Data Quality Assessment

Strengths ✅

  1. Clean extraction: No malformed data, all bindings valid
  2. Good language diversity: 39 languages captured
  3. European completeness: Strong coverage of French, German, Italian, Spanish gallery terms
  4. Commercial gallery detail: Captures fine-grained commercial gallery taxonomy

Weaknesses ⚠️

  1. Low class count: 110 classes is small compared to expectations (200-300)
  2. Limited Asian terms: Japanese/Chinese gallery terminology underrepresented
  3. Kunsthalle label issue: German "Kunsthalle" not appearing despite query targeting it
  4. Vocabulary gaps: Missing regional gallery types (e.g., Southeast Asian art spaces)

Recommendations 🎯

  1. Investigate kunsthalle query: Check why Q17431399 results don't include "Kunsthalle" label
  2. Exa web research: Focus on:
    • Japanese: 画廊 (garō), ギャラリー (gyararī)
    • Chinese: 画廊 (huàláng), 艺术空间 (yìshù kōngjiān)
    • Arabic: معرض فني (maerid faniun)
    • Southeast Asian gallery terms
  3. Expand root classes: Consider adding:
    • Q2424752 (art space)
    • Q1568756 (exhibition space)
    • Contemporary art venue types

Next Steps

  1. ✅ G (GALLERY) extraction complete
  2. ⏳ Update master checklist - Mark G as complete
  3. ⏳ Proceed to O (OFFICIAL_INSTITUTION) - Government heritage agencies
  4. ⏳ Plan Exa research - Compile gaps from all completed classes
