Wikipedia exists in more than 300 languages, but half of them have fewer than 10 active contributors. That’s created enormous discrepancies in quality and accuracy, for example, a local language in the Philippines still listing Dianne Feinstein as mayor of San Francisco. But entries in other languages betray a political agenda: Until recently, Croatian Wikipedia referred to a concentration camp in Nazi-allied Croatia during World War II as a “collection camp.” Wikipedia has announced an effort to address the problem with a language-independent project called Wikifunctions. Marco Werman speaks with Denny Vrandečić, head of special projects at Wikimedia Foundation, the nonprofit that owns and operates Wikipedia.
