Wikipedia
A free-content, multilingual online encyclopedia operated by the Wikimedia Foundation.
Timeline (last 90 days)
English Wikipedia has more than 6.5 million articles, while some language editions have only hundreds of thousands.
The study's testing scope spanned five Wikipedia language editions and five academic literature datasets.
After Edward Snowden's exposure of the PRISM program in 2013, Wikipedia page views for multiple privacy-sensitive terms in the United States showed a quantifiable decline
Prior research has almost exclusively relied on popularity-based metrics to determine whether an entity is rare, most typically Wikipedia page views.
The community launched three petitions in support of unionization: an English Wikipedia solidarity petition, a global solidarity petition on Meta-Wiki, and a petition demanding that the board reverse its decision.
The Wikimedia Foundation employs a two-tier governance structure: volunteer communities are responsible for content production, while a professional staff team handles technical and operational support, and staff members cannot use their authority to intervene in editorial decisions about encyclopedia content.
MediaWiki is the core technical infrastructure underpinning Wikipedia and its sister projects; it is an open-source wiki engine written in PHP, originally developed by Magnus Manske in 2002.
Foundation staff may not use their authority to interfere with editorial decisions regarding encyclopedic content, which is an important principle for maintaining Wikipedia's neutrality and community self-governance.
The vast majority of content on Wikipedia is contributed by more than 300,000 active volunteer editors worldwide, and Foundation employees themselves do not directly write encyclopedia content.
Wikipedia uses the CC BY-SA license, which requires all derivative content to remain open.
