Embodiment Construction

[0029] The invention discloses a user implicit scoring method based on the relative duration and viewing time of the user watching the video, and adjusts the user's scoring of the video according to the length of the video and the proportion of the user watching the video, which more reasonably reflects the user's interest in the video Adjusting the label weight through time degradation can be closer to the user's interest change trend.

[0030] Other characteristics, objects and advantages of the present invention will become more apparent by reading the detailed description of non-limiting embodiments made with reference to the following drawings:

Abstract

The invention provides a user implicit rating method for recommending a video, which is characterized by comprising the following steps of: a, receiving operation information which is executed on a video to be rated by a user; b, calculating a primary score based on video duration and a user observation proportion; and c, carrying out further calculation on the primary score according to a degeneration time difference to obtain a final score, wherein the degeneration time difference is a difference of time for carrying out operation on a video by a user and carrying out implicit rating on the video. The method disclosed by the invention is a method for adjusting user implicit rating by combing time degeneration according to the video duration; and the method has the advantages of more accurately grasping interests of the user, being more close to a user interesting changing tendency and being more efficient and portable.

Description

technical field [0001] The invention relates to the field of user scoring methods for video recommendation, in particular to an implicit scoring method for users based on the relative duration and viewing time of videos watched by users. Background technique [0002] In various recommendation systems, users' ratings on resources are an important indicator to determine the user's interest. However, only a small number of users are willing to actively rate resources, so computing implicit user ratings is a method adopted by many recommendation systems. [0003] In video recommendation systems, there are mostly two traditional implicit scoring methods. One adopts a 0-1 system, 0 means that the user has not watched the resource, and 1 means that the user has watched the resource. Even if a user has viewed the resource, it doesn't necessarily mean that the user is interested in it, so this approach doesn't make much sense. Another method is to score the resource according to t...
