Revision as of 12:16, 19 May 2007 by 121.152.186.68 (talk)

Wikipedia (IPA: /ˌwikiˈpiːdi.ə/, /ˌwɪkiˈpiːdi.ə/, or /ˌwaɪkiˈpiːdi.ə/ (Audio (U.S.) (help·info)) is a multilingual, web-based, free content encyclopedia project. Wikipedia is written collaboratively by volunteers; the vast majority of its articles can be edited by anyone with access to the Internet. Wikipedia's name is a portmanteau of the words wiki (a type of collaborative website) and encyclopedia. Its main servers are in Tampa, Florida, with additional servers in Amsterdam and Seoul.

Wikipedia's English edition was launched on January 15, 2001, as a complement to Nupedia, an expert-written and now defunct encyclopedia. The project is currently operated by the Wikimedia Foundation, a non-profit organization created by Jimmy Wales, the co-founder of Wikipedia.[2][3][4][5][6] Wikipedia has approximately 7.2 million articles in 251 languages,[1] 1.7 million of which are in the English edition. It has steadily risen in popularity since its inception,[7] and currently ranks among the top fifteen most-visited websites worldwide.[8]

Due to its open nature, critics have questioned Wikipedia's reliability and accuracy.[9] The site has also been criticized for its susceptibility to vandalism,[10] uneven quality, systemic bias and inconsistencies,[11] and for favoring consensus over credentials in its editorial process.[12] Wikipedia's content policies[13] and sub-projects set up by contributors seek to address these concerns.[14] Two scholarly studies have concluded that vandalism is generally short-lived[15] and that Wikipedia is generally as accurate as other encyclopedias.[16]

Authorship and management

During December 2005, about 27,000 users made at least five edits to Wikipedia; of these, 17,000 worked on the English edition.[17] Maintenance tasks are performed by a group of volunteers; these include developers, who work on the MediaWiki software, and other trusted users with various permission levels including "steward", "bureaucrat" and "administrator".[18] Administrators are the largest group of specially privileged users, and have the ability to delete (remove) pages, lock articles from being changed, and prevent users from editing.[19]

Wikipedia is funded through the Wikimedia Foundation. Its 4th Quarter 2005 costs were $321,000 USD, with hardware making up almost 60% of the budget.[20] The Wikimedia Foundation currently relies primarily on private donations, and holds regular fundraisers;[21] the January 2007 fundraiser raised just over $1 million.[22]

Software and hardware

 
 
Wikipedia receives between 10,000 and 30,000 page requests per second, depending on time of day.[23] More than 100 servers have been set up to handle the traffic.

The operation of Wikipedia depends on MediaWiki, a custom-made, open source wiki software platform written in PHP and built upon the MySQL database. The software incorporates modern programming features, such as a macro language, variables, a transclusion system for templates, and URL redirection. MediaWiki is licensed under the GNU General Public License and used by all Wikimedia projects, as well as many other wiki projects. Originally, Wikipedia ran on UseModWiki written in Perl by Clifford Adams (Phase I), which initially required CamelCase for article hyperlinks; the present double brackets were incorporated later. Starting in January 2002 (Phase II), Wikipedia began running on a PHP wiki engine with a MySQL database; this software was custom-made for Wikipedia by Magnus Manske. The Phase II software was repeatedly modified to accommodate the exponentially increasing demand. In July 2002 (Phase III), Wikipedia shifted to the third-generation software, MediaWiki, originally written by Lee Daniel Crocker.

 
 
Overview of system architecture, May 2006. Source: layout diagrams Server layout diagrams on Meta-Wiki.

Wikipedia runs on dedicated clusters of Linux servers in Florida and in four other locations.[24] Wikipedia employed a single server until 2004, when the server setup was expanded into a distributed multitier architecture. In January 2005, the project ran on 39 dedicated servers located in Florida. This configuration included a single master database server running MySQL, multiple slave database servers, 21 web servers running the Apache HTTP Server, and seven Squid cache servers. By September 2005, its server cluster had grown to around 100 servers in four locations around the world.

