Wikipedia Trust Coloring

From TrustLet, a free, collaborative project for collecting and analyzing information about trust metrics.

Wikipedia Trust Coloring is a demo system in which the text background of Wikipedia articles is colored according to a value of trust, computed from the reputation of the authors who contributed the text, as well as those who edited the text. It is possible to see the demo on a random wikipedia page.

It is based on 2 steps:

• first, compute reputation of all Wikipedia authors at all points in time (algorithms are described in the paper A Content-Driven Reputation System for the Wikipedia).
• second, compute the trust of each word of each article revision, according to the reputation of the original author of the word, as well as to the reputation of any authors that have edited the page.
