Embodiment Construction

[0021] Such as figure 1 As shown, a video program recommendation method based on data fusion includes the following steps:

[0022] 1) The user behavior data collection step, collects the browsing behavior data of the user on the video website, and stores it in the database;

[0023] 2) The data fusion step is to convert the browsing behavior data of a certain user to a certain video program into the user's interest degree value to a certain video program;

[0024] 3) Program recommendation step, according to the user's interest degree value to certain programs, recommend other users with the same preference to other programs with high interest degree value of the user;

[0025] Wherein, the browsing behavior data includes playing behavior data, and the duration ratio r is obtained by dividing the duration of the user playing the program by the length of the program, and the larger the duration ratio r, the higher the interest degree value.

[0026] Wherein, the time length ...

Abstract

A data fusion based video program recommendation method comprises the following steps: 1) collection of behavioral data of users: collecting the behavioral data of the users in browsing video websites and storing the behavioral data in a database; 2) data fusion: converting the behavioral data of a user in browsing a video program into the interest value of the user in the video program; and 3) program recommendation: according to the interest value of the user in a few programs, recommending the programs in which the user has high interest value to other users having the same favorites, wherein the behavioral data in browsing comprise behavioral data in playing. The duration ratio r is obtained by dividing the duration of the programs played by the users by the total duration of the programs. The higher the duration ratio r is, the higher the interest value is. As long as the users play the programs and other behavioral data of the users related to the interest value are fused, the program lists to be recommended can be generated more accurately and the degree of satisfaction of the users with the recommended programs is greatly improved.

Description

technical field [0001] The invention relates to a method for recommending video programs. Background technique [0002] With the development of the video network, watching video programs through the network has become one of the purposes of surfing the Internet for many network users.
