## Methodology
|
|
|
|
### Search Strategy
|
|
|
|
1. **Primary Search**: Wikidata authenticated search API
|
|
- Query format: Full Portuguese institution name
|
|
- Fallback: English translation with abbreviation
|
|
|
|
2. **Verification**: SPARQL queries when needed
|
|
- Example: UFRN required SPARQL query to disambiguate from library entity
|
|
- Query pattern: Universities (P31: Q3918) in Brazilian states (P17: Q155, P131: state)
|
|
|
|
3. **Metadata Validation**: All Q-numbers verified via `get_metadata()` API
|
|
- Confirmed Portuguese labels match expected institution names
|
|
- Verified descriptions indicate correct institution type (university, not library/archive/museum)
|
|
|
|
### Data Quality Issues Resolved
|
|
|
|
#### False Positive Corrections (from initial search)
|
|
|
|
- **UFRR initial match**: Q118133039 (Museu de Solos - Soil Museum) ❌
|
|
- **Correct match**: Q7894378 (Universidade Federal de Roraima) ✅
|
|
|
|
- **UFS initial match**: Q50811482 (Tomo - Academic journal) ❌
|
|
- **Correct match**: Q7894380 (Universidade Federal de Sergipe) ✅
|
|
|
|
- **UFRN initial match**: Q107617217 (No label/description found) ❌
|
|
- **Correct match via SPARQL**: Q3847505 (Universidade Federal do Rio Grande do Norte) ✅
|
|
|
|
### SPARQL Query Example
|
|
|
|
```sparql
|
|
SELECT ?item ?itemLabel WHERE {
|
|
?item wdt:P31 wd:Q3918 . # Instance of: university
|
|
?item wdt:P17 wd:Q155 . # Country: Brazil
|
|
?item wdt:P131* wd:Q43255 . # Located in: Rio Grande do Norte state
|
|
SERVICE wikibase:label { bd:serviceParam wikibase:language "pt,en". }
|
|
}
|
|
```
|
|
|
|
Result: `Q3847505` - Universidade Federal do Rio Grande do Norte

## Data Quality Assurance
|
|
|
|
### Verification Checklist

|
|
- ✅ Portuguese labels match expected institution names
|
|

|
|
- ✅ All institutions verified as Brazilian (country: BR)
|
|
- ✅ No duplicate Q-numbers across dataset
|
|

|
|

|
## Challenges & Solutions
|
|
|
|
### Challenge 1: False Positive Matches
|
|
|
|
**Problem**: Initial Wikidata searches returned incorrect entities:
|
|
- UFRR matched to soil museum instead of university
|
|
- UFS matched to academic journal instead of university
|
|
|
|
**Solution**:
|
|
1. Implemented metadata verification step
|
|
2. Re-searched with more specific queries (full Portuguese names)
|
|
3. Verified descriptions confirm institution type
|
|
|
|
### Challenge 2: Missing Wikidata Labels
|
|
|
|
**Problem**: UFRN initially matched Q107617217 with no label/description
|
|
|
|
**Solution**:
|
|
1. Used SPARQL query to find universities in Rio Grande do Norte state
|
|
2. Found correct entity Q3847505 with proper metadata
|
|
3. Validated via Portuguese label and state location
|
|
|
|
### Challenge 3: Abbreviation Ambiguity
|
|
|
|
**Problem**: Brazilian federal universities use standard abbreviations (UFX format) that may match multiple entities
|
|
|
|
**Solution**:
|
|
1. Always verify state/location matches expected state
|
|
2. Check description mentions "universidade federal" (federal university)
|
|
3. Use SPARQL with geographic filters when needed
|
|
|

|
|
|
|
## Lessons Learned
|
|
|
|
1. **Always verify metadata**: Search API can return partial matches; metadata validation is essential
|
|
2. **SPARQL is powerful**: When search fails, SPARQL with property filters (P31, P17, P131) yields accurate results
|
|
3. **Federal university pattern**: Brazilian federal universities follow naming convention "Universidade Federal de [State]" - use full name for better matches
|
|
4. **Empty name bug fixed**: Batch 11 fix (checking for non-empty names) prevented false positives in Batch 12

## Next Steps (Batch 13)
|
|
|
|