Page requests are first passed to a front-end layer of Squid caching servers. Requests that cannot be served from the Squid cache are sent to load-balancing servers running the Perlbal software, which in turn pass the request to one of the Apache web servers for page-rendering from the database. The web servers deliver pages as requested, performing page rendering for all the language editions of Wikipedia. To increase speed further, rendered pages for anonymous users are cached in a filesystem until invalidated, allowing page rendering to be skipped entirely for most common page accesses. To further accelerate response times, Wikimedia is building a global network of caching servers, beginning with three caching servers in France. Two larger clusters in the Netherlands and Korea now handle much of Wikipedia's traffic load.

Language editions

See also: List of Wikipedias
 
 
Wikipedia in Hebrew.[25]

Wikipedia has been described as "an effort to create and distribute a free encyclopedia of the highest possible quality to every single person on the planet in their own language".[26] There are presently 251 language editions of Wikipedia; of these, the top 14 have over 100,000 articles and the top 132 have over 1,000 articles.[1]

Since Wikipedia is web-based, therefore world-wide, contributors of a same language edition may use different dialects or may come from different countries (this is the case for the English edition). These differences may lead to some conflicts about spelling[27] or points of view[28]. According to Alexa Internet's audience measurement service, the English subdomain (en.wikipedia.org) receives approximately 55% of Wikipedia's cumulative traffic, with the remaining 45% split among the other languages.[7]

Though the various language editions are held to global policies such as "neutral point of view," they diverge on some points of policy and practice. It is most notably the case for the use of non-free images.[29]

Coordination and translation

Though each language editions are more or less independent, some efforts are made to supervise them all. They are coordinated in part by Meta-Wiki, the Wikimedia Foundation's wiki devoted to maintaining all of its projects (Wikipedia and others). For instance, Meta-Wiki provide important statistics on all language editions of Wikipedia and maintain a list of articles every Wikipedia should have. This list concerns basic content like science, history, geography, etc. As for the rest, it is not rare articles for strongly related to a particular language do not have their counterparts in another edition. For example, articles about small townships of the United States might only be available in English.

Multilingual editors of sufficient fluency are encouraged to translate articles manually; automated translation of articles is explicitly disallowed.[30] Translated articles represent only a small portion of articles in most editions.[31] Articles available in more than one language may offer "InterWiki" links in their left margins, which link to the counterpart articles in other editions. Images and other non-verbal media are shared among the various language editions through the Wikimedia Commons repository. Beyond translations, some multingual efforts are also realised thanks to the multilingual coordination.

Reliability and bias

Main article: Reliability of Wikipedia

Wikipedia appeals to the authority of peer-reviewed publications rather than the personal authority of experts.[32] Wikipedia does not require that its contributors give their legal names[33] or provide other information to establish their identity.[34] Although some contributors are authorities in their field, Wikipedia requires that even their contributions be supported by published sources.[32]

Wikipedia tries to address the problem of systemic bias, and to deal with zealous editors who seek to influence the presentation of an article in a biased way, by insisting on a neutral point of view.[35] The English-language Wikipedia has introduced a scale against which the quality of articles is judged;[36] other editions have also adopted this. Roughly 1200 articles have passed a rigorous set of criteria to reach the highest rank, "featured article" status; such articles are intended to provide a thorough, well-written coverage of their topic, and be supported by many references to peer-reviewed publications.[37]

Academic evaluation

Some studies suggest that Wikipedia provides a good starting point for research, but sometimes suffers from significant omissions and inaccuracies.[38] On the other hand, an investigation by Nature comparing Wikipedia to the Encyclopædia Britannica suggested a near similar level of accuracy in terms of its natural science articles.[39] Encyclopædia Britannica Inc. disagreed and described this study as "fatally flawed",[40] to which Nature later responded, stating that its study was perfectly neutral.[41] Other studies have concluded that Wikipedia's coverage of history is significantly broader and deeper than that of Encarta, while being just as accurate,[16] and that obvious vandalism is usually reverted quickly.[15]

