Recently, an online video sharing service in which users can provide comments for temporal events occurring in video clips not for entire clips has gained a lot of popularity. We focus on musical audio signals included in video clips of music performances and propose a probabilistic model that jointly generates acoustic features and comment features. The model can be trained by using many music clips and their corresponding comments. Given a new clip as input, the system then determines appropriate temporal positions of comments and estimates their content and length. Finally, comment sentences are generated by taking word concatenations into account as language constraints. Our experimental results showed that comment accuracy was improved when the system used not only acoustic features of an input clip but also users' comments in the clip.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2009-07-22","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"20","bibliographicVolumeNumber":"2009-MUS-81"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:24:33.183687+00:00","updated":"2025-01-22T02:32:34.157115+00:00"}
