| − | A '''wiki''' ({{IPAc-en|audio=en-us-wiki.ogg|ˈ|w|ɪ|k|i}} {{respell|WIK|ee}}) is an application, typically a [[web application]], which allows [[Collaborative software|collaborative]] modification, extension, or deletion of its content and structure. In a typical wiki, text is written using a simplified [[markup language]] (known as "wiki markup") and a [[Online rich-text editor|rich-text editor]].<ref name="Britannica">{{citation|title=wiki|encyclopedia=[[Encyclopædia Britannica]]|volume=1|publisher=[[Encyclopædia Britannica, Inc.]]|year=2007|location=London|url=http://www.britannica.com/EBchecked/topic/1192819/wiki|accessdate=April 10, 2008}}</ref><ref name="urlEasy Wiki Hosting, Scott Hanselmans blog, and Snagging Screens">{{citation|url=http://msdn.microsoft.com/en-us/magazine/cc700339.aspx |title=Easy Wiki Hosting, Scott Hanselman's blog, and Snagging Screens |date=July 2008 |last=Mitchell |first=Scott |publisher=MSDN Magazine |accessdate=March 9, 2010}}</ref> While a wiki is a type of [[content management system]], it differs from a [[blog]] or most other such systems in that the content is created without any defined owner or leader, and wikis have little implicit structure, allowing structure to emerge according to the needs of the users.<ref name="urlEasy Wiki Hosting, Scott Hanselmans blog, and Snagging Screens"/>

| − | The encyclopedia project [[Wikipedia]] is the most popular wiki on the public web in terms of page views,<ref>[http://c2.com/cgi/wiki?TopTenWikiEngines Top Ten Wiki Engines]</ref> but there are many sites running many different kinds of [[wiki software]]. Wikis can serve many different purposes both public and private, including [[knowledge management]], [[Notetaking software|notetaking]], [[Web community|community websites]] and [[intranet]]s. 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 also be imposed to organize content.

| + | |
| − | Ward Cunningham and co-author [[Bo Leuf]], in their book ''[[The Wiki Way|The Wiki Way: Quick Collaboration on the Web]]'', described the essence of the Wiki concept as follows:<ref>{{harvnb|Leuf| Cunningham|2001 }}. See Ward Cunningham's site http://c2.com/cgi/wiki?WikiDesignPrinciples</ref><!-- page number requested -->
| + | |
| − | * A wiki invites all users to edit any [[Web page|page]] or to create new pages within the wiki Web site, using only a [[vanilla software|plain-vanilla]] Web browser without any extra [[browser extension|add-ons]].
| + | |
| − | * Wiki promotes meaningful topic associations between different pages by making page link creation almost intuitively easy and showing whether an intended target page exists or not.
| + | |
| − | * A wiki is not a carefully crafted site for casual visitors. Instead, it seeks to involve the visitor in an ongoing process of creation and collaboration that constantly changes the Web site landscape.
| + | |
| | | | |
| − | A wiki enables communities to write documents collaboratively, using a simple markup language and a web browser. A single page in a wiki website is referred to as a "wiki page", while the entire collection of pages, which are usually well interconnected by [[hyperlink]]s, is "the wiki". A wiki is essentially a database for creating, browsing, and searching through information. A wiki allows non-linear, evolving, complex and networked text, argument and interaction.<ref name=Legal>{{citation|title=Legal Issues for Wikis: The Challenge of User-generated and Peer-produced Knowledge, Content and Culture|last1 = Black | first1 = Peter | last2 = Delaney | first2 = Hayden | last3 = Fitzgerald | first3 = Brian|volume=14|publisher=eLaw J.|year=2007|url=https://elaw.murdoch.edu.au/archives/issues/2007/1/eLaw_legal%20issues%20for%20wikis.pdf}}</ref>
| + | 链接方便：通过简单的“[[条目名称]]”，可以直接产生内部链接。外部链接的引用也很方便。 |
| | | | |
| − | A defining characteristic of wiki technology is the ease with which pages can be created and updated. Generally, there is no review before modifications are accepted. Many wikis are open to alteration by the general public without requiring registration of [[User (computing)|user]] accounts. Many edits can be made in [[Real-time web|real-time]] and appear almost instantly online. However, this feature facilitates abuse of the system. Private wiki servers require [[Authentication|user authentication]] to edit pages, and sometimes even to read them.
| + | *自组织 |
| | | | |
| − | [[Maged N. Kamel Boulos]], Cito Maramba and [[Steve Wheeler]] write that the open wikis produce a process of [[Social Darwinism]]. "'Unfit' sentences and sections are ruthlessly culled, edited and replaced if they are not considered 'fit', which hopefully results in the evolution of a higher quality and more relevant page. While such openness may invite 'vandalism' and the posting of untrue information, this same openness also makes it possible to rapidly correct or restore a 'quality' wiki page."<ref name=BMC/>
| + | 自组织的：同页面的内容一样，整个超文本的相互关联关系也可以不断修改、优化。 |
| | | | |
| − | ===Editing wiki pages===
| + | 可汇聚的：系统内多个内容重复的页面可以被汇聚于其中的某个，相应的链接结构也随之改变。 |
| − | Some wikis have an "edit" button or link directly on the page being viewed, if the user has permission to edit the page. This leads to an editing page which allows participants to structure and format wiki pages with a simplified markup language, sometimes known as [[wikitext]] (for example, starting a line of text with an [[asterisk]] often sets up a [[Bullet (typography)|bulleted list]]). The style and syntax of wikitexts can vary greatly among wiki implementations,{{example needed}} some of which also allow [[HTML]] tags. Wikis favour plain-text editing, with fewer and simpler conventions than HTML, for indicating style and structure. Although limiting access to HTML and [[Cascading Style Sheets]] (CSS) of wikis limits user ability to alter the structure and formatting of wiki content, there are some benefits. Limited access to CSS promotes consistency in the look and feel, and having [[JavaScript]] disabled prevents a user from implementing code that may limit other users' access.

