Abstract:
　

Song recommendation seeks to actively suggest potential favorite songs to users. This research nowadays becomes a hot research topic due largely to the increasing demand of ubiquitous music access, especially via mobile phone. This talk presents a song recommendation system based on personalized song taste profile which is automatically learned from the song favorite list maintained by each user. To model user taste on song, two types of song attributes must be extracted, i.e. explicit attributes such as singer, composer and lyric writer and implicit attributes such as timber, rhythm, intensity and sentiment. The previous works indicate that audio-based methods are stronge in analysis on timber, rhythm and intensity while weak in sentiment analysis. It is thus proposed in this work to make use of textual information (i.e., song lyric) to detect song sentiment via machine learning approaches. However, problems are encountered when the word-based vector space model is adopted for sentiment analysis. The sentiment-based vector space model is therefore proposed in this talk to deal with the problems. Preliminary experiments show the new solution is very promising.
