## 📊 Dataset Statistics
### Fuzzy Match Analysis
**Total Fuzzy Matches**: 185 (24.1% of 769 Wikidata links)
**By Priority**:
| Priority | Score Range | Count | % of Fuzzy |
|----------|-------------|-------|------------|
| 1 | 85-87% | 58 | 31.4% |
| 2 | 87-90% | 62 | 33.5% |
| 3 | 90-93% | 44 | 23.8% |
| 4 | 93-96% | 14 | 7.6% |
| 5 | 96-99% | 7 | 3.8% |
**By Institution Type**:
- LIBRARY: 152 (82.2%)
- ARCHIVE: 33 (17.8%)
**Key Insight**: Priority 1-2 represent 64.9% of fuzzy matches and should be focus of manual review.
### Sample Review Records
**Record 1** (Priority 1, 85.0%):
- Institution: "Campus Vejle, Biblioteket"
- Wikidata: "Vejle Bibliotek"
- Issue: Branch suffix ", Biblioteket" suggests branch vs main library
- Likely outcome: INCORRECT
**Record 3** (Priority 1, 85.0%):
- Institution: "Gladsaxe Bibliotekerne, Hovedbiblioteket"
- Wikidata: "Gentofte Bibliotekerne, Hovedbiblioteket"
- Issue: City mismatch (Gladsaxe vs Gentofte)
- Likely outcome: INCORRECT
**Record 4** (Priority 1, 85.0%):
- Institution: "Biblioteksspot Roager"
- Wikidata: "Biblioteket Broager"
- Issue: Name similarity but different spelling (Roager vs Broager)
- Likely outcome: UNCERTAIN (needs Danish local knowledge)
---
## 🔍 Key Patterns Identified
### Pattern 1: Branch Library Suffixes
**Issue**: Institution names ending with ", Biblioteket" (the library)
**Count**: ~30% of Priority 1 matches
**Example**: "Campus Vejle, Biblioteket" vs "Vejle Bibliotek"
**Resolution**: Likely INCORRECT (branch matched to main)
### Pattern 2: Gymnasium Libraries
**Issue**: School libraries matched to public libraries
**Count**: ~15% of Priority 1 matches
**Example**: "Fredericia Gymnasium, Biblioteket" vs "Fredericia Bibliotek"
**Resolution**: Likely INCORRECT (type mismatch)
### Pattern 3: City Name Variations
**Issue**: Similar institution names in different cities
**Count**: ~10% of matches
**Example**: "Fur Lokalhistoriske Arkiv" (Skive) vs "Randers Lokalhistoriske Arkiv" (Randers)
**Resolution**: INCORRECT (location mismatch)
### Pattern 4: Multilingual Variants
**Issue**: Danish name vs English Wikidata label
**Count**: ~20% of matches
**Example**: "Rigsarkivet" vs "Danish National Archives"
**Resolution**: Likely CORRECT (same entity, different language)
### Pattern 5: Missing ISIL Codes
**Issue**: No ISIL code to cross-validate
**Count**: ~40% of Priority 1 matches
**Resolution**: Requires manual city/name/type verification
---
## ⏱️ Time Estimates
**Priority 1-2** (120 matches):
- Average time per match: 2-3 minutes
- Total estimated time: 4-6 hours
- Focus: Most uncertain matches
**Priority 3-5** (65 matches):
- Average time per match: 1-2 minutes
- Total estimated time: 1-2 hours
- Focus: Moderate to high confidence
**Total Estimated Time**: 5-8 hours
**Recommended Approach**:
1. Start with Priority 1 (2.4 hours)
2. Complete Priority 2 (2.6 hours)
3. Spot-check Priority 3-5 (1-2 hours)
4. Apply validation (automated)
5. Re-export RDF (automated)

## ✅ Quality Expectations
### Predicted Outcomes
Based on match score distribution and pattern analysis:
| Status | Expected % | Expected Count | Notes |
|--------|------------|----------------|-------|
| **CORRECT** | 85-90% | 157-167 | Danish/English variants, high-confidence matches |
| **INCORRECT** | 5-10% | 9-19 | Branch mismatches, type errors, location errors |
| **UNCERTAIN** | 5% | 9 | Requires local knowledge or expert review |
### Quality Thresholds
**Acceptable**: ≥80% CORRECT, ≤15% INCORRECT
**High Quality**: ≥90% CORRECT, ≤5% INCORRECT
**Red Flag**: <70% CORRECT, >20% INCORRECT (indicates algorithm issues)

## 🐛 Known Issues and Workarounds
### Issue 1: CSV Encoding in Excel
**Problem**: Non-ASCII characters display incorrectly
**Solution**: Open with UTF-8 encoding explicitly
### Issue 2: Long URLs Break Spreadsheet
**Problem**: wikidata_url column too wide
**Solution**: Hide column, use click-through instead
### Issue 3: Progress Checker Shows 0%
**Problem**: validation_status not recognized
**Solution**: Use EXACT caps: `CORRECT`, `INCORRECT`, `UNCERTAIN`
### Issue 4: Can't Decide Status
**Problem**: Ambiguous match
**Solution**: Mark `UNCERTAIN`, add detailed notes, flag for expert
