摘要
The diversity of people's musical tastes is one of the significant parts which helps people to better understand the behavior trends and cultural preferences of people. In this paper, based on Hill-type true diversity, we propose an improved diversity metric that fairly captures the diversity of musical tastes. This diversity efficiently considers all the three aspects of diversity definitions: variety, balance, and disparity, and keeps higher discriminatory power. Using this diversity metric, one can analyze users' music tastes on Xiami. com, one of the largest social music media in China; we explore the association between the diversity and various variables which represent users' personal traits, as well as the difference between different genre levels and map the cultural pattern of difference genres. Our findings dig out many efficient factors that deeply impact users' music tastes, and provide the global pattern of musical cultural structure on the Chinese online music society.
