In this paper, we propose an auto-indexing method in retrieval based on contens of digital information of musical performances such as MIDI. To this end, we first extract phrases, which are assumed as a unit for indexing, from automatically segmenting melodies into \"Sub-melodies\". In the proposed method of automatic segmentation into phrases, DP matching is employed, exploiting repeated occurrences of similar phrases in a song. The effectiveness of our method was evaluated through an experiment using MIDI data.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"124","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告データベースシステム（DBS）"}],"bibliographicPageStart":"117","bibliographicIssueDates":{"bibliographicIssueDate":"1998-07-08","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"57(1998-DBS-116)","bibliographicVolumeNumber":"1998"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T22:52:14.559176+00:00","updated":"2025-01-22T21:59:18.630332+00:00"}
