Abstract

The invention relates to a time-aware video-on-demand recommendation method for TV boxes. According to the invention, based on a weight regression matrix decomposition model, the characteristics of time perception are introduced as auxiliary information to generate a recommendation list with time-varying attributes for time slots with similar playback modes. The invention aims at the on-demand video of the network television box, and the video recommendation effect can be remarkably improved after the invention is used; In addition, the invention can maintain better recommendation accuracy compared with the comparison algorithm during the cold start period of the video. In summary, the invention can bring more accurate and personalized recommendation service for the user of the TV box using the on-demand service.

Description

technical field [0001] The invention belongs to the field of recommendation systems and multimedia applications, and in particular relates to a novel method for recommending video on demand for TV boxes based on time perception. Background technique [0002] The emergence and development of the Internet has brought a lot of information to ordinary users, and at the same time it will bring about the problem of information overload. The introduction of a recommendation system is a common method to solve the problem of information overload. The recommendation system can calculate the user's personal preference and recommend personalized items to the user based on the user's personal information, item metadata, and interaction information between the user and the item. [0003] Compared with search engines, recommendation systems can actively provide users with personalized candidate items, instead of requiring users to initiate requests like search engines. In this mode, recomm...
