抄録

In this paper, we propose the system of extracting feature of scenes in a lecture video. To avoid a hand work on a lecture video, we propose a new method automate the judgment of importance of a scene. This system uses the TF-IDF method that is the technique of the natural language processing. Our system has four functions to watch a lecture video efficiently. They are the function of extracting feature of scenes, character string choice, keyword search and important scene choice.These functions help to watch a lecture video efficiently.
