Abstract

The invention provides a label identification method and device, and relates to the technical field of big data. The method comprises the following steps: extracting a multi-modal feature of a to-be-identified video, and determining a first label of the to-be-identified video by using the multi-modal feature; classifying and identifying the to-be-identified video to obtain a category of the to-be-identified video, and identifying a second label of the to-be-identified video based on the category of the to-be-identified video; and obtaining a third label of the to-be-identified video through a new hot label set updated in real time, and determining a video label of the to-be-identified video in combination with the first label, the second label and the third label. According to the technical scheme provided by the invention, the accuracy of label identification can be improved.

Description

technical field [0001] The present application relates to the field of big data technology, in particular, to a tag identification method and device. Background technique [0002] Video tags play a very important role in services such as video recommendation and video search. Video tags can not only accurately describe the characteristics of videos, but also assist in describing users' interests and habits, and can provide comprehensive and accurate basis for services such as video recommendation and video search. [0003] In related technologies, the video label is mainly predicted by training a model. However, this solution usually only achieves a good recognition effect on general and abstract tags, but cannot recognize refined and specific tags, and it is difficult to meet the actual needs of video tags. [0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of th...
