- Abstract
- A music search apparatus using an emotion model includes a music database (DB) for storing sound source data about a plurality of pieces of music and Arousal-Valence (AV) coefficients of the respective pieces of music. An emotion model generation unit classifies different emotion types into a plurality of groups, and generates an emotion classification model from using respective probability distributions of the plurality of groups for an AV coefficient plane. A music search unit identifies an emotion type from using information entered by a user when a music search request is received, detects an AV coefficient range for designating an AV coefficient corresponding to the identified emotion type from using the emotion classification model, and searches the music DB for music corresponding to the AV coefficient range.
