What is "wikitrust"

WikiTrust is a software product that assesses the credibility of content and author reputation of wiki articles using an automated algorithm. WikiTrust is a plug-in for servers using the MediaWiki platform, such as Wikipedia. When installed on a MediaWiki website it is designed to enable users of that website to obtain information about the author, origin, and reliability of that website's wiki text. Content that is stable, based on an analysis of article history, should be displayed in normal black-on-white type, and content that is not stable is highlighted in varying shades of yellow or orange.

WikiTrust on Wikipedia was a project undertaken by the Online Collaboration Lab at the University of California, Santa Cruz, in response to a Wikipedia:Meta quality initiative sponsored by the Wikimedia Foundation. The project, discussed at Wikimania 2009, was one of a number of quality/rating tools for Wikipedia content that the Wikimedia Foundation was considering. Communications of the ACM (August 2011) had an article on it. WikiTrust is designed for English and German use via the Wiki-Watch pagedetails for Wikipedia articles, in several languages via a Firefox plugin or it can be installed in any MediaWiki configuration. As of 2012, WikiTrust appears to be an inactive project.
