摘要：Aiming at the irrationality of existing social recommendation algorithms, such as not fully mining the preference correlation between users and not fully considering the dynamic change of user preferences in time, this paper proposes a dynamic recommendation algorithm based on user long-term and short-term preferences and social influence. From the dynamic change of user preferences and the social relationship of users, the improved gating cycle unit is used to model the user rating information and extract the long-term and short-term preference features; According to the user correlation matrix, the social impact of learning target users is expressed. Experiments on two real datasets show that the proposed algorithm is better than the comparison algorithm.
