Wikitrust is a software product That assesses The Credibility of happy and author reputation of wiki items using an automated algorithm . WikiTrust is a plug-in for servers using MediaWiki platform, such as Wikipedia . When installed on MediaWiki website it is designed to enable users 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 University of California, Santa Cruz , California , in response to Wikipedia: Meta quality sponsored by the Wikimedia Foundation .  The project, discussed at Wikimedia 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. 
WikiTrust computes, for each word, three pieces of information:
- The author of the word.
- The revision where the word (and the immediate surrounding text) was inserted. By clicking on a word, visitors are sent to the revision where the word originated.
- The “trust” of the word, indicated by the word background coloring (orange for “untrusted” text, white for “trusted” text).
The WikiTrust Considerations of “High Authority.”   This project is still in a beta test stage.  
The criticism has been raised  that “the software does not really measure trustworthiness, and the danger is that people will trust the software to measure something that it does not.” Generally, users whose content is not ” reverted ” by other editors are deemed more trustworthy by the software.  [13 ] References [edit ] References  The software uses a variation of Levenshtein to be able to receive a partial credit for their work. 
The software has also been described as a measure of consensus in an article.  The community of editors collaborate on articles and revise each other until agreement is reached. Users who make edits which are more similar to the final agreement will receive more reputation. The point is also made that consensus revolves around the beliefs of the community, so that the reputation of the community is also reflected.
