Wikidata - A machine readable Wikipedia of linked open knowledge

Denny Vrandečić


Wikidata is Wikipedia's knowledge base, collecting multilingual structured data and made freely available to everyone. It connects millions of items, provides access to their connections in a machine-readable format and connects to the Hypertext Web and beyond for sources and references. Wikidata is Wikimedia's fastest growing project, and invites everyone to connect and link their own knowledge bases to Wikidata.


Denny Vrandečić is director of the Wikidata project at Wikimedia Deutschland. He received a PhD at the Institute AIFB at the Karlsruhe Institue of Technology KIT and was a researcher at the Laboratory of Applied Ontology LOA in Rome and the Information Sciences Institute ISI at the University of Southern California USC in Los Angeles. He co-developed Semantic MediaWiki, consulted Freebase, was the founding administrator of the Croatian Wikipedia, founding member of the Wikimedia Research Council, co-organizer of several workshops at WWW and ISWC, and co-chair of tracks at Wikimania, ESWC, and AAAI. He worked in the EU-funded projects SEKT, ACTIVE, and RENDER, project Halo funded by Vulcan Inc., and the BMBF-funded projects SMART and Cora.
