Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] The purpose of the embodiments of the present invention is to provide a video recommendation method that collects user data more comprehensively and has higher recommendation accuracy. Thereby, it can be solved that when measuring the interest similarity between users, the algorithm collected in the prior art only extracts from the videos that the users have watched, but cannot extract the user's interest degree information and calculate from the videos that the users have not watched. its effect on dependency. Because if two users don’t like a certain video, there are hidden similarities bet...

Abstract

The invention applies to the field of video recommending and provides a social network video recommending method and device. The method includes: acquiring positive sample data of users and negative sample data of the users, and calculating interest similarity value of the users according to the positive sample data and the negative sample data; calculating familiarity value of the users according to friend quantity values of the users; calculating trust levels of the users according to the familiarity value and interest similarity value; calculating credit values of the users according to the trust levels; calculating dependence values of the users according to the trust levels, credit values and interest similarity value, and recommending videos according to the dependence values. The richer user data are acquired herein, facilitating the improvement of recommendation precision.

Description

technical field [0001] The invention belongs to the field of the Internet, and in particular relates to a video recommendation method and device for a social network. Background technique [0002] Social network recommendation refers to the use of social relationships for recommendation. In real life, people must have various relationships with people around them, and the relationship must be based on certain interactions and influences. If the influence factors of other users who interact with the user are fully utilized, the user's preference can be well predicted, which is also a hot research topic in the current recommendation system. [0003] Current social network recommendation data sources generally include social relationship information between users and user behavior information. Wherein, the social relationship information between users mainly includes friend relationship or following relationship. User behavior information includes various types, such as brow...