| + | |
| | | | |
| − | Wikis can make [[WYSIWYG]] editing available to users, usually by means of JavaScript control that translates graphically entered formatting instructions into the corresponding [[HTML element|HTML tags]] or wikitext. In those implementations, the markup of a newly edited, marked-up version of the page is generated and submitted to the server [[transparency (human-computer interaction)|transparently]], shielding the user from this technical detail. An example of this is the [[Wikipedia:VisualEditor|VisualEditor]] on Wikipedia. However, WYSIWYG controls do not always provide all of the features available in wikitext, and some users prefer not to use a WYSIWYG editor. Hence, many of these sites offer some means to edit the wikitext directly.
| + | *开放性 |
| | | | |
| − | Some wikis keep a record of changes made to wiki pages; often, every version of the page is stored. This means that authors can revert to an older version of the page, should it be necessary because a mistake has been made or the page has been vandalized. Many implementations, like [[MediaWiki]], allow users to supply an ''edit summary'' when they edit a page; this is a short piece of text summarising the changes. It is not inserted into the article, but is stored along with that revision of the page, allowing users to explain what has been done and why; this is similar to a log message when making changes to a [[revision control|revision-control]] system.
| + | 开放的：社群内的成员可以任意创建、修改、或删除页面。 |
| | | | |
| − | ===Navigation===
| + | 可观察：系统内页面的变动可以被来访者清楚观察得到。 |
| − | Within the text of most pages there are usually a large number of [[hypertext]] links to other pages. This form of non-linear navigation is more "native" to wiki than structured/formalized navigation schemes. Users can also create any number of index or table-of-contents pages, with hierarchical categorization or whatever form of organization they like. These may be challenging to maintain by hand, as multiple authors create and delete pages in an ad hoc manner. Wikis can provide one or more ways to categorize or tag pages to support the maintenance of such index pages.
| + | |
| | | | |
| − | Some wikis have a backlink feature, which displays all pages that link to a given page. It is typical in a wiki to create links to pages that do not yet exist, as a way to invite others to share what they know about a subject new to the wiki.
| + | WiKi支持面向社群的协作式写作，同时也包括一组支持这种写作的辅助工具。有人认为，Wiki系统属于一种人类知识的网络系统，我们可以在Web的基础上对Wiki文本进行浏览、创建、更改，而且这种创建、更改、及发布的代价远比HTML文本小；与此同时Wiki系统还支持那些面向社群的协作式写作，为协作式写作提供了必要的帮助；最后，Wiki的写作者自然构成了一个社群，Wiki系统为这个社群提供了简单的交流工具。与其它超文本系统相比，Wiki有使用简便且开放的优点，所以Wiki系统可以帮助我们在一个社群内共享某个领域的知识。 |
| | + | 由于Wiki的自主性，可增长以及可观察的特点，使Wiki本身也成为一个网络研究的对象。对Wiki的研究也许能够让人们对网络的认识更加深入。 |
| | + | 另外因为WiKi是一个群体协作的平台，所以它还有平等、共享的特点。 |
| | | | |
| − | ===Linking and creating pages=== | + | ==Reference== |
| − | Links are created using a specific syntax, the so-called "link pattern". Originally, most wikis{{citation needed|date=July 2013}} used [[CamelCase]] to name pages and create links. These are produced by capitalizing words in a phrase and removing the spaces between them (the word "CamelCase" is itself an example). While CamelCase makes linking very easy, it also leads to links which are written in a form that deviates from the standard spelling. To link to a page with a single-word title, one must abnormally capitalize one of the letters in the word (e.g. "WiKi" instead of "Wiki"). CamelCase-based wikis are instantly recognizable because they have many links with names such as "TableOfContents" and "BeginnerQuestions." It is possible for a wiki to render the visible anchor of such links "pretty" by reinserting spaces, and possibly also reverting to lower case. However, this reprocessing of the link to improve the readability of the anchor is limited by the loss of capitalization information caused by CamelCase reversal. For example, "RichardWagner" should be rendered as "Richard Wagner", whereas "PopularMusic" should be rendered as "popular music". There is no easy way to determine which [[capital letter]]s should remain capitalized. As a result, many wikis now have "free linking" using brackets, and some disable CamelCase by default.

