A wiki is a
website on
which users
collaboratively modify content and structure directly from the
web
browser. In a typical wiki, text is written using a simplified
markup language and often edited with the help of a
rich-text editor.[1]
A wiki is run using
wiki
software, otherwise known as a wiki engine. A wiki engine is a type of
content management system, but it differs from most other such systems,
including
blog software, in that the content is created without any defined owner or
leader, and wikis have little inherent structure, allowing structure to emerge
according to the needs of the users.[2]
There are dozens of different wiki engines in use, both standalone and part of
other software, such as
bug tracking systems. Some wiki engines are
open source, whereas others are
proprietary. Some permit control over different functions (levels of
access); for example, editing rights may permit changing, adding, or removing
material. Others may permit access without enforcing access control. Other rules
may be imposed to organize content.
The online encyclopedia project
Wikipedia
is the most popular wiki-based website, and is one of the most widely viewed
sites in the world, having been ranked in the top ten since 2007.[3]
Wikipedia is not a single wiki but rather a collection of hundreds of wikis,
with each one pertaining to a specific language. In addition to Wikipedia, there
are tens of thousands of other wikis in use, both public and private, including
wikis functioning as
knowledge management resources,
notetaking tools,
community websites, and
intranets.
The English-language Wikipedia has the largest collection of articles; as of
September 2016, it had over five million articles.
Ward Cunningham, the developer of the first wiki software,
WikiWikiWeb, originally described it as "the simplest online database that
could possibly work".[4]
"Wiki"
(pronounced
[ˈwiki][note
1]) is a
Hawaiian word meaning "quick".[5][6][7]

Undated: Wikipedia is a multilingual,
web-based, free
encyclopedia based on a model of openly editable and viewable content, a
wiki. It is the
largest and most popular general reference work on the
World Wide Web,[3][4][5]
and is one of the most popular websites by
Alexa rank.[6]
It is owned and supported by the
Wikimedia Foundation, a
non-profit organization that operates on money it receives from donors.[7][8][9]
Wikipedia was launched on January 15, 2001, by
Jimmy
Wales and
Larry
Sanger.[10]
Sanger coined its name,[11][12]
as a portmanteau of wiki[notes
3] and "encyclopedia". Initially an English-language
encyclopedia, versions in other languages were quickly developed. With
5,802,429 articles,[notes
4] the
English Wikipedia is the largest of the more than 290 Wikipedia
encyclopedias. Overall, Wikipedia comprises more than 40 million articles in 301
different languages[14]
and by February 2014 it had reached 18 billion page views and nearly 500 million
unique visitors per month.[15]
In 2005,
Nature published a peer review comparing 42 science articles from
Encyclopædia Britannica and Wikipedia and found that Wikipedia's level
of accuracy approached that of Britannica.[16]
Time magazine stated that the open-door policy of allowing anyone to
edit had made Wikipedia the biggest and possibly the best encyclopedia in the
world, and was a testament to the vision of Jimmy Wales.[17]
Wikipedia
has been criticized for exhibiting
systemic bias, for presenting a mixture of "truths, half truths, and some
falsehoods",[18]
and for being subject to manipulation and
spin in controversial topics.[19]
In 2017,
Facebook announced that it would help readers detect
fake news
by suitable links to Wikipedia articles.
YouTube
announced a similar plan in 2018.[20]
