Intelligent mobile content-based retrieval from digital music libraries

Abstract

In this paper, we present and evaluate a middleware system, called ALIMOS, that we have developed fully. Our system facilitates the access to digital music libraries in push technology-based mobile services. Specifically, our system provides a semi-automatic interface that allows mobile users to interact with a digital music library and find/retrieve music files in a flexible way that combines mobile technologies and content-based retrieval techniques. Thus, a mobile user is provided with the ability to query for music files that belong to the same genre by simply sending an example music file from his/her mobile device. Our system was evaluated extensively in a process that followed three stages, namely user background information collection, system performance evaluation, and overall system assessment. The evaluation results are quite positive in terms of both system performance evaluation, and overall system assessment.
