Algorithm of User Interest Drift Based on Matrix Representation

Abstract:

In order to improve the efficiency of user interest drift, proposed an algorithm of user interest drift based on matrix representation. Time Window was brought in to group short-time interest; Semantic Net was used to combine user interest categories; interest weight was replaced by interest rate to show the preference of user interest; considering the sustainability and volatility of interest to calculate the ultimate interest model. Experiment indicated, compared with previous method, this algorithm improved the accuracy of dealing with interest shift.
