Abstract

The invention discloses a social relationship-aware IPTV user behavior modeling and program recommendation method. The main tasks include: (1) Based on historical viewing logs, analyze the behavior of IPTV users, and combine the user group clustering results to construct user and The viewing preference model of the group to which the user belongs; (2) Utilize the dense program category similarity coefficient matrix to avoid the adverse effects of data sparsity on recommendation, improve the tensor decomposition model, and optimize the recommendation results; (3) Comprehensively consider IPTV users and the viewing preferences of the groups to which they belong to realize personalized IPTV program recommendations for users. Compared with existing recommendation algorithms, the method proposed by the present invention has significant improvements in recommendation accuracy, recall rate, etc.