| | | | |
| − | ===Searching===
| |
| − | Most wikis offer at least a title [[search algorithm|search]], and sometimes a [[Full text search|full-text search]]. The scalability of the search depends on whether the wiki engine uses a database. Some wikis, such as [[PmWiki]], use [[flat file]]s.<ref name=Augar>{{cite journal |title=Teaching and learning online with wikis |last1=Naomi |first1=Augar |first2=Ruth |last2=Raitman |first3=Wanlei |last3=Zhou |publisher=Proceedings of Beyond the Comfort Zone: 21st ASCILITE Conference |id = {{citeseerx|10.1.1.133.1456}}|year=2004}}</ref> MediaWiki's first versions used flat files, but it was rewritten by [[Lee Daniel Crocker]] in the early 2000s to be a database application. Indexed database access is necessary for high speed searches on large wikis. Alternatively, external [[Web search engine|search engines]] such as [[Google Search]] can sometimes be used on wikis with limited searching functions in order to obtain more precise results.

| − | [[Wikipedia]] became the most famous wiki site, entering the top ten most popular websites in 2007. In the early 2000s, wikis were increasingly adopted in enterprise as collaborative software. Common uses included project communication, intranets, and documentation, initially for technical users. Some [[corporate wiki|companies use wikis]] as their only collaborative software and as a replacement for static intranets, and some schools and universities use wikis to enhance [[group learning]]. There may be greater use of wikis behind [[Firewall (computing)|firewalls]] than on the public Internet.

| − | ==Implementations==
| + | |
| − | [[File:Wikipedia screenshot on Nexus 9 20141121.jpg|thumb|Homepage of Wikipedia]]
| + | |
| − | [[Wiki software]] is a type of [[collaborative software]] that runs a wiki system, allowing web pages to be created and edited using a common web browser. It may be implemented as a series of scripts behind an existing [[web server]], or as a standalone [[application server]] that runs on one or more web servers. The content is stored in a [[file system]], and changes to the content are stored in a [[relational database management system]]. A commonly implemented software package is [[MediaWiki]], which runs [[Wikipedia]]. See the [[List of wiki software]] for further information. Alternatively, [[personal wiki]]s run as a standalone application on a single computer. [[WikidPad]] is an example. Or even single local HTML file with JavaScript inside – like [[TiddlyWiki]].
| + | |
| − | | + | |
| − | Wikis can also be created on a "[[wiki farm]]", where the server side software is implemented by the wiki farm owner. [[PBwiki]], [[Socialtext]], [[Wetpaint]], and [[Wikia]] are popular examples of such services. Some wiki farms can also make private, password-protected wikis. Note that free wiki farms generally contain advertising on every page. For more information, see [[Comparison of wiki farms]].

