Abstract

The embodiment of the invention discloses a video analysis method and device, equipment and a storage medium. The method comprises the steps of obtaining bullet screen information sent when audience users watch videos; Identifying an emotion tag to which each piece of bullet screen information belongs; Determining the proportion of the bullet screen information belonging to each emotion tag; Calculating a quality evaluation value of the audience user to the video according to the proportion; The problem of inaccurate evaluation and one-sided evaluation caused by evaluation of the video qualityonly through bullet screen information is solved, so that the quality of the video content is further analyzed according to the emotion of audience users on the video, the analysis accuracy of the video content is improved, and the video generating emotion resonance with the audience users can be found indirectly.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data processing, and in particular, to a video analysis method, device, device, and storage medium. Background technique [0002] In the live broadcast environment, the interaction between the audience user and the anchor user is mainly that the anchor user interacts with the audience user in the form of voice, and the barrage is the only way for the audience user to communicate with the anchor user. Generally, the number of bullet chats is used to evaluate the live broadcast content of anchor users, but only quantitative analysis is not enough to indicate the quality of live broadcast content. Contents of the invention [0003] The present invention provides a video analysis method, device, equipment and storage medium, so as to analyze the quality of video content according to the emotions of audience users on the video, thereby improving the analysis accuracy of video content, w...
