There are two prominent recommendation methods -collaborative filtering and content-based recommendation, which have respective problems. The former cannot recommend newly-released musical pieces that have no ratings because recommendations are based on actual user ratings. Furthermore, artist variety in recommended pieces tends to be poor. The latter has unreliability in modeling of user preferences;the content similarity does not completely reflect the preferences. Our method integrates both rating and content data by using a Bayesian network called an aspect model. In this model, unobservable user preferences are directly represented by introducing latent variables, which are statistically estimated. To verify our method, we conducted experiments by using actual audio signals of Japanese songs and the corresponding rating data collected from Amazon.co.jp. The results showed that our method solves the above-mentioned problems and outperforms the two conventional methods in terms of recommendation accuracy and artist variety.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"52","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"45","bibliographicIssueDates":{"bibliographicIssueDate":"2006-08-07","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"90(2006-MUS-066)","bibliographicVolumeNumber":"2006"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"updated":"2025-01-22T05:15:17.170168+00:00","links":{}}
