TrustRank
The Trust Rank - algorithm is a method for evaluating the quality of websites . It was developed by Zoltán Gyöngyi, Héctor García-Molina and Jan Pedersen and a patent has been applied for by Yahoo . It is used for the semi-automatic classification of the quality of a page or to find spam pages and is intended to help search engines evaluate websites.
The algorithm
The approach of TrustRank method is that Web pages operated by trusted sites ( trust for trust Engl.) To link themselves are trustworthy, while spam sites are rarely or never link to from trusted sites.
With the TrustRank algorithm, a small number of trusted sites are selected manually. Similar to the PageRank procedure, they can then pass on trust to linked websites. A site's trustworthiness decreases the further away it is from the sources. The TrustRank is calculated automatically using the link structure after the sources have been specified manually, i.e. H. the links on the websites.
Other uses of the term
The term TrustRank is used not only for the Gyöngyi, García-Molina and Pedersen algorithm, but also for a number of other methods. An antiphishing filter from Google also bears this name.