In a study of Wikipedia as a community, economics PhD student Andrea Ciffolilli argued that the low transaction costs of participating in wiki software create a catalyst for collaborative development, and that a "creative construction" approach encourages participation.[42]

In February 2007, an article in The Harvard Crimson newspaper reported that some of the professors at Harvard University do include Wikipedia in their syllabi, but that there is a split in their perception of using Wikipedia.[43]

Criticism and controversy

Main article: Criticism of Wikipedia

Wikipedia has been accused of exhibiting systemic bias and inconsistency;[9] critics argue that Wikipedia's open nature, and favouring consensus over credentials in its editorial process, makes it unauthoritative, and that a lack of proper sources for much of the information makes it unreliable.[44] Some commentators suggest that Wikipedia is usually reliable, but that it is not always clear how much.[12] The project's preference for consensus over credentials has been labelled "anti-elitism".[11] Editors of traditional reference works such as the Encyclopædia Britannica have questioned the project's utility and status as an encyclopedia.[45] Many university lecturers discourage students from citing any encyclopedia in academic work, preferring primary sources;[46] some specifically prohibit Wikipedia citations.[47] Co-founder Jimmy Wales stresses that encyclopedias of any type are not usually appropriate as primary sources, and should not be relied upon as authoritative.[48] Technology writer Bill Thompson commented that the debate was possibly "symptomatic of much learning about information which is happening in society today."[49]

Concerns have also been raised regarding the lack of accountability that results from users' anonymity,[50] and that it is vulnerable to vandalism and Internet trolls.[51] For example, false information was introduced into the biography of John Seigenthaler, Sr. and remained undetected for four months.[52]

Wikipedia's community has been described as "cult-like",[53] although not always with entirely negative connotations,[54] and criticised for failing to accommodate inexperienced users.[55] The addition of political spin to articles by organizations including the U.S. House of Representatives and special interest groups[10] has been noted,[56] and organizations such as Microsoft have offered financial incentives to work on certain articles.[57] Wikipedia has been parodied by its critics, notably by Stephen Colbert in The Colbert Report.[58]

In 2007, the Wikipedia article on then-Montana senator Conrad Burns was edited by his own staff, causing political scandal among his constituents.[59]

Wikipedia's content policies[13] and sub-projects set up by contributors seek to address these concerns.[60] Several scholarly studies have concluded that vandalism is generally short-lived,[15] and that Wikipedia is roughly as accurate as other online encyclopedias.[16]

Due to Wikipedia's openness, it is a prime target for trolls who, with intent, add misleading, sometimes biased information to articles or delete or reword neutral in tone information from articles, occasionally, carry on a seemingly never ending conversation in article discussion rooms, and draw undue attention to themselves.[61][62]

Awards

Wikipedia won two major awards in May 2004.[63] The first was a Golden Nica for Digital Communities of the annual Prix Ars Electronica contest; this came with a €10,000 (£6,588; $12,700) grant and an invitation to present at the PAE Cyberarts Festival in Austria later that year. The second was a Judges' Webby Award for the "community" category.[64] Wikipedia was also nominated for a "Best Practices" Webby. In September 2004, the Japanese Wikipedia was awarded a Web Creation Award from the Japan Advertisers Association. This award, normally given to individuals for great contributions to the Web in Japanese, was accepted by a long-standing contributor on behalf of the project.

