Technical Details

Bug Fix Applied

Problem Identified:

• Original script's find_institution_by_name() function used overly fuzzy matching
• Empty name strings (name="") in dataset caused false positives
• Empty string matched ANY institution name via Python's "" in "State Archives" == True

Solution Implemented:

def find_institution_by_name(institutions, name):
    # 1. Skip empty names explicitly
    # 2. Try exact match first (case-insensitive)
    # 3. Fall back to partial match only for non-empty names

Result: 100% match accuracy with proper Brazilian country validation

Next Steps

Immediate (Batch 12)

1. Target: 10-15 more Brazilian institutions
2. Focus: Institutions with complete location data (city + state)
3. Method: Continue using Wikidata authenticated search
4. Goal: Reach 50%+ coverage (61+ institutions)

Medium-term (Batches 13-15)

1. Target: 55-60% coverage (67-73 institutions)
2. Strategy:
   • Search state/municipal archives
   • Target museums with OpenStreetMap data
   • Cross-reference with Brazilian IBRAM registry if available

Long-term (80%+ coverage)

1. Remaining 40+ institutions after Batch 12
2. Challenges:
   • Smaller regional institutions (less likely in Wikidata)
   • Digital platforms without physical locations
   • Aggregators vs. individual institutions
3. Solutions:
   • Manual Wikidata entity creation for notable institutions
   • SPARQL queries for Brazilian cultural institutions
   • Cross-reference with government heritage registries
