This research leads to the development of a system that generates minutes by using repeated structuring of discussion and summarizing between a user and the system. To realize the system, we propose a novel tree structure dedicated to representing the discussion structure of a meeting based on the relative importance of utterances underlain by the semantic structure of meeting records, by using verbal and non-verbal information. The system aims to grasp the point of the meeting efficiently by interactively manipulating this tree structure and giving different viewpoints to each system user. In the evaluation on important utterance extraction using the proposed system, it was shown that the score of ROUGE-2 was higher than that of the existing document digest technique. Moreover, in the evaluation by subjects conducted by 10 subjects, it was shown that the system can grasp conference contents efficiently, and the usefulness of the system.
