Ubiquitous Music Retrieval by Context-Brain Awareness Techniques

Abstract

In recent years, people are used to listening to music because the music can effectively relax our tight life. Hence, how to retrieve the preferred music from a large amount of music data has been an attractive topic for many years. Traditionally, music retrieval contains two main types, namely text-based music retrieval and content-based music retrieval. However, these traditional music retrieval types ignore a human sense: emotion. That is, the preferred music might be different in different emotions. In fact, the emotion is highly related to the environment and it can be represented by brain actions. Therefore, in this paper, we propose a creative approach that performs a ubiquitous music search by content comparisons of brains and music. The major intent of this paper is to provide affective music retrieval in different contexts. Without any query, the context-brain triggers the music search and the context-related music will be retrieved by computing brain similarities and music similarities. The proposed approach was materialized and evaluated by a number of volunteers. The evaluation results reveal that, the proposed affective music retrieval can obtain high satisfactions for the invited testing users.
