          <datacite:description descriptionType="Other">音楽データベースの大規模化が進む中、従来の書誌情報からによる検索以外に、演奏内容からの検索への要求が高まっている。本稿では、音楽演奏情報の内容からの検索において、インデクシングを自動で行う手法を提案する。提案手法では、楽曲の主旋律（メロディ）を自動的に分割して得られるフレーズをインデクシングの単位する。フレーズへの自動分割においては、楽曲中に類似したフレーズが繰り返し現れるという特徴を利用し、DPマッチングを用いた手法を提案し、MIDIデータを用いた実験によりその有効性を評価する。</datacite:description>
          <datacite:description descriptionType="Other">As music databases grow, needs to retrieval capabilities based on contents of musical performances are also increasing in addition to a traditional method based on bibliographical information of songs. 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.</datacite:description>
