Abstract

The invention discloses a short video label extraction method and device, a computer device and a storage medium. The method comprises the steps of extracting a prior label of a short video from a label lexicon according to description information of the short video; constructing directed edges between the short videos according to the sequence of watching the short videos by the user; accumulating and normalizing all the in-degree edges between every two short videos to obtain weights of directed edges between the short videos; constructing a priori label vector of the short video through thepriori label of the short video; calculating to obtain a final label vector of each short video through the priori label vector of the short video and the weight of the directed edge between the short videos; and determining a final label of the short video based on the final label vector. According to the method, label extraction is carried out on the relationship between the short videos, so that the label extraction efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of short videos, in particular to a short video label extraction method, device, computer equipment and storage medium. Background technique [0002] Due to the lack of title and description information of short videos, sufficient tag information cannot be extracted from text information. However, since parsing content from video content is not only computationally expensive but also difficult, extracting video tags based on text information is still the mainstream of the industry. practice. [0003] The current short video label extraction methods are mainly through manual marking, text classification, and video content label classification. All these technologies rely on a large amount of manual labeling work, and their extraction methods are inefficient. tags will be outdated and lack new tags, and it is difficult for humans to assign appropriate weights to video tags.
