The English-language Wikipedia will test a new policy of checking user contributions to certain high-profile entries before publishing them.
If approved permanently, this policy would be at odds with Wikipedia's "laissez-faire" approach towards fact-checking that, while controversial, is nonetheless key to its massive popularity.
Wikipedia lets anyone instantly publish changes to most of its encyclopedia entries, except for some articles that are subject to constant malicious edits. Depending on the case, Wikipedia places different limits on who can edit these entries and to what extent.
Now, the English-language Wikipedia will begin testing a new process that, unlike the existing protection policy, would let anyone edit an entry but places their contributions in a holding queue pending approval from a user Wikipedia considers a "trusted editor" based on the person's participation on the site.
A version of this policy, called Flagged Revisions, is in place at the German-language Wikipedia.
The decision to test Flagged Revisions on the flagship English-language Wikipedia was prompted by changes to the entries of US senators Edward Kennedy and Robert Byrd that incorrectly stated the men had died.
"This nonsense would have been 100 percent prevented by Flagged Revisions," wrote Wikipedia founder Jimmy Wales in his "user talk" page.
A poll of Wikipedia users showed that 60 percent support applying Flagged Revisions to certain entries, according to Wales. Contributions would be held for approval at most for one week, but ideally "a lot less," he wrote, adding that Flagged Revisions will be tried out "for a time-limited test."
Launched in January 2001, Wikipedia, written and edited by volunteer users worldwide, is by far the most popular encyclopedia on the web. It receives about 97 percent of the visits US web surfers make to online encyclopedias, according to web monitoring company Hitwise.
Wikipedia is free and carries no advertising. Its parent organisation, the nonprofit Wikimedia Foundation, recently held a successful fund-raising drive for the $6 million it needed to operate Wikipedia until the end of June.
Wikipedia is often criticized for what critics perceive as a free-for-all attitude towards user contributions, something that has landed it in hot water at times but that is central to its popularity and growth. The site's philosophy is that its community of participants will police itself, correct mistakes, stamp out malicious activity and engage, when necessary, in discussions that lead to consensus over site policies and encyclopedia topics.
The English-language Wikipedia, for example, has over 2.7 million articles, and was, along with other smaller Wikimedia-backed sites, the 10th most popular site in the US, with 58.3 million unique visitors, in December, according to comScore.
The Wikimedia Foundation didn't immediately respond to a request for comment.