| − | ===Controlling changes===
| + | |
| − | {{Selfref|"Recent changes" redirects here. For the Wikipedia help page, see [[Help:Recent changes]].}}
| + | |
| − | [[File:History Comparison Example (Vector).png|thumb|History comparison reports highlight the changes between two revisions of a page.]]
| + | |
| − | Wikis are generally designed with the philosophy of making it easy to correct mistakes, rather than making it difficult to make them. Thus, while wikis are very open, they provide a means to verify the validity of recent additions to the body of pages. The most prominent, on almost every wiki, is the "Recent Changes" page—a specific list numbering recent edits, or a list of edits made within a given time frame.<ref>{{harvnb|Ebersbach|2008|p=20}}</ref> Some wikis can filter the list to remove minor edits and edits made by automatic importing scripts ("[[Internet bot|bots]]").<ref>{{harvnb|Ebersbach|2008|p=54}}</ref>
| + | |
| − | | + | |
| − | From the change log, other functions are accessible in most wikis: the [[Changelog|revision history]] shows previous page versions and the [[diff]] feature highlights the changes between two revisions. Using the revision history, an editor can view and restore a previous version of the article. The diff feature can be used to decide whether or not this is necessary. A regular wiki user can view the diff of an edit listed on the "Recent Changes" page and, if it is an unacceptable edit, consult the history, restoring a previous revision; this process is more or less streamlined, depending on the wiki software used.<ref>{{harvnb|Ebersbach|2008|p=178}}</ref>
| + | |
| − | | + | |
| − | In case unacceptable edits are missed on the "recent changes" page, some wiki engines provide additional content control. It can be monitored to ensure that a page, or a set of pages, keeps its quality. A person willing to maintain pages will be warned of modifications to the pages, allowing him or her to verify the validity of new editions quickly.<ref>{{harvnb|Ebersbach|2008|p=109}}</ref> A watchlist is a common implementation of this.
| + | |
| − | | + | |
| − | Some wikis also implement "patrolled revisions", in which editors with the requisite credentials can mark some edits as not vandalism. A "flagged revisions" system can prevent edits from going live until they have been reviewed.<ref>{{citation|title=Wikipedia's Labor Squeeze and its Consequences|journal=Journal on Telecommunications and High Technology Law|last = Goldman | first = Eric|volume=8}}</ref>
| + | |
| − | | + | |
| − | ===Trustworthiness===
| + | |
| − | Critics of publicly editable wiki systems argue that these systems could be easily tampered with, while proponents argue that the community of users can catch malicious content and correct it.<ref name="Britannica"/> [[Lars Aronsson]], a data systems specialist, summarizes the controversy as follows:
| + | |
| − | | + | |
| − | {{quote|Most people, when they first learn about the wiki concept, assume that a Web site that can be edited by anybody would soon be rendered useless by destructive input. It sounds like offering free spray cans next to a grey concrete wall. The only likely outcome would be ugly graffiti and simple tagging, and many artistic efforts would not be long lived. Still, it seems to work very well.<ref name="ebersbach10"/>|}}
| + | |
| − | High editorial standards in medicine have led to the idea of expert-moderated wikis.<ref>{{citation|title=Introducing Web 2.0: wikis for health librarians |first1 = Eugene | last1 = Barsky |first2 = Dean | last2 = Giustini |date=December 2007|work=Journal of the Canadian Health Libraries Association |url=http://circle.ubc.ca/bitstream/handle/2429/497/c07-036.pdf |volume=28 |issue=4 |pages=147–150|accessdate=November 7, 2011|postscript=.}} {{ISSN|1708-6892}}</ref> Some wikis allow one to link to specific versions of articles, which has been useful to the scientific community, in that expert peer reviewers could analyse articles, improve them and provide links to the trusted version of that article.<ref>{{citation|title=Wiki ware could harness the Internet for science|first = Kevin | last = Yager | date = March 16, 2006 | url = http://www.nature.com/nature/journal/v440/n7082/full/440278a.html|bibcode=2006Natur.440..278Y|volume=440|pages=278|journal=Nature|doi=10.1038/440278a|issue=7082}}{{Subscription required}}</ref>
| + | |
| − | | + | |
| − | Noveck points out that "participants are accredited by members of the wiki community, who have a vested interest in preserving the quality of the work product, on the basis of their ongoing participation." On controversial topics that have been subject to disruptive editing, a wiki may restrict editing to registered users.<ref name=Noveck/>
| + | |
| − | | + | |
| − | ===Security===
| + | |
| − | The open philosophy of wiki – allowing anyone to edit content, does not ensure that every editor's intentions are well-mannered. For example, [[Wikipedia:Vandalism|vandalism]] (changing wiki content to something offensive, adding nonsense or deliberately adding incorrect information) can be a major problem. On larger wiki sites, such as those run by the [[Wikimedia Foundation]], [[vandalism]] ''can ''go unnoticed for some period of time. Wikis, because of their open access nature, are susceptible to intentional disruption, known as "[[troll (Internet)|trolling]]".
| + | |
| − | Wikis tend to take a ''[[soft security|soft-security]]''<ref name="soft security">{{citation|url=http://www.usemod.com/cgi-bin/mb.pl?SoftSecurity |title=Soft Security|accessdate=March 9, 2007|publisher=[[UseModWiki]]|date=September 20, 2006 }}</ref>{{Unreliable source?|date=July 2013|failed=y}} approach to the problem of vandalism, making damage easy to undo rather than attempting to prevent damage. Larger wikis often employ sophisticated methods, such as bots that automatically identify and revert vandalism and JavaScript enhancements that show characters that have been added in each edit. In this way vandalism can be limited to just "minor vandalism" or "sneaky vandalism", where the characters added/eliminated are so few that bots do not identify them and users do not pay much attention to them.<ref>{{cite web|url=http://m3m.homelinux.org/wikiMC/index.php/Security |title=Security |publisher=Assothink |accessdate=2013-02-16}}</ref>{{Unreliable source?|date=July 2013|failed=y}} An example of a bot which is used on Wikipedia to revert vandalism is ClueBot NG. ClueBot NG has the ability to revert edits, often "within minutes, if not seconds". The bot uses machine learning in lieu of heuristics.<ref>{{Cite web|url = http://www.theverge.com/2014/2/18/5412636/this-machine-kills-trolls-how-wikipedia-robots-snuff-out-vandalism|title = This machine kills trolls|date = February 18, 2014|accessdate = September 7, 2014 |publisher = The Verge|last = Hicks|first = Jesse}}</ref>

