EMIF: Towards a Scalable and Effective Indexing Framework for Large Scale Music Retrieval

In this article, we present a novel indexing technique called EMIF (Effective Music Indexing Framework) to facilitate scalable and accurate content based music retrieval. It is designed based on a "classification-and-indexing" principle and consists of two main functionality layers: 1) a novel semantic-sensitive classification to identify input music's category and 2) multiple indexing structures - one local indexing structure corresponds to one semantic category. EMIF's layered architecture not only enables superior search accuracy but also reduces query response time significantly. To evaluate the system, a set of comprehensive experimental studies have been carried out using large test collection and EMIF demonstrates promising performance over state-of-the-art approaches.
