Problems solved by technology
It can be seen that the duration of entering the video system has a greater impact on the number of clicks and impressions of video A itself
Therefore, the click-through rate determined by the number of clicks of the video itself and the number of impressions will be used as the basis for the quality evaluation of video A, which will lead to inaccurate quality evaluation
At the same time, for videos that have just entered the video system, there are no clicks and impressions, which will make it impossible to evaluate the quality of the video

The invention provides a video quality evaluation method and apparatus, and belongs to the technical field of video processing. According to the video quality evaluation method and apparatus provided by the invention, when a click rate is determined, the click rate of a video is determined by a smoothing parameter of the video. The smoothing parameter is determined according to a click frequency and a display frequency of each video in a category to which the video belongs, that is, the smoothing parameter is determined according to behaviors that similar videos of the video are clicked and displayed by a user. Since the behaviors that the similar videos are clicked and displayed by the user have a similarity, the smoothing parameter can take a correction function to the click frequency and the display frequency of the video, and the video click rate determined according to the smoothing parameter can be closer to a reality; and when quality evaluation is performed on the video with the click rate as a basis, the quality of the video can be evaluated more accurately.
Description
technical field [0001] The invention belongs to the technical field of video processing, and in particular relates to a video quality evaluation method and device. Background technique [0002] When searching for videos by keywords, videos associated with the search keywords are usually displayed to the user in a certain order. In order to sort video search results more reasonably, it is necessary to rank high-quality videos that are highly relevant to search terms at a higher position. Therefore, how to evaluate the video quality has become a widely concerned issue. [0003] In the prior art, the number of clicks and the number of impressions of the video itself are usually used to determine the click-through rate, and the quality of the video is evaluated according to the click-through rate. [0004] In the process of realizing the present invention, the inventors have found that there are at least the following problems in the prior art: [0005] The number of clicks a...
