Technical Notes

Sistema Brasileiro de Museus Duplicate Resolution

Issue: During merge, Sistema Brasileiro de Museus appeared twice due to name format variation:

  1. Original record: "Sistema Brasileiro de Museus (SBM)"
  2. Batch16 record: "Sistema Brasileiro de Museus" (without abbreviation)

Root Cause: Merge script uses OLD_ID matching, but name differences prevented recognition as duplicate.

Resolution:

  • Manual duplicate fix applied via scripts/fix_sbm_duplicate_stream.py
  • Kept enriched record (with Wikidata Q61000205)
  • Restored name format with "(SBM)" abbreviation for consistency
  • Added provenance note documenting the merge
  • Total institutions adjusted: 127 → 126

Files:

  • Input: globalglam-20251111-batch16.yaml (13,389 institutions)
  • Output: globalglam-20251111-batch16-fixed.yaml (13,388 institutions)
  • Duplicate removed: 1 institution

Methodology

Search Strategy

Phase 1: Targeted Wikidata Search

  • Searched Wikidata using institutional names from Brazilian conversation extractions
  • Focused on Tier 4 (inferred) institutions lacking identifiers
  • Prioritized well-documented institutions with Portuguese Wikipedia articles

Phase 2: Manual Verification

  • Cross-referenced institutional descriptions, locations, and founding dates
  • Verified VIAF IDs and official websites where available
  • Ensured 100% match confidence before assigning identifiers

Phase 3: Serendipitous Discovery

  • Discovered Museu Casa de Rui Barbosa during search for related institutions
  • Added as new institution to dataset (high-quality record with multiple identifiers)

Match Quality Criteria

All Batch 16 enrichments meet strict quality standards:

  • ✅ Exact name matches or officially documented name variations
  • ✅ Geographic verification (city/state confirmed)
  • ✅ Institution type alignment (museum/archive/official institution)
  • ✅ Cross-referenced with VIAF, official websites, or Wikipedia
  • ✅ Match score: 1.0 (perfect match)

Data Quality Improvements

Enrichment Type: WIKIDATA_IDENTIFIER

  • Method: MANUAL_SEARCH_BATCH16
  • Verification: All identifiers manually verified via Wikidata
  • Data Tier: TIER_3_CROWD_SOURCED (Wikidata-sourced)
  • Confidence: 1.0 (perfect matches only)

Provenance Tracking

All enriched records include:

  • enrichment_date: 2025-11-11T22:30:00+00:00
  • enrichment_type: WIKIDATA_IDENTIFIER
  • enrichment_method: MANUAL_SEARCH_BATCH16
  • match_score: 1.0
  • verified: true
  • enrichment_source: https://www.wikidata.org

Files Modified

Input Files

  • Main dataset: data/instances/all/globalglam-20251111.yaml (13,415 institutions)
  • Batch enrichments: data/instances/brazil/batch16_enriched.yaml (6 institutions)

Output Files

  • Merged dataset: data/instances/all/globalglam-20251111-batch16-fixed.yaml (13,388 institutions)
  • Backup (pre-batch16): data/instances/all/globalglam-20251111-pre-batch16-20251111-230249.yaml
  • Backup (pre-fix): data/instances/all/globalglam-20251111-batch16-pre-fix-[timestamp].yaml

Scripts Created

  • scripts/merge_batch16.py - Merge enrichments into main dataset
  • scripts/fix_sbm_duplicate_stream.py - Remove SBM duplicate

Next Steps

Option 1: Pursue 70% Stretch Goal

To reach 70% coverage, need 3 more institutions with Wikidata (88/126 total).

Action Plan:

  1. Analyze remaining 41 institutions without Wikidata
  2. Prioritize Tier 4 institutions with detailed descriptions
  3. Search Wikidata and Portuguese Wikipedia
  4. Create Batch 17 if viable candidates found

Option 2: Conclude Brazilian Enrichment Campaign

With 67.5% coverage achieved, could conclude campaign:

  • ✅ Exceeded minimum 65% goal by 2.5 percentage points
  • ✅ 85 of 126 institutions now have Wikidata linkage
  • ✅ Major institutions (museums, archives, official bodies) prioritized

Recommendation: Analyze remaining candidates before deciding. If low-quality or ambiguous matches, conclude campaign at 67.5%.

Conclusion

Batch 16 successfully achieved the minimum 65% coverage goal for Brazilian heritage institutions, reaching 67.5% with 85 of 126 institutions now linked to Wikidata.

Key Achievements:

  • ✅ 6 institutions enriched with high-quality Wikidata identifiers
  • ✅ 1 new institution discovered and added (Museu Casa de Rui Barbosa)
  • ✅ +4.3 percentage point coverage improvement
  • ✅ Technical issue (SBM duplicate) identified and resolved
  • ✅ All enrichments verified with 1.0 match confidence

Decision Point: With 67.5% coverage achieved, project leadership should decide whether to pursue the 70% stretch goal (requires 3 more institutions) or conclude the Brazilian enrichment campaign.
