WikiTrust was an extension to MediaWiki and Firefox that implemented an automated algorithm to assess the credibility of content and author reputation. When installed on a MediaWiki website, it enabled users of that website to obtain information about the author, origin, and reliability of that website's wiki text.[1] Stable content, based on an analysis of article history, was displayed in normal black-on-white type, and unstable content was highlighted in varying shades of yellow or orange.
It was undertaken by the Online Collaboration Lab at the University of California, Santa Cruz, in response to a quality initiative sponsored by the Wikimedia Foundation.[1]
WikiTrust was also mentioned on the Wikiquality/Portal site:
What you can do: Try Prof. Luca de Alfaro's trust coloring demo
Luca de Alfaro is an Associate Professor of Computer Engineering at the University of California, Santa Cruz. He is leading a research team to study the patterns in Wikipedia article histories. His team has created a demonstration which colorizes Wikipedia articles according to a value of trust, computed from the reputation of the authors who contributed and edited the text.
The Wikimedia Foundation is supporting Luca's work, and is considering different ways in which it could be usefully integrated into Wikipedia. See Luca's demo site, and send us your thoughts on the wikiquality-l mailing list.
Confusion
[edit]Some of the confusion about whether Wikitrust would be enabled erupted due to an article in Wired.[2] The author of the article, Hadley Leggett filed her story based on a statement from Jay Walsh, Wikimedia's Head of Communications.[3] But according to Erik Möller, the Deputy Director of the Wikimedia Foundation, at the time of her story, the Wikimedia Foundation had no implementation plan or dates, which was contrary to what her story suggested.[4] Erik send an email on Aug 31, 2009 to the WikiEN-l mailing list in response to an email from Brion Vibber[4]. Erik clarified by saying the following:
“ | Any integration is contingent on the readiness of the [WikiTrust] technology. It seems to have matured over the last couple of years, and we're planning to meet with Luca soon to review the current state of things. There's no fixed deployment roadmap yet, and the deployment of FlaggedRevs is our #1 priority. | ” |

Luca de Alfaro is an associate professor at UC Santa Cruz, USA. He is developing WikiTrust, a reputation system for wiki authors, and a trust system for wiki text. Authors gain reputation when their contributions prove long-lived, and text trust is an indication of the extent with which it has been revised. The code, available under BSD license, also contains utilities such as fast block text comparison, and more.

WikiTrust may be added to Wikipedia Wired reports that the WikiTrust MediaWiki extension for evaluating the trustworthiness of text within Wikipedia articles may be deployed on English Wikipedia over the next few months. Researchers at the University of California, Santa Cruz, led by Luca de Alfaro, have been developing the WikiTrust software since 2007; they created a WikiTrust demonstration in late 2007 (no longer available) based on a dump of English Wikipedia. The extension works by determining the origin of each segment of text within an article and calculating a trust value based on the reputation of the editor who added it and the reputations of editors who subsequently edited the article without removing the text. Authors' reputations are based on how much stable content they have added and how rarely their contributions are reverted. The extension is deployed on the WikiTrust wiki; the trust features are accessible through the "check text" tab. The WikiTrust team has also developed an experimental Firefox add-on that adds a trust tab at the top of article pages. On a mailing list discussion, Brion Vibber confirmed that plans to eventually deploy WikiTrust are in the works:

WikiTrust Just came across this article in InfomationWeek:
Note: Same entry as in Wikipedia:Press coverage 2009. Doesn't seem to be covered here in en:Wiki, but see this search in Meta. — Becksguy (talk) 23:49, 31 August 2009 (UTC)
I have yet to find an article on en.wiki that this works on. Anyone know what the deal is? 90.197.107.184 (talk) 05:12, 1 September 2009 (UTC)
