Organizations Enriched

# Organization Wikidata ID Type Verification
23 Stichting Exploitatie Industrieel Smalspoormuseum Q1911968 museum ✓ narrow gauge railway museum in Drenthe
24 Stichting Zeemuseum Miramar Q22006174 museum ✓ maritime museum in Vledder
26 Stichting Cultuurhistorisch Streek- en Handkarren Museum De Wemme Q56461228 museum ✓ handcart museum in Zuidwolde

No Matches Found

# Organization Type Reason
18 Stichting Harmonium Museum Nederland museum Museum closed/collection relocated to Museum Geelvinck
19 Historische Vereniging Carspel Oderen historische vereniging Small local historical society, not in Wikidata
20 Historische Vereniging De Wijk Koekange historische vereniging Small local historical society, not in Wikidata
21 Historische Kring Hoogeveen historische vereniging Local historical society, not in Wikidata
22 Historische Vereniging Nijeveen historische vereniging Small local historical society, not in Wikidata
25 Museum de Proefkolonie museum UNESCO site (Q64685403) found but not specific museum

Key Insight: Historical societies (historische vereniging/kring) have very low Wikidata coverage (0/4 = 0%). Specialty niche museums perform better (3/5 = 60%).


Batch 2 Details

Date: 2025-11-17
Records: 11-17 (7 municipal archives in Drenthe)
Method: SPARQL queries for Dutch municipalities (P31: Q2039348)

Search Strategy Effectiveness

Method 1: Direct Search (wikidata-authenticated_search_entity)

  • Success rate: 60% (9/15 records)
  • Best for: Well-known museums, national institutions
  • Limitations: Often returns wrong entity type (city vs. municipality)

Method 2: SPARQL Queries (wikidata-authenticated_execute_sparql)

  • Success rate: 100% (6/6 municipalities)
  • Best for: Municipalities, government institutions
  • Query pattern:
SELECT ?item ?itemLabel WHERE {
  ?item wdt:P31 wd:Q2039348 .  # Instance of: Dutch municipality
  ?item rdfs:label ?label .
  FILTER(CONTAINS(LCASE(?label), "municipality_name"))
  SERVICE wikibase:label { bd:serviceParam wikibase:language "nl,en". }
}
  1. Museums: Direct search first, SPARQL fallback - expect 60-70% success
  2. Municipal archives: Always use SPARQL (100% success)
  3. Regional archives: Direct search or ISIL code lookup
  4. Historical societies: Very low Wikidata coverage (0% so far) - mark as no_match_found
  5. Libraries: Direct search, expect 70-80% success

No-Match Cases

Organization Type Reason
Stichting Drents Museum De Buitenplaats museum Branch location (not in Wikidata)
Samenwerkingsorganisatie De Wolden/Hoogeveen archief Inter-municipal partnership (not in Wikidata)
Stichting Harmonium Museum Nederland museum Museum closed/collection relocated
Historische Vereniging Carspel Oderen historische vereniging Small local society, not in Wikidata
Historische Vereniging De Wijk Koekange historische vereniging Small local society, not in Wikidata
Historische Kring Hoogeveen historische vereniging Local historical society, not in Wikidata
Historische Vereniging Nijeveen historische vereniging Small local society, not in Wikidata
Museum de Proefkolonie museum Couldn't find specific museum (UNESCO site found instead)

Patterns:

  • Branch locations and collaborative organizations less likely to have Wikidata entries
  • Historical societies (vereniging/kring) have essentially no Wikidata coverage
  • Closed/relocated museums may not have current Wikidata entries

Next Steps

Immediate (Next Batch)

  • Records 27-50: Continue with remaining Drenthe institutions and move to other provinces
  • Estimated time: 45-60 minutes
  • Expected success: 50-70% (mix of museum types and organization types)

Short Term (Next 100 Records)

  • Records 27-100: Complete Drenthe province, start Friesland/Groningen
  • Estimated time: 3-4 hours
  • Expected enriched: 50-60 records

Medium Term (Next 500 Records)

  • Records 27-500: Multiple provinces, diverse organization types
  • Estimated time: 12-15 hours
  • Expected enriched: 300-350 records

Long Term (Full Dataset)

  • All 1,351 records: Complete enrichment
  • Estimated time: 18-22 hours total (adjusted for lower success rate)
  • Expected enriched: 850-1,000 records (65-75% success rate)

Technical Notes

Batch Processing Script

Created update scripts for systematic processing:

  • /scripts/update_nde_batch_2.py - Municipal archives (100% success)
  • /scripts/update_nde_batch_3.py - Specialty museums and historical societies (33% success)
  • Loads YAML file
  • Creates backup before modifications
  • Updates records with Q-numbers
  • Marks no-match cases with wikidata_enrichment_status: no_match_found
  • Saves enriched data
  • Reports statistics

Wikidata API Performance

  • Search queries: ~1-2 seconds per request
  • SPARQL queries: ~2-3 seconds per request
  • Verification checks: ~0.5 seconds per request
  • Rate limiting: 30-second pause between batches recommended

Data Quality

  • All Q-numbers verified with wikidata-authenticated_get_metadata
  • No duplicates detected (each Q-number used once)
  • No errors in batch processing

Files Updated

Data Files

  • /data/nde/voorbeeld_lijst_organisaties_en_diensten-totaallijst_nederland.yaml (updated with 3 new Q-numbers + 6 no-match markers)

  • Previous backups: 20251117_121119 (Batch 2), earlier backups from test phase

Scripts

  • /scripts/update_nde_batch_2.py (municipal archives - 100% success)
  • /scripts/update_nde_batch_3.py (specialty museums/societies - 33% success)

Recommendations

For Efficient Completion

  1. Batch by organization type: Process all municipalities together, then museums, then libraries, etc.
  2. Use SPARQL for government institutions: 100% success rate
  3. Direct search for cultural institutions: Good success rate for well-known organizations
  4. Manual review queue: Flag low-confidence matches for human verification
  5. Checkpoint system: Save after every 50 records to enable recovery

For Quality Assurance

  • Verify all Q-numbers before final commit
  • Check for duplicate Q-numbers across dataset
  • Cross-reference with ISIL codes where available
  • Manual review for organizations with multiple potential matches

Next Session Checklist

  • Process records 18-26 (specialty museums and historical societies) - COMPLETE
  • Process records 27-50 (continue Drenthe, start other provinces)
  • Process records 51-100 (expand to Friesland/Groningen)
  • Create validation script for Q-number verification
  • Generate statistics dashboard
  • Consider automation for remaining municipal archives

Progress: 1.4% complete (19/1,351)
Estimated completion: 18-22 hours remaining (adjusted)
Success rate: 70% (below 80% target due to historical societies)
Status: ⚠️ Adjusted expectations - historical societies have 0% match rate
