Analysis method of association between mood of music and folksonomy tag

摘要

According to the present invention, a method for analyzing relation between the mood of music and a folksonomy tag includes: a step of collecting an AV value representing the mood of music and a folksonomy tag of the music; a step of learning support vector regression (SVR) using the collected AV data of the music and generating an AV prediction and determination model; a step of predicting an AV value of new music using the generated AV prediction and determination model; a step of defining the predicted AV value of the music as a representative AV value of the music; a step of generating a mapping table defining relations between the folksonomy tag of the new music and the AV value of the music; and a step of analyzing the generated mapping table. According to the present invention, in make use of the mood intensity (intensities of arousal and valence) of music as an internal tag of the music, by suggesting a mapping table defining relations between the AV value and the folksonomy tag of music and analyzing correlations between the tag and the AV value, distribution difference in the AV value is generated.
