When exploiting archived news videos as information sources, it is important to track the flow of topics to understand their contents comprehensively. Concerning it, a method that structures the chronological semantic relations between news stories; the \"topic thread structure\" has been proposed. It allows the understanding of the circumstance of topics by tracking related stories one after another from the initial story. However, this imposes a user to watch many stories along the structure when it contains various topics. Thus, we propose a method that estimates the representative story transition in a topic thread structure. In the proposed method, features obtained from a story and those from the topic thread structure are used for the estimation. We confirmed the effectiveness of the proposed method by comparing it with a representative topic thread obtained from votes by subjects.", "subitem_description_language": "en",
