Problems solved by technology

[0003] When the machine learning method is used to identify the tags corresponding to the video, it is mainly realized based on the text features of the video title. After modeling the text information of the video title and the tags in the massive tag pool of the platform, the correlation is calculated. Then, according to the correlation, the tags corresponding to the video are obtained from the massive tag pool of the platform, resulting in a low accuracy rate of the tag corresponding to the identified video

Abstract

The invention provides a video identification method and device and a storage medium, relates to the technical field of artificial intelligence and computers, and is used for improving the accuracy of identifying video tags. The method includes: inputting the to-be-processed video into the label classification model, and respectively obtaining a matching probability value corresponding to each preset label; inputting the to-be-processed video into a label retrieval model, obtaining candidate labeling labels successfully matched with the to-be-processed video and corresponding target similarities, wherein the target similarity corresponding to each candidate labeling label is determined based on the video data matching similarity between each historical video associated with the candidate labeling label and the to-be-processed video; screening out preset labels with matching probability values reaching a probability threshold value to form a first label set, and screening out candidate labeling labels with target similarity reaching a similarity threshold value to form a second label set; and performing fusion processing on the first label set and the second label set, and determining a target label corresponding to the to-be-processed video. The label recall and accuracy are improved, and the recognition accuracy is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a video recognition method, device and storage medium. Background technique [0002] Video platforms generally need to tag and describe videos. In addition to adding corresponding tags when users upload videos on the video platform, and reviewers of the video platform add corresponding tags to each video during the review process, machine learning can also be used. The method identifies the tag corresponding to the video. [0003] When the machine learning method is used to identify the tags corresponding to the video, it is mainly realized based on the text features of the video title. After modeling the text information of the video title and the tags in the massive tag pool of the platform, the correlation is calculated. Furthermore, according to the correlation, the tags corresponding to the videos are obtained from the massive tag pool of the platform, resulting i...
