Abstract

The invention discloses a multi-source multi-view-angle transductive learning-based short video automatic tagging method. The method comprises the steps of obtaining short video data; preprocessing the short video data to generate image key frames consistent in format, audio tracks, texts and semantic tags; extracting multi-view-angle eigenvectors of the image key frames, the audio tracks and the texts; establishing a short video tagging database, wherein the multi-view-angle eigenvectors and the semantic tags are stored in the short video tagging database; calculating the similarity between the multi-view-angle eigenvectors; establishing a multi-view-angle fusion space through the similarity between the multi-view-angle eigenvectors; and transductively solving the multi-view-angle fusion space, and automatically tagging the semantic tags to the to-be-tagged short video data. The invention furthermore discloses a multi-source multi-view-angle transductive learning-based short video automatic tagging system. According to the method and the system, multi-source information attached to the short video data is fully considered, so that the tagging accuracy is improved.

Description

technical field [0001] The invention relates to the field of short video tagging, in particular to a short video automatic tagging method and system based on multi-source and multi-view direct push learning. Background technique [0002] With the development of mobile communication technology and Internet technology and the popularization of various smart terminals, short videos shot through mobile phones, tablet computers and other terminals and shared in social circles have become popular social applications among users. This short video social method originated from the video sharing website Vine in 2013. Its mobile client can limit the shooting time of short videos to 6 seconds. Various short video applications, such as Instagram, Meipai, WeChat, Weibo, Tencent Weishi, Weikepai, etc., have developed rapidly in recent years, and the duration of short videos has also expanded to 60 seconds. Short videos are seamlessly connected to various social platforms on the Internet,...