| − | The amount of vandalism a wiki receives depends on how open the wiki is. For instance, some wikis allow unregistered users, identified by their [[IP address]]es, to edit content, while others limit this function to just registered users. Most wikis allow anonymous editing without an account,<ref>{{harvnb|Ebersbach|2008|p=108}}</ref> but give registered users additional editing functions; on most wikis, becoming a registered user is a short and simple process. Some wikis require an additional waiting period before gaining access to certain tools. For example, on the [[English Wikipedia]], registered users can rename pages only if their account is at least four days old and has made at least ten edits. Other wikis such as the [[Portuguese Wikipedia]] use an editing requirement instead of a time requirement, granting extra tools after the user has made a certain number of edits to prove their trustworthiness and usefulness as an editor. [[Vandalism of Wikipedia]] is common (though policed and usually reverted) because it is extremely open, allowing anyone with a computer and Internet access to edit it, although this makes it grow rapidly. In contrast, [[Citizendium]] requires an editor's real name and short autobiography, affecting the growth of the wiki but sometimes helping stop vandalism.

| − | Edit wars can also occur as users repetitively revert a page to the version they favor. Some wiki software allows an administrator to stop such edit wars by locking a page from further editing until a decision has been made on what version of the page would be most appropriate.<ref name=Legal/>
| + | |
| − | | + | |
| − | Some wikis are in a better position than others to control behavior due to governance structures existing outside the wiki. For instance, a college teacher can create incentives for students to behave themselves on a class wiki they administer by limiting editing to logged-in users and pointing out that all contributions can be traced back to the contributors. Bad behavior can then be dealt with in accordance with university policies.<ref name=Augar/>

| − | ====Potential malware vector====
| + | |
| − | [[Malware]] can also be problem, as users can add links to sites hosting malicious code. For example, a German Wikipedia article about the [[Blaster Worm]] was edited to include a hyperlink to a malicious website. Users of vulnerable Microsoft Windows systems who followed the link would be infected.<ref name=Legal/> A countermeasure is the use of software that prevents users from saving an edit that contains a link to a site listed on a [[blacklist]] of malware sites.<ref>[[meta:Spam blacklist/About|Meta.wikimedia.org]]</ref> | + | |