In a 2006 Multiscope research study, the Dutch Wikipedia was rated the third best Dutch language site, after Google and Gmail, with a score of 8.1.[65] On 26 January 2007, Wikipedia was also awarded the fourth highest brand ranking by the readers of brandchannel.com, receiving 15% of the votes in answer to the question "Which brand had the most impact on our lives in 2006?"[66] Founder Jimmy Wales was named one of the 100 most influential people in the world by TIME Magazine in 2006.[67] In 2006, the Russian Wikipedia won the "Science and education" category of the "Runet Prize" (Russian: Премия Рунета) award, supervised[68] by the Russian government agency FAPMC.

In the media

Main article: Wikipedia in popular culture

Wikipedia's content has been mirrored and forked by hundreds of sites including database dumps. Its content has also been used in academic studies, books, conferences and court cases.[69][70] The Canadian Parliament website refers to Wikipedia's article on same-sex marriage in the "related links" section of its "further reading" list for Civil Marriage Act.[71] The encyclopedia's assertions are increasingly used as a source by organizations such as the U.S. Federal Courts and the World Intellectual Property Office[72] — though mainly for supporting information rather than information decisive to a case.[73] Wikipedia has also been used as a source in journalism,[74] sometimes without attribution; several reporters have been dismissed for plagiarizing from Wikipedia.[75][76]

With increased usage and awareness, there have been an increasing number of references to Wikipedia in popular culture. Many parody Wikipedia's openness, with characters vandalizing or modifying the online encyclopedia project's articles. Uncyclopedia is the largest such website; its Main Page claims that it is the "content-free encyclopedia that anyone can edit,"[77] parodying the English Wikipedia's welcome message on its Main Page.

In the episode "Wikiality" of The Colbert Report, host Stephen Colbert has instigated his viewers to vandalize articles in humorous ways, once doing so on the Wikipedia article on elephants.[78] "Weird Al" Yankovic's character in his video 'White & Nerdy' is seen vandalising the entry for the Atlantic record label with the exclamation "You suck!," after they rescinded permission for a parody.[79]

In a recent episode of American Dad (entitled Black Mystery Month), protagonists Stan Smith and Steve Smith fail to reveal to the world that George Washington Carver wasn't the person who invented peanut butter, then create a Wikipedia page entitled "The Truth About Peanut Butter" to inform the world, citing that it is the one place you can put crazy information out with no evidence and still have millions of people believe it to be true.

In "The Negotiation" episode of The Office, Michael prints out a list of negotiation tactics and praises Wikipedia, calling it "the best thing ever." However, his comment that, "anyone anywhere in the world can edit it, so you know you're getting the best information possible," can be seen as sarcasm on the part of the show's writers.

Related projects

Wikipedia has spawned several sister projects. The first, "In Memoriam: September 11 Wiki",[80] created in October 2002,[81] detailed the September 11, 2001 attacks; this project was closed in October 2006.[82] Wiktionary, a dictionary project, was launched in December 2002;[83] Wikiquote, a collection of quotations, a week after Wikimedia launched, and Wikibooks, a collection of collaboratively written free books, the next month. Wikimedia has since started a number of other projects.[84]

A similar non-wiki project, the GNUpedia project, co-existed with Nupedia early in its history; however, it has been retired and its creator, free-software figure Richard Stallman, has lent his support to Wikipedia.[85]

Other websites centered around collaborative knowledge base development have drawn inspiration from or inspired Wikipedia. Some, such as Susning.nu, Enciclopedia Libre, and WikiZnanie likewise employ no formal review process, whereas others use more traditional peer review, such as the expert-written Stanford Encyclopedia of Philosophy, h2g2 and Everything2.

Another wiki project, the Conservapedia, is based on the Wikipedia software platform (Mediawiki), and it draws from the basic principles of the Wikipedia, but it is intended to address what is perceived and denounced as Wikipedia's liberal bias.

Fork of Citizendium

According to a statement made by Jimmy Wales, who is the current de-facto leader of Wikipedia,[86] "We welcome a diversity of efforts," he said when he was referring to the Citizendium project in an interview. "If Larry's project is able to produce good work, we will benefit from it by copying it back into Wikipedia."[87]
