Embodiment Construction

[0091] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0092] The inventors found that, for video distribution platforms (for example, Quick Video, Douyin Short Video APP, Youku Video Network, etc.), the user experience largely depends on the video search hit rate and recommendation accuracy. In order to ensure the search hit rate and recommendation accuracy, it is necessary to accurately classify the massive videos on the platform and assign comprehensive and reasonable tags to each vi...

Abstract

The invention provides a video tagging processing method and device. The method comprises the steps of obtaining original video data; Inputting the original video data into a feature extraction network for image feature extraction to obtain an image feature vector of a first preset dimension of the original video; Performing clustering analysis on the image feature vectors to obtain different classifications of the original video corresponding to the image feature vectors; And for different classifications of the original videos corresponding to the image feature vectors, extracting keywords in titles corresponding to the original videos in the same class, and selecting one or more keywords from the keywords as labels of the original videos of the class according to a first predetermined rule. According to the scheme provided by the embodiment of the invention, efficient and accurate video classification is realized, and high-accuracy and comprehensive video tagging is realized, so that the search hit rate and the recommendation accuracy of the video can be improved.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video tagging processing method, a video tagging processing device, a computer storage medium, and a computing device. Background technique [0002] With the development and popularization of network technology, a large number of aggregated video distribution platforms have emerged, which can provide network users with personalized video services, including uploading, searching, recommending, playing, downloading and other services. In order to make it easier for users to search and use videos, and to recommend videos that meet users' interests and needs, it is necessary to accurately classify the massive videos on the platform and assign comprehensive and reasonable tags to each video. Existing video labeling methods usually use manual labeling, or simply extract keywords from the title and explanatory text of a single video as a label, which has low operation...