| − | Wikis have found some use within the legal profession, and within government. Examples include the [[Central Intelligence Agency]]'s [[Intellipedia]], designed to share and collect [[Intelligence assessment|intelligence]], dKospedia, which was used by the [[American Civil Liberties Union]] to assist with review of documents pertaining to internment of detainees in [[Guantánamo Bay]];<ref>{{cite web|url=http://www.dailykos.com/story/2005/06/09/120607/-SusanHu-s-FOIA-Project-UPDATE|title=SusanHu's FOIA Project UPDATE|accessdate=2013-06-25}}</ref> and the wiki of the [[United States Court of Appeals for the Seventh Circuit]], used to post court rules and allow practitioners to comment and ask questions. The [[United States Patent and Trademark Office]] operates [[Peer-to-Patent]], a wiki to allow the public to collaborate on finding [[prior art]] relevant to examination of pending patent applications. [[Queens]], New York has used a wiki to allow citizens to collaborate on the design and planning of a local park.

| − | ===WikiNodes===
| + | |
| − | WikiNodes are pages on wikis that describe related wikis. They are usually organized as neighbors and delegates. A ''neighbor'' wiki is simply a wiki that may discuss similar content or may otherwise be of interest. A ''delegate'' wiki is a wiki that agrees to have certain content delegated to that wiki.<ref>{{cite web |publisher=WikiNodes |title=Frequently Asked Questions |url=http://wikinodes.wiki.taoriver.net/moin.fcg/FrequentlyAskedQuestions |archiveurl=http://web.archive.org/web/20070810213702/http://wikinodes.wiki.taoriver.net/moin.fcg/FrequentlyAskedQuestions |archivedate=August 10, 2007}}</ref>
| + | |
| − | | + | |
| − | One way of finding a wiki on a specific subject is to follow the wiki-node network from wiki to wiki; another is to take a Wiki "bus tour", for example: {{srlink|Wikipedia:TourBusStop|Wikipedia's Tour Bus Stop}}.
| + | |
| − | | + | |
| − | ===Participants===
| + | |
| − | The four basic types of users who participate in wikis are reader, author, wiki administrator and system administrator. The system administrator is responsible for installation and maintenance of the wiki engine and the container web server. The wiki administrator maintains wiki content and is provided additional functions pertaining to pages (e.g. page protection and deletion), and can adjust users' access rights by, for instance, blocking them from editing.<ref>{{cite journal |title=Analysis of the use of Wiki-based collaborations in enhancing student learning| last = Cubric | first = Marija |publisher=University of Hertfordshire |year=2007|url=https://uhra.herts.ac.uk/dspace/handle/2299/3672|accessdate=April 25, 2011}}</ref>

