unfamiliar music and broadening one's interests can enrich the overall music experience. However, since an overwhelming number of music videos are uploaded daily to video sharing services, it is difficult for users to discover music videos from creators or genres they do not usually listen to by relying solely on conventional keyword- or tag-based searches. To address this issue, this study uses time-synchronized comments, which are comments posted in synchronization with specific timestamps in music videos. Specifically, we assume that some of these comments, such as those containing unique expressions about particular scenes, can serve as motivational triggers for users to watch the corresponding music videos. Based on this assumption, we propose an approach that encourages users to explore music videos by using these comments as entry points. To evaluate the effectiveness of the proposed approach, we implemented an experimental system. The system presents multiple time-synchronized comments to the user; when the user selects a comment of interest, they can start watching the music video from a point slightly before the timestamp at which the comment was posted. A user study using this system revealed that the proposed approach enabled users to discover music videos that matched their preferences even in genres they do not usually listen to, and that the comments users found interesting varied across individuals, indicating a diversity of interests.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"388","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"375","bibliographicIssueDates":{"bibliographicIssueDate":"2026-02-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"67"}]},"relation_version_is_last":true,"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20729/0002007013","subitem_identifier_reg_type":"JaLC"}]},"weko_creator_id":"80578"},"id":2007013,"updated":"2026-02-16T00:34:30.289611+00:00","links":{}}
