Abstract
In an approach to improve video searching embodiments execute heuristic video searching based on importance of semantic features. Embodiments perform hierarchical aggregation of a parsed video into one or more clusters of video excerpts based on a plurality of video features, and display a word cloud to a user to guide feedback. Embodiments traverse the one or more clusters based on a data structure of the hierarchical aggregation and the feedback. Additionally, responsive to reaching selected leaf nodes of the data structure, embodiments generate one or more snapshots of the video excerpts associated with the leaf nodes, wherein the leaf nodes are selected based on the feedback. Further, embodiments display the one or more generated snapshots of the video excerpts to the user.
