A new user interest shift modelling algorithm for websites with hierarchical classification structure
Zhang Jian-bin · Systems Engineering - Theory & Practice · 2008
To identify Web users' interest shift on hierarchical structure websites,this paper present a new algorithm,which is used for adaptive website building and composed of two models based on exponential decay and Bayesian posterior probability respectively.Experiments based on a real Internet website show that the proposed algorithm can identify the user interests' shift promptly,as well as satisfying personalized information demands.The proposed algorithm can thus be widely implemented on various websites such as online News and virtual communities.
