  4. 4. Google had its own free and open knowledge base… Freebase
  5. 5. Google sunsets Freebase – its own structured data repository.
  6. 6. This means that Google’s ‘Knowledge Graph’ is now powered, not exclusively but ever increasingly, by Wikidata. “The primary issue with Google’s knowledge panels is that they aren’t terribly knowledgeable: They provide information but often leave out any context on where that information came from….” Caitlin Dewey, The Washington Post – 11 May 2016
  7. 7. The need for digital provenance “Since Google frequently does not cite its sources…. there’s no way for users to double-check “answers” for bias or error, which doubtlessly exist.” Caitlin Dewey, The Washington Post – 11 May 2016
  8. 8. Wikidata – the new Rosetta Stone “Data is beautiful. Data is information.”
  9. 9. Wikidata Wikidata is a free linked database of knowledge that can be read and edited by both humans and machines. Wikidata acts as central storage for the structured data of its Wikimedia sister projects including Wikipedia, Wikivoyage, Wikisource, and others.
  10. 10. ● repository of the world's knowledge ● database anyone can read and edit ● multi-lingual ● designed to deal with the reality Wikipedia has to deal with ● free and open source software. ●All data on Wikidata is CC-0 licenced. What is Wikidata actually?
  11. 11. English Wikipedia “only includes only includes 30% of the items entered in the other 287 languages.”* “The promise of linked open data seems to have finally arrived.”

  23. 23. What all this Linked Data means…. • Using Wikidata we can now query Wikipedia as never before. e.g. Show me all the architects with UK Citizenship grouped by place of education. • The Wikidata game gamifies the experience of adding an item to improve Wikidata a little at a time, simply & easily. • Inventaire builds on Wikidata by allowing people to share their favourite books, thereby adding to the open knowledge on books & authors. • The BFI, MOMA and Ted Talks are all now migrating their data to Wikidata.
