Abstract:

Article Preview

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.
