Abstract

The invention discloses a video pair mining method and device. The method comprises steps as follows: various video pair sample data containing a video identifier of a requested video, a video identifier of a clicked video and the click rate of the clicked video under the condition that a user watches the requested video are acquired, a probability matrix is determined according to the video identifier of the requested video, the video identifier of the clicked video and the click rate of the clicked video, an N-step transfer matrix corresponding to the probability matrix is calculated, and a video pair is mined according to the calculated N-step transfer matrix and the various acquired video pair sample data. With the method, the potential video pair can be effectively mined, that is, the video pair having the indirect request-click relation can be effectively mined, then the number of video pairs in a video recommendation system is increased, and the recommendation accuracy of the video recommendation system can be further increased.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a video pair mining method and device. Background technique [0002] With the continuous development of network technology, users can obtain more and more things through the network, for example, obtain videos through the network. [0003] At present, in order to provide better services for users, when providing users with the video that the user currently requests from the server (that is, the video that the user currently wants to watch), the video recommendation system in the server will also recommend for the user. The video related to the video currently requested from the server. Subsequently, when the user watches the video currently requested from the server, if there is a video that the user needs in the recommended video, the user will also click on the video. In this application, the The user currently sends a request to the server to obtain the video that...
