Example Entry from YAML

- label: Q9259
  hypernym:
    - heritage site
  type:
    - B
    - F
    - L
    - A
    - M
  duplicate:
    - Q31838911  # Alternative Wikidata ID for same entity

Impact on Query Generation

When generating SPARQL queries, both the primary label and duplicate Q-numbers are excluded:

FILTER(?hyponym NOT IN (
  wd:Q9259,      # Primary ID
  wd:Q31838911,  # Duplicate ID
  ...
))

This ensures that if Wikidata search discovers the duplicate ID, it won't be returned as a "new" hyponym since we've already curated the entity under its primary ID.

Verification in Generated Query

File: botanical_query_updated_20251116T093744.sparql

All 18 duplicate Q-numbers are present in FILTER statements. You can verify with:

grep -o "wd:Q31838911\|wd:Q1257025\|wd:Q21164403\|wd:Q3457217" \
  data/wikidata/GLAMORCUBEPSXHFN/B/queries/botanical_query_updated_20251116T093744.sparql

Expected output:

wd:Q21164403
wd:Q1257025
wd:Q3457217
wd:Q21164403  # Appears twice (in different FILTER chunks)

Recommendations

Keep duplicate mappings: These are valuable for preventing rediscovery
Document reasons: When adding new duplicates, add comments explaining why
Verify Wikidata: Check if Q-numbers have been merged in Wikidata (use redirect checker)
Update regularly: As Wikidata evolves, more duplicates may emerge
