Short video keyword extraction method and device and storage medium

Abstract

The invention relates to an artificial intelligence technology, and discloses a short video keyword extraction method. The method comprises the steps of obtaining a short video set, obtaining different frame images of the short video set through regular screenshot, performing preprocessing operation on the different frame images to obtain a target image set and a label set, and performing target detection and attitude tracking on the target image set by using a difference method and an optical flow method to obtain a difference image set and an optical flow image set; training a pre-constructed short video keyword extraction model by using the differential image set, the optical flow image set and the label set to obtain a trained short video keyword extraction model; and receiving a shortvideo, obtaining associated words of the short video by using the trained short video keyword extraction model, and performing keyword extraction on the associated words to obtain keywords of the short video. The invention further provides a short video keyword extraction device and a computer readable storage medium. According to the invention, accurate extraction of the short video keywords isrealized.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a method, device and computer-readable storage medium for extracting associated words from short videos. Background technique [0002] With the rapid development of digital media technology, electronic technology, communication technology and the Internet, data resources have sprung up like mushrooms after rain and have expanded rapidly. Among these massive data resources, short video data is a type of multimedia data with rich semantics, complex structure, rapid development, and huge data volume, and it is also a type of video data with a short length. In the Internet-based video retrieval system, people are accustomed to realize video retrieval with text as associated words through the man-machine interface, and search for the required video data from various sites distributed on the Internet. According to the existing video retrieval system, it is diff...

AI Technical Summary

Problems solved by technology

According to the existing video retrieval system, it is difficult for people to effectively search for the video data they need from the vast amount of video data

The reason is that there is no related word extraction technology based on short videos in the current market
