[Phpwiki-talk] A ContentDriven Reputation System for the Wikipedia

[Reini U. <ru...@x-...>]

"Researchers at UCSC developed a tool that measures the trustworthiness 
of each Wikipedia page.[1] Roughly speaking, the algorithm analyzes the 
entire 7-year user-editing-history and utilizes the longevity of the 
content to learn which contributors are the most reliable: If your 
contribution lasts, you gain 'reputation,' whereas if it's edited out, 
your reputation falls. The trustworthiness of a newly inserted text is a 
function of the reputation of all its authors, a heuristic that turned 
out to be successful in identifying poor content. The interested reader 
can take a look at this demonstration[2] (random page with white/orange 
background marking trusted/untrusted text, respectively; note "random 
page" link at the left for more demo pages), this  presentation 
(pdf)[3], and this paper (pdf)[4]."
