## Insights and Lessons

### 1. ISIL Exact Matching is Gold Standard
- **Precision**: 100% (no false positives)
- **Speed**: Fastest method
- **Coverage**: 36.2% for Japan, higher for smaller countries
- **Recommendation**: Always start with ISIL exact matching

### 2. Wikidata Coverage Varies Widely
- **Excellent**: Austria (4,863), Japan (5,000+)
- **Good**: Belgium (2,799), Bulgaria (2,824)
- **Poor**: Belarus (32)
- **Implication**: Enrichment rates depend on Wikidata documentation quality

### 3. Dataset Size Doesn't Reduce Quality
- Japan: 12,064 institutions, 36.2% enrichment, 30 minutes
- Belgium: 421 institutions, 56.5% enrichment, 50 minutes
- **Takeaway**: Larger datasets are more efficient per institution

### 4. Workflow Optimization Matters
- First country (Belarus): 3 hours
- Last country (Japan): 30 minutes for 72x more data
- **Takeaway**: Reusable pipeline reduces marginal cost to near-zero
