A Collaborative Filtering Recommendation Algorithm with Time Adjusting Based on Attribute Center of Gravity Model
In the collaborative filtering recommendation technology, the similarity measurement part plays a vital role,and similarity measurement accuracy seriously affects the similarity measurement part and all the subsequent parts.However, there are many shortcomings in the similarity measurement part of traditional memory-based collaborative filtering recommendation technology, in order to solve the inaccuracy under special circumstances, this paper proposes an improved algorithm, a collaborative filtering recommendation algorithm with time adjusting based on attribute center of gravity model, through altering the process of similarity calculation.Simulation results show that the improved algorithm gains a higher recommendation accuracy, compared with the traditional algorithms.
