Abstract
In one embodiment, a method includes receiving a query from a user for videos; identifying videos matching the query; retrieving, for each identified video, a set of keyframes that are associated with one or more concepts; calculating, for each keyframe of each identified video, a keyframe-score based on a prevalence of the concepts associated with the keyframe, determined with reference to the concepts associated with each other keyframe in the set of retrieved keyframes for the identified video; and sending, to the first user, a search-results interface including search results corresponding to one or more of the identified videos, each search result comprising keyframes for the corresponding identified video having keyframe-scores greater than a threshold keyframe-score.
