requires)
7. Update GHCID history and provenance metadata
8. Save enriched dataset and generate report
Usage:
python scripts/enrich_japan_wikidata_real.py
Options:
--dry-run Show matches without modifying dataset
--limit N Process only first N institutions (for testing)
--batch-size N SPARQL query batch size (default: 50)

## Executive Summary
This report documents the Wikidata enrichment process for Japanese heritage institutions
that were flagged with `needs_wikidata_enrichment: true` after synthetic Q-number cleanup.
### Statistics
| Metric | Count | Percentage |
|--------|-------|------------|
| **Total institutions needing enrichment** | {self.stats['needs_enrichment']:,} | 100.0% |
| **Matches found** | {self.stats['matches_found']:,} | {match_rate:.1f}% |
| **High confidence (≥90%)** | {self.stats['high_confidence']:,} | {self.stats['high_confidence']/self.stats['needs_enrichment']*100:.1f}% |
| **Medium confidence (85-89%)** | {self.stats['medium_confidence']:,} | {self.stats['medium_confidence']/self.stats['needs_enrichment']*100:.1f}% |
| **No match found** | {self.stats['no_match']:,} | {self.stats['no_match']/self.stats['needs_enrichment']*100:.1f}% |
| **API errors** | {self.stats['api_errors']:,} | - |
### Match Quality
- **✅ High Confidence**: {self.stats['high_confidence']:,} institutions matched with ≥90% similarity
- **✅ Medium Confidence**: {self.stats['medium_confidence']:,} institutions matched with 85-89% similarity
- **⚠️ No Match**: {self.stats['no_match']:,} institutions require manual review
### Data Integrity
✅ **All Q-numbers verified**: Every Q-number was verified to exist in Wikidata via API
✅ **Fuzzy matching**: All matches meet ≥85% name similarity threshold
✅ **Location verification**: Matches checked against city/prefecture data
✅ **REAL identifiers only**: Zero synthetic Q-numbers generated
## Enrichment Method
### 1. SPARQL Query
Queried Wikidata for Japanese heritage institutions by type:
- Libraries (Q7075)
- Museums (Q33506)
- Archives (Q166118)
- Galleries (Q1007870)
- Research Centers (Q31855)
### 2. Fuzzy Name Matching
Used `rapidfuzz` library with multiple algorithms:
- `fuzz.ratio()` - Direct string comparison
- `fuzz.partial_ratio()` - Substring matching
- `fuzz.token_sort_ratio()` - Word order independence
**Threshold**: ≥85% similarity required
### 3. Location Verification
Verified matches by:
- City name in Wikidata label
- Coordinate proximity (within ~10km)
**Bonus**: +10 points for location match
### 4. Q-Number Verification
Every Q-number verified via Wikidata API:
```python
# Safety check before adding to dataset
if not self.verify_qnumber_exists(match.q_number):
print(f"⚠️ Q-number {{match.q_number}} does NOT exist! Skipping.")
return institution
```
## Next Steps
### Institutions Without Matches ({self.stats['no_match']:,})
These institutions require manual review:
1. Search Wikidata manually by name and location
2. Check for transliteration variants (romaji vs. kanji)
3. Verify institution still exists (may be closed)
4. Consider creating new Wikidata entity if confirmed missing
### GHCID Collision Resolution
Currently, Q-numbers are added to `identifiers` array but NOT to GHCIDs.
To add Q-numbers to GHCIDs (collision resolution):
1. Load full dataset and detect base GHCID collisions
2. For colliding institutions, append Q-number to GHCID
3. Update ghcid_history with collision documentation
