Abstract:Traditional collaborative filtering algorithms ignores the change of the user interest,which affects the quality of recommendation in a certain extent.This article introduces time-based data weight,and researches on the collaborative filtering technology based on the change of user interest.Experimental results show that this technology can discover the change of user interest timely,and improve the system recommendation quality.
