| Research Abstract |
This research aims to develop techniques that can accurately recommend musical pieces to users at a low computational cost and enable users to actively control recommendation results through human-machine interaction. First, we have studied on automatic recognition of musical contents, which could be used for making recommendations. Consequently, we successfully developed a method that can accurately detect multiple fundamental frequencies from polyphonic musical audio signals, and significantly improved the accuracy of recommendations. Second, we have been working on development of social-network functions that enable users to selectively focus on musical contents in making recommendations and to discover other users who have the similar tastes. We implemented and examined a Web-based recommender system. Future work includes improvement of social networks and practical operations of the recommender system.
