The invention discloses a method and device for obtaining a video cover, computer equipment and a readable storage medium, and belongs to the technical field of artificial intelligence. The method comprises the following steps: acquiring a text and a video corresponding to the text, and extracting at least one keyword feature vector corresponding to at least one keyword included in the text and a plurality of video clip feature vectors corresponding to a plurality of video clips included in the video through feature vectors; inputting the at least one keyword feature vector and the multiple video clip feature vectors into a first model, obtaining one or two matrixes output by the first model, wherein one element in any matrix is used for indicating the correlation degree between one target inquiry mark and one main key mark; and determining an alternative video clip related to the at least one keyword from the plurality of video clips based on each element in one or two matrixes output by the first model, and determining a video cover of the video based on the alternative video clip. The success rate of obtaining the video cover is high.
Description
technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular to a method, device, computer equipment and readable storage medium for obtaining a video cover. Background technique [0002] On the video display page, a video cover is often set for the video, and the set video cover is, for example, a video segment intercepted from the video. In the case that the user provides text, if a video clip relatively related to the text can be set as a video cover, it is beneficial to improve user experience. [0003] In related technologies, image understanding algorithms are used to predict semantic tags for each video segment in a video, so as to obtain the semantic tag corresponding to each video segment. If the text provided by the user contains a semantic tag, the video clip corresponding to the semantic tag in the video is used as the video cover. [0004] However, the coverage of predicted semantic tags in related...
