摘要:
An audio information retrieval method, medium, and system that can rapidly retrieve audio information, even in noisy environments, by extracting a modulation spectrum that is robust against noise, converting features of the extracted modulation spectrum into hash bits, and using a hash table. The audio information retrieval method may include extracting a modulation spectrum from audio data of a compressed domain, converting the extracted modulation spectrum into fingerprint bits, arranging the fingerprint bits in a form of a hash table, converting a received query into an address by a hash function corresponding to the query, and retrieving the audio information by referring to the hash table.

A personalized service method using a user history in a mobile terminal is provided. The personalized service method using the user history in the mobile terminal includes: checking at least one of event information and context information which occurred due to a user; checking a user's location, a user's condition, a user's emotional state, or an event occurrence time when the at least one of event information and context information occur; reflecting the user's location, the user's condition, the user's emotional state, or the event occurrence time in the at least one of event information and context information, and recording the at least one of event information and context information, having reflected the user's location, the user's condition, the user's emotional state, or the event occurrence time, in a database in a diary type; and displaying a representing image corresponding to the at least one of event information and context information, having been recorded in the diary type.

A method and apparatus for classifying mood of music at high speed. The method includes: extracting a Modified Discrete Cosine Transformation-based timbre feature from a compressed domain of a music file; extracting a Modified Discrete Cosine Transformation-based tempo feature from the compressed domain of the music file; and classifying the mood of the music file based on the extracted timbre feature and the extracted tempo feature.
