Accent Removal ``` QuΓ©bec β†’ Quebec β†’ QUE CΓ΄te Saint-Luc β†’ Cote Saint Luc β†’ COT MontrΓ©al β†’ Montreal β†’ MON ``` #### 2. Abbreviation Expansion ``` St. Albert β†’ Saint Albert β†’ SAI St-Leonard β†’ Saint Leonard β†’ SAI Ste. Marie β†’ Sainte Marie β†’ SAI Mt. Pleasant β†’ Mount Pleasant β†’ MOU ``` #### 3. Special Character Handling ``` O'LEARY β†’ Oleary β†’ OLE M'Chigeeng β†’ Mchigeeng β†’ MCH LA GRAND'TERRE β†’ La Grandterre β†’ LAG ``` #### 4. Hyphen Processing ``` Ma-Me-O Beach β†’ Mameo Beach β†’ MAM St-Andrews β†’ Saint Andrews β†’ SAI CΓ΄te-Saint-Luc β†’ Cote Saint Luc β†’ COT ``` #### 5. Leading Number Removal ``` 100 MILE HOUSE β†’ Mile House β†’ MIL ``` #### 6. Article Handling ``` LA CRETE β†’ La Crete β†’ LAC (first 2 from "La" + 1 from "Crete") Le Gardeur β†’ Legardeur β†’ LEG ``` ### Implementation Modified 3 key methods in `src/glam_extractor/parsers/canadian_isil.py`: 1. **`_remove_accents()`** - Unicode normalization to strip accent marks 2. **`_expand_abbreviations()`** - Expand St/Ste/Mt + handle hyphenated forms 3. **`_create_city_locode()`** - Remove spaces before taking 3-letter code --- ## Final Dataset Statistics ### By Institution Type | Type | Count | Percentage | |------|-------|------------| | **LIBRARY** | 4,621 | 48.3% | | **EDUCATION_PROVIDER** | 2,122 | 22.2% | | **OFFICIAL_INSTITUTION** | 1,234 | 12.9% | | **RESEARCH_CENTER** | 1,133 | 11.8% | | **ARCHIVE** | 245 | 2.6% | | **MUSEUM** | 211 | 2.2% | ### By Province | Province | Count | Percentage | |----------|-------|------------| | Ontario | 3,419 | 35.7% | | Quebec | 1,901 | 19.9% | | Alberta | 1,275 | 13.3% | | British Columbia | 925 | 9.7% | | Saskatchewan | 584 | 6.1% | | Manitoba | 530 | 5.5% | | Nova Scotia | 314 | 3.3% | | New Brunswick | 256 | 2.7% | | Newfoundland and Labrador | 218 | 2.3% | | Prince Edward Island | 59 | 0.6% | | Northwest Territories | 36 | 0.4% | | Yukon | 32 | 0.3% | | Nunavut | 17 | 0.2% | --- ## Data Quality Metrics -

Full street addresses - Phone numbers - Email addresses - Websites - Operating hours - Service descriptions **Estimated time**: ~2.5 hours for 9,566 records (1.2 sec per record) ### Task 3: Geocoding (Low Priority) Add geographic coordinates: - Latitude/longitude for all 9,566 institutions - Use Nominatim API (1 req/sec rate limit) - Cache results to avoid repeated lookups - Estimated time: ~3 hours ### Task 4: Integration (Low Priority) Merge with global GLAM dataset: - Cross-reference with conversation-extracted Canadian institutions - Deduplicate by ISIL code - Resolve conflicts (Canadian TIER_1 data is authoritative) - Update global dataset statistics --- ## Lessons Learned 1. **Unicode normalization is essential** for international data (French accents, special characters) 2. **Hyphenated abbreviations are common** in Canadian place names (St-Leonard, Ma-Me-O) 3. **Article handling matters** for short city names (La Crete, Le Gardeur) 4. **Iterative refinement works** - Start with simple rules, test, refine based on failures 5. **100% success is achievable** with comprehensive normalization --- ## Code Quality ### Parser Features (Final) βœ… Accent removal (Γ© β†’ e, Γ΄ β†’ o, etc.) βœ… Abbreviation expansion (St. β†’ Saint) βœ… Hyphenated abbreviations (St-Leonard β†’ Saint Leonard) βœ… Apostrophe handling (O'Leary β†’ Oleary) βœ… Leading number removal (100 Mile House β†’ Mile House) βœ… Article detection (La, Le, Les) βœ… Space removal for LOCODE generation βœ… Fallback to word initials for short names βœ… Padding with X for names < 3 chars ### Test Coverage -
