## Workflow Efficiency
|
|
|
|
### European Enrichment Pipeline (Optimized)
|
|
1. **Load/Parse ISIL Registry** → LinkML YAML format (1 min)
|
|
2. **Fetch OSM Data** → Overpass API query (8-15 sec)
|
|
3. **Query Wikidata** → SPARQL endpoint (10-20 sec)
|
|
4. **Fuzzy Match** → RapidFuzz token_sort_ratio (5-10 sec)
|
|
5. **Generate Enriched YAML** → Apply enrichments (2 sec)
|
|
6. **Export to RDF** → JSON-LD + Turtle (2 sec)
|
|
7. **Create Report** → Markdown documentation (1 min)
|
|
|
|
**Total per country**: 25-45 minutes (after pipeline optimization)
|
|
|
|
### Japanese Fast-Track Pipeline
|
|
1. **Parse CSVs** → Direct LinkML conversion (5 min for 12k records)
|
|
2. **Skip enrichment** → Too large for single-query approach
|
|
3. **Export to RDF** → Pending (would take ~30 sec)
|
|
|
|
**Total**: 5 minutes parsing (enrichment requires batch strategy)
|
|

## Technical Achievements
|
|
|
|
### Reusable Components
|
|
✅ **OSM Overpass Query Template** - Works for any country
|
|
✅ **Wikidata SPARQL Template** - Supports 150+ languages
|
|
✅ **Fuzzy Matching Algorithm** - Handles Cyrillic, Japanese, multilingual
|
|
✅ **LinkML Export Pipeline** - YAML → JSON-LD → Turtle
|
|
✅ **Automated Report Generation** - Markdown with statistics
|
|
|
|
### Data Quality Features
|
|
✅ **Match Confidence Scoring** - High (≥85%), Medium (75-84%), Low (<75%)
|
|
✅ **Provenance Tracking** - Data source, tier, extraction method, timestamps
|
|
✅ **GHCID Generation** - Persistent identifiers for all institutions
|
|
✅ **Schema Compliance** - LinkML v0.2.1 validation
|
|
|
|
### Multilingual Support

## Key Insights
|
|
|
|
### 1. Wikidata Coverage Varies Widely
|
|
- **High**: Austria (4,863 entities), Belgium (2,799)
|
|
- **Medium**: Bulgaria (2,824 entities but only 8.5% match rate)
|
|
- **Low**: Belarus (32 entities)
|
|
- **Unknown**: Japan (not queried yet, but expect 5,000+ entities)
|
|
|
|
**Implication**: Enrichment rates depend more on **match quality** than corpus size. Bulgaria has a large corpus but poor name matching.
|
|
|
|
### 2. ISIL Registry Quality
|
|
- **Excellent**: Japan (standardized, complete, English names)
|
|
- **Good**: Austria, Belgium, Bulgaria (complete addresses, websites)
|
|
- **Moderate**: Belarus (basic information only)
|
|
|
|
**Implication**: Japanese ISIL registry is the gold standard - clean CSV, English names, structured addresses.
|
|
|
|
### 3. Institution Type Distribution
|
|
- **Europe**: Balanced (35-40% libraries, 30-35% museums, 20-30% archives)
|
|
- **Japan**: Library-dominated (64% libraries vs 34% museums, 1% archives)
|
|
|
|
**Implication**: Japan has comprehensive public library coverage, less archival documentation in ISIL.
|
|
|
|
### 4. Enrichment ROI
|
|
- **High ROI**: Belgium (56.5% enrichment, 45 min effort)
|
|
- **Medium ROI**: Austria (48.0% enrichment, 1 hr effort)
|
|
- **Low ROI**: Bulgaria/Belarus (16-18% enrichment, 30 min - 3 hr effort)
|
|
|
|
**Implication**: Countries with strong Wikidata documentation and ISIL-Wikidata cross-linking provide best enrichment returns.

## Next Steps
|
|
|
|
### Immediate Options
|
|
|
|
#### Option 1: Enrich Japan (Long Task)
|
|
**Estimated Time**: 3-5 hours
|
|
**Expected Results**: 4,000-6,000 enriched institutions (40-50% rate)
|
|
|
|
**Challenges**:
|
|
- Massive Wikidata query (may timeout)
|
|
- OSM query needs regional batching (47 prefectures)
|
|
- Fuzzy matching on 12k records computationally intensive
|
|
|
|
**Strategy**:
|
|
- Batch by prefecture (47 batches)
|
|
- Cache OSM/Wikidata results
|
|
- Parallel processing
|
|
|
|
#### Option 2: Continue European Series
|
|
**Next Targets**:
|
|
- **France** - 400-600 institutions, expected 55-65% enrichment
|
|
- **Germany** - 500-800 institutions, expected 60-70% enrichment
|
|
- **Netherlands** - Already have data, needs integration
|
|
- **Scandinavia** (Norway, Sweden, Denmark, Finland) - 100-300 each
|
|
|
|
#### Option 3: Process Conversation Files (TIER_4 Data)
|
|
**Estimated Time**: 3-5 hours
|
|
**Expected Results**: 2,000-5,000 global institutions extracted from 139 conversation JSONs
|
|
|
|
**Challenges**:
|
|
- NLP extraction less reliable than CSV parsing
|
|
- Requires validation and deduplication
|
|
- Lower data quality (TIER_4 vs TIER_1)
|

## Recommendations
|
|
|
|
### 1. Export Japan to RDF
|
|
**Priority**: High
|
|
**Effort**: 5 minutes
|
|
**Reason**: Complete the dataset with JSON-LD and Turtle exports
|
|
|
|
### 2. Enrich Japan (Prefecture-by-Prefecture)
|
|
**Priority**: Medium
|
|
**Effort**: 3-5 hours
|
|
**Reason**: Unlock massive value (12k institutions → 5k+ enriched)
|
|
**Strategy**: Batch by prefecture to avoid API timeouts
|
|
|
|
### 3. Continue European Series
|
|
**Priority**: High
|
|
**Effort**: 1-2 hours per country
|
|
**Reason**: Maintain momentum, excellent enrichment rates
|
|
|
|
### 4. Create Master Index
|
|
**Priority**: Medium
|
|
**Effort**: 30 minutes
|
|
**Reason**: Single entry point for all 13k institutions
|
|
