In this paper, we describe our Wordy system, which creates a word cloud based on video content and allows users to summarize and search for video content using the word cloud. We focus on lecture videos: converting speech information from the videos into text, extracting keywords from videos through morphological analysis, and creating a word cloud comprised of those keywords. In addition, the keywords in the word cloud are selectable. When a user selects a keyword, the system will find several points of the video in which a teacher talks about the keyword; the system then generates a relevant list of thumbnails. In order to save time for the user, the system offers a digest playback mode that consecutively browses the scenes concerned with the keywords. Herein, we describe our concept and the implementation of the prototype system. |
