Proven Search Strategies

Strategy 1: SPARQL for Municipalities (100% success)

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". }
}

When to use: All records with type_organisatie: archief and org name contains "Gemeente"

Strategy 2: Direct Search (75-80% success)

q_number = wikidata_authenticated_search_entity("Museum Name City Netherlands")

When to use: Museums, libraries, cultural institutions

Strategy 3: Verification (Required for all)

metadata = wikidata_authenticated_get_metadata(q_number, language="nl")
# Verify Label and Description match expected organization

Always verify: Every Q-number before adding to dataset


Next Records to Process (18-30)

18. Stichting Harmonium Museum Nederland (museum)
19. Historische Vereniging Carspel Oderen (historische vereniging)
20. Historische Vereniging De Wijk Koekange (historische vereniging)
21. Historische Kring Hoogeveen (historische vereniging)
22. Historische Vereniging Nijeveen (historische vereniging)
23. [Historische vereniging]
24. [Museum/Archive]
... (continuing through Drenthe institutions)

Expected success rate: 60-70% (historical societies have lower Wikidata coverage)

How to Continue Enrichment

Process 10-20 records at a time:

  1. Read next batch of records:
python3 -c "
import yaml
with open('data/nde/voorbeeld_lijst_organisaties_en_diensten-totaallijst_nederland.yaml', 'r') as f:
    orgs = yaml.safe_load(f)
for i in range(17, 30):  # Next 13 records
    print(f\"{i+1}. {orgs[i]['organisatie']} ({orgs[i].get('type_organisatie', 'N/A')})\")
"
  1. Search Wikidata for each organization (use appropriate strategy)

  2. Create batch update script (copy update_nde_batch_2.py, modify mapping)

  3. Run update script and verify results

  4. Repeat for next batch

Advantages:

  • High quality control
  • Can handle ambiguous matches
  • Learn patterns for automation

Estimated time: 30-45 minutes per batch of 10-20 records

Option 2: Semi-Automated Processing

Use Python script with Wikidata MCP tools:

# Pseudo-code for automation
for org in organizations[17:]:
    if org.get('wikidata_id'):
        continue  # Skip already enriched
    
    # Search strategy based on type
    if 'Gemeente' in org['organisatie']:
        q_number = sparql_municipality_search(org['plaatsnaam_bezoekadres'])
    else:
        q_number = wikidata_search(org['organisatie'], org.get('type_organisatie'))
    
    # Verify and update
    if q_number and verify_match(q_number, org):
        org['wikidata_id'] = q_number
        save_checkpoint()

Advantages:

  • Faster processing
  • Consistent methodology
  • Can run overnight

Challenges:

  • Requires error handling
  • May need manual review queue
  • API rate limits

Estimated Time to Completion

Conservative Estimate (Manual Batches)

  • Records per hour: 30-40
  • Total remaining: 1,336 records
  • Estimated hours: 33-45 hours
  • With 2-hour sessions: 17-23 sessions

Optimistic Estimate (Semi-Automated)

  • Records per hour: 100-150
  • Total remaining: 1,336 records
  • Estimated hours: 9-14 hours
  • With 3-hour sessions: 3-5 sessions

Realistic Estimate (Mixed Approach)

  • Municipalities (automated): ~200 records @ 150/hour = 1.5 hours
  • Museums (manual): ~500 records @ 40/hour = 12.5 hours
  • Historical societies (manual): ~300 records @ 30/hour = 10 hours
  • Libraries/Other (mixed): ~336 records @ 50/hour = 7 hours
  • Total: ~31 hours (10-15 sessions)

Key Insights from Batches 1-2

What Works Exceptionally Well

  1. SPARQL for municipalities: 100% success rate, always use this
  2. Verification step: Prevents false positives, always verify
  3. Batch processing: Efficient, creates clear checkpoints
  4. Backup before updates: Safe, allows rollback if needed

⚠️ Challenges Encountered

  1. Direct search ambiguity: Sometimes returns city instead of municipality
  2. Historical societies: Lower Wikidata coverage (expect 50-70%)
  3. Branch locations: Usually not in Wikidata (link to parent institution)
  4. Collaborative organizations: Inter-municipal partnerships often missing

💡 Lessons for Full Dataset

  1. Batch by type: Process all municipalities together (efficiency)
  2. Set expectations: Not all organizations will have Q-numbers
  3. Manual review queue: Flag ambiguous matches for verification
  4. ISIL code leverage: Use P791 property for precise matching
  5. Progress tracking: Save checkpoints every 50 records

Immediate Next Steps

For Next Session

  1. Process records 18-30 (historical societies and remaining Drenthe)
  2. Create Batch 3 update script (copy and modify Batch 2 script)
  3. Update progress report with Batch 3 statistics
  4. Consider semi-automation for municipalities in other provinces

For Future Sessions

  1. Process next 100 records (expand beyond Drenthe)
  2. Create validation script (check for duplicates, verify Q-numbers)
  3. Generate statistics dashboard (enrichment by province, type, etc.)
  4. Plan automation for remaining ~1,200 records
