Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0052] After a period of operation, a video website will accumulate a lot of user viewing data, such as playback data, drag and drop data, barrage data, etc. The video website can use these data to fit a curve, and analyze the curve to get the video's popularity. trend of change. Specifically, the video website can analyze the upward trend of the curve and the reasons for the peak, as well as the reasons for the decline and trough of the curve, and then make targeted decisions. It can be seen from the above that in order to make accurate and effective directional promotion, the calculation of the trend of the curve must be accurate, otherwise the suggestions provided will be invalid, and then how to evaluate the calculated curve, how to accurately calculate the accuracy of the...

Abstract

The embodiment of the invention provides a determination method and device of a video assessment set, and electronic equipment. The method comprises the following steps: acquiring a video clip interception record for a to-be-assessed video by a video platform user, wherein the video clip interception record comprises starting time and ending time of each intercepted video clip; computing the interception frequency that each unit clip at different time quantum in the to-be-assessed video is intercepted according to the starting time and the ending time of each intercepted video clip of the video clip interception record; selecting the unit clip with the interception frequency not less than a preset threshold to obtain each to-be-aggregated unit clip; aggregating various to-be-aggregated unit clips in time order according to a preset clustering algorithm, thereby obtaining various target video sequences; and determining a set formed by various target video sequences as an assessment setof the to-be-assessed video. Through the determination method provided by the embodiment of the invention, the assessment set of the video is efficiently obtained.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device and electronic equipment for determining a video evaluation set. Background technique [0002] The video website will do various analysis on the online video, analyze whether the online video is liked by the audience, and analyze the part of the video that is liked by the audience, so as to do targeted promotion and operation, etc., to improve the user experience of the video website. [0003] To perform analysis on videos, an evaluation set of videos needs to be determined. In the prior art, when determining the evaluation set of a video, annotators are required to score the video frames after watching the video manually, and use these scored video frames as the evaluation set of each video. However, this method requires the annotator to watch the entire video first, to have an overall understanding of the entire video, and then re-watch the video and...