| − | | + | |
| − | ==Rules==
| + | |
| − | Wikis typically have a set of rules governing user behavior. Wikipedia, for instance, has a labyrinthine set of policies and guidelines summed up in its five pillars: Wikipedia is an encyclopedia; Wikipedia has a neutral point of view; Wikipedia is free content; Wikipedians should interact in a respectful and civil manner; and Wikipedia does not have firm rules. Many wikis have adopted a set of commandments. For instance, [[Conservapedia]] commands, among other things, that its editors use "[[Before Christ|B.C.]]" rather than "[[B.C.E.]]" when referring to years prior to A.D. 1 and refrain from "unproductive activity."<ref>{{vcite web|url=http://www.conservapedia.com/Conservapedia:Commandments |title=Conservapedia Commandments |work=Conservapedia.com |date=May 15, 2010 |accessdate=July 24, 2010}}</ref> One teacher instituted a commandment for a class wiki, "[[The Golden Rule|Wiki unto others as you would have them wiki unto you]]."<ref name=Augar/>
| + | |
| − | | + | |
| − | ==Legal environment==
| + | |
| − | Joint authorship of articles, in which different users participate in correcting, editing, and compiling the finished product, can also cause editors to become [[tenants in common]] of the copyright, making it impossible to republish without the permission of all co-owners, some of whose identities may be unknown due to pseudonymous or anonymous editing.<ref name=Legal/> However, where persons contribute to a collective work such as an encyclopedia, there is no joint ownership if the contributions are separate and distinguishable.<ref>{{citation |work=Redwood Music Ltd v. B Feldman & Co Ltd|year=1979|publisher=RPC 385}}</ref> Despite most wikis' tracking of individual contributions, the action of contributing to a wiki page is still arguably one of jointly correcting, editing, or compiling which would give rise to joint ownership.
| + | |
| − | | + | |
| − | Some copyright issues can be alleviated through the use of an [[open content]] license. Version 2 of the [[GNU Free Documentation License]] includes a specific provision for wiki relicensing; [[Creative Commons]] licenses are also popular. When no license is specified, an implied license to read and add content to a wiki may be deemed to exist on the grounds of business necessity and the inherent nature of a wiki, although the legal basis for such an implied license may not exist in all circumstances.{{citation needed|date=July 2013}}
| + | |
| − | | + | |
| − | Wikis and their users can be held liable for certain activities that occur on the wiki. If a wiki owner displays indifference and forgoes controls (such as banning copyright infringers) that he could have exercised to stop copyright infringement, he may be deemed to have authorized infringement, especially if the wiki is primarily used to infringe copyrights or obtains direct financial benefit, such as advertising revenue, from infringing activities.<ref name=Legal/> In the United States, wikis may benefit from [[Section 230 of the Communications Decency Act]], which protects sites that engage in "[[Good Samaritan]]" policing of harmful material, with no requirement on the quality or quantity of such self-policing.<ref>{{cite journal |title=Self-Regulation: How Wikipedia Leverages User-Generated Quality Control Under Section 230| first1 = Kathleen M. | last1 = Walsh | first2 = Sarah | last2 = Oh | date=February 23, 2010|url=http://works.bepress.com/cgi/viewcontent.cgi?article=1000&context=sarah_oh}}</ref> However, it has also been argued that a wiki's enforcement of certain rules, such as anti-bias, verifiability, reliable sourcing, and no-original-research policies, could pose legal risks.<ref>{{Citation|last = Myers | first = Ken S.|title=Wikimmunity: Fitting the Communications Decency Act to Wikipedia |journal=Harvard Journal of Law and Technology|publisher=The Berkman Center for Internet and Society|year=2008|url=http://ssrn.com/abstract=916529|volume=20|page=163}}</ref> When [[defamation]] occurs on a wiki, theoretically all users of the wiki can be held liable, because any of them had the ability to remove or amend the defamatory material from the "publication." It remains to be seen whether wikis will be regarded as more akin to an [[internet service provider]], which is generally not held liable due to its lack of control over publications' contents, than a publisher.<ref name=Legal/>
| + | |
| − | | + | |
| − | It has been recommended that trademark owners monitor what information is presented about their trademarks on wikis, since courts may use such content as evidence pertaining to public perceptions. Joshua Jarvis notes, "Once misinformation is identified, the trade mark owner can simply edit the entry."<ref>{{citation|work=Managing Intellectual Property| last = Jarvis | first = Joshua|title=Police your marks in a wiki world|url=http://heinonline.org/HOL/LandingPage?collection=journals&handle=hein.journals/manintpr179&div=31&id=&page=|pages=101–103|date=May 2008|issue=179}}</ref>

Wiki一词来源于夏威夷语的“wee kee wee kee”, 发音wiki, 原本是“快点快点”的意思，被译为“维基”或“维客”。一种多人协作的写作工具。Wiki站点可以有多人（甚至任何访问者）维护，每个人都可以发表自己的意见，或者对共同的主题进行扩展或者探讨。Wiki也指一种超文本系统。这种超文本系统支持面向社群的协作式写作，同时也包括一组支持这种写作。
WiKi支持面向社群的协作式写作，同时也包括一组支持这种写作的辅助工具。有人认为，Wiki系统属于一种人类知识的网络系统，我们可以在Web的基础上对Wiki文本进行浏览、创建、更改，而且这种创建、更改、及发布的代价远比HTML文本小；与此同时Wiki系统还支持那些面向社群的协作式写作，为协作式写作提供了必要的帮助；最后，Wiki的写作者自然构成了一个社群，Wiki系统为这个社群提供了简单的交流工具。与其它超文本系统相比，Wiki有使用简便且开放的优点，所以Wiki系统可以帮助我们在一个社群内共享某个领域的知识。
由于Wiki的自主性，可增长以及可观察的特点，使Wiki本身也成为一个网络研究的对象。对Wiki的研究也许能够让人们对网络的认识更加深入。
另外因为WiKi是一个群体协作的平台，所以它还有平等、共享的特点。
