Abstract

The invention provides a method and a device for determining a cover video frame, wherein, the method comprises the following steps: extracting keywords of an article text, and obtaining a first vector corresponding to each keyword; extracting a subject word of each video frame in a preset period of time in the article video, and obtaining a second vector corresponding to each subject word; calculating a similarity between each video frame and the text of the article according to a second vector corresponding to each subject word and a first vector corresponding to each keyword; determining the target video frame to be a cover video frame according to the similarity between each video frame and the text of the article. As a result, the effect that the video frame as the cover corresponds to the consistent picture and text of the article content is realized, the video frame as the cover is automatically adapted to the article content, and the cover determination efficiency and the click-through rate and browsing experience of the user are improved.

Description

technical field [0001] The invention relates to the technical field of multimedia information, in particular to a method and device for determining a cover video frame. Background technique [0002] With the vigorous development of the mobile Internet, more and more videos appear in articles. For example, in the push articles of social networking sites, many funny video clips are often included in order to improve the interest of the article, in order to let users better understand Video content, the video inserted into the article is displayed in the form of a video cover.
