Abstract

The invention discloses a user experience model training method and a short video user experience evaluation method and device. The user experience model training method comprises the steps of obtaining short video data of short video tasks historically watched by accounts; for each account, dividing a short video task historically watched by the account into one or more video processing units, wherein each video processing unit comprises a plurality of short video tasks continuously watched; acquiring video feature data of each video processing unit according to the short video data; and training a user experience model according to the video feature data of each video processing unit. The features aggregated on the dimension of the video processing unit can reduce the influence of mutual independence between short video tasks and better describe the behavior change of the user in a long time range, so that the QoE fitting level is improved, and the effectiveness of the model is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of live broadcast technology, and in particular to a user experience model training method, a short video user experience evaluation method and device. Background technique [0002] In recent years, with the development of network transmission technology and audio and video technology, the streaming media industry has ushered in a rapid explosion. While providing efficient and reliable services, video service providers are also paying more and more attention to research, understanding, and improving user experience (QoE). By collecting a large amount of user behavior, video content, network transmission, equipment environment and other related data generated during the use of video services by users, video service providers can mine the relationship between video and user viewing satisfaction, guide the optimization of audio and video transmission, Algorithms such as content distribution an...
