P17: Translation History
  1. WDProp:
    • Collaborative Multilingual Multi-domain Ontology development: is it possible to achieve a truly multilingual experience?
  2. Goals:
    • Understanding Wikidata property proposal, creation and translation
    • Available templates and their usage
    • Providing real-time statistics to (multilingual) contributors
  • WDProp
    • Get real-time translation statistics
    • Navigate supported languages, properties, datatypes, classes
    • Compare translation statistics
    • Find available properties for an entity
    • Uses Wikidata SPARQL endpoints and Mediawiki API
  • URL

  • Conclusion:
    • Wikidata properties form the foundation of Wikidata knowledge base
    • Though few in number (around 5200) compared to items (around 50 million), their creation and evolution needs to be fully understood
    • Recommendation for translation to contributors
