Realization of sound-scape agent by the fusion of conceptual fuzzy sets and ontology

We propose a method for representing common concepts by fusing conceptual fuzzy sets (CFS) with ontology. We also describe a method of conceptual matching for retrieving information that meets a user's intentions. The matching is done based on the region of the ontological structure covered by the CFS representing the user's intention as well as on the original keywords. We apply the proposed conceptual-matching method to an agent, which selects music matching the tone of a text composition. Selection of music for two e-mail notes shows that the proposed system can select music that matches human feelings.
