Enrichment Methodology

Fuzzy Matching Algorithm

Tool: RapidFuzz library (token_sort_ratio)
Threshold: ≥75% similarity
Priority: ISIL code match > Wikidata name match > OSM name match

Matching Process:

ISIL Code Match (Highest Priority)
- Direct comparison of ISIL codes in Wikidata
- 100% confidence score
- Result: 12 exact ISIL matches
Wikidata Name Match (Medium Priority)
- Fuzzy comparison of institution names
- Token-based scoring (word order independent)
- German language support
- Result: 81 fuzzy name matches (75-98% similarity)
OSM Name Match (Lowest Priority)
- Fuzzy comparison with OSM location names
- Used when Wikidata match fails
- Result: 14 OSM matches (75-88% similarity)

Match Score Distribution

Score Range	Count	Percentage
100% (ISIL exact)	12	11.2%
90-99%	48	44.9%
85-89%	17	15.9%
80-84%	18	16.8%
75-79%	12	11.2%

Confidence Scoring

Formula: confidence = 0.75 + (match_score - 75) / 100

Result Distribution:

High confidence (≥0.90): 60 institutions (56.1%)
Medium confidence (0.80-0.89): 35 institutions (32.7%)
Low confidence (0.75-0.79): 12 institutions (11.2%)

6-10. (Additional major institutions with high enrichment quality)

Unenriched Institutions (116 remaining, 52.0%)

Why Some Institutions Lack Enrichment

1. Small Local Libraries (42 institutions)

Municipal/community libraries without Wikidata presence
Example: "Gemeindebücherei Schattendorf" (AT-10612001BUE)
Recommendation: Manual enrichment via institutional websites

2. School Libraries (28 institutions)

Educational institution libraries, not typically in Wikidata
Example: Various school libraries across Austrian states
Recommendation: Low priority for enrichment

3. Specialized Archives (23 institutions)

Corporate, religious, or private archives
Limited online documentation
Example: Monastery archives, company archives
Recommendation: Direct contact with institutions

4. Low Match Quality (<75% similarity) (15 institutions)

Name variations too different for fuzzy matching
Example: Abbreviations vs. full names
Recommendation: Manual review and matching

5. Recent Additions (8 institutions)

Newly registered ISIL codes
Not yet documented in OSM/Wikidata
Recommendation: Wait 6-12 months, re-enrich

Regional Coverage

Austrian States (Bundesländer)

Note: ISIL codes encode location in prefix (e.g., AT-20xxx = Carinthia)

State	ISIL Prefix	Total	Enriched	Rate
Vienna	AT-OeNB, AT-UBW	45	28	62.2%
Lower Austria	AT-30xxx	38	19	50.0%
Upper Austria	AT-40xxx	32	17	53.1%
Styria	AT-60xxx	29	13	44.8%
Tyrol	AT-70xxx	24	10	41.7%
Salzburg	AT-50xxx	18	8	44.4%
Carinthia	AT-20xxx	15	5	33.3%
Vorarlberg	AT-80xxx	12	4	33.3%
Burgenland	AT-10xxx	10	3	30.0%

Observation: Urban centers (Vienna, Lower Austria, Upper Austria) have higher enrichment rates due to better Wikidata documentation.

Next Steps

Priority 1: Manual Verification (1-2 weeks)

Goal: Spot-check top 20 enriched institutions for accuracy

Process:

Visit institutional websites
Verify coordinates via Google Maps
Confirm Wikidata Q-numbers are correct institutions
Check VIAF IDs match institution names
Validate website URLs are current

Expected Corrections: 5-10% of enrichments may need adjustment

Priority 2: Wikidata Contribution (2-4 weeks)

Goal: Add ISIL codes to Wikidata entities

Actions:

For 93 matched institutions, add ISIL codes (P791 property) to Wikidata
For top 20 unenriched institutions, create Wikidata items
Add coordinates (P625) from institutional websites
Add official website links (P856)

Wikidata Property Reference:

P791: ISIL code
P625: Coordinate location
P856: Official website
P214: VIAF ID
P131: Located in the administrative territorial entity

Priority 3: Expand Enrichment (1-3 months)

Goal: Reach 70% enrichment rate (156/223 institutions)

Strategy:

Target Small Libraries (42 institutions)
- Scrape municipal websites for addresses
- Geocode addresses to coordinates
- Add institutional websites
Manual Wikidata Research (23 specialized archives)
- Search Austrian heritage databases
- Cross-reference with national archive directory
- Create Wikidata items where appropriate
Improve Fuzzy Matching (15 low-quality matches)
- Use alternative name fields
- Try German abbreviation expansion
- Manual review borderline cases (70-74% similarity)

Expected Gain: +49 institutions (+22 percentage points)

Priority 4: Integration with Global Dataset (3-6 months)

Goal: Merge Austrian data into unified GLAM database

Actions:

Apply GHCID identifier scheme (Austria prefix: AT)
Cross-link with other European datasets (Netherlands, Belgium, Germany)
Generate unified RDF knowledge graph
Export to SPARQL endpoint for federated queries
Update data/instances/europe/austria/*.yaml structure

Lessons Learned

What Worked Well ✅

Large Wikidata corpus (4,863 entities)
- Austria's cultural institutions well-documented
- Many entities already have ISIL codes (99 direct matches)
- High-quality coordinate data (97% of Wikidata entities)
Fuzzy matching algorithm
- RapidFuzz token_sort_ratio handled German language well
- Word order independence helped with institutional names
- 75% threshold balanced precision/recall
ISIL priority matching
- 12 exact ISIL matches provided 100% confidence anchors
- Reduced false positives significantly

What Could Be Improved 🔧

OSM archive/museum coverage
- Only 3 museums in OSM (vs. 1,479 in Wikidata)
- Zero archives in OSM data
- Fix: Rely primarily on Wikidata for non-library institutions
Small library coverage
- Municipal libraries rarely in Wikidata
- OSM has many, but often without Wikidata links
- Fix: Direct institutional website scraping needed
German name variations
- Abbreviations common (e.g., "Uni" vs. "Universität")
- Fuzzy matching missed some variants
- Fix: Pre-process names to expand abbreviations

Comparison with Belarus Enrichment

Factor	Austria	Belarus
Enrichment Rate	48.0%	16.2%
Wikidata Entities	4,863	32
ISIL Direct Matches	12	5
OSM Locations	748	575
Primary Limiting Factor	Small libraries	Wikidata coverage

Key Takeaway: Wikidata corpus size is the primary determinant of enrichment success. Countries with rich Wikidata documentation (Austria, Netherlands) achieve 40-50% enrichment; countries with sparse Wikidata (Belarus) achieve 15-20%.
