- We develop a novel content-based query-by-tag music search system for an untagged music database.
We design a new tag query interface that allows users to input multiple tags with multiple levels
of preference (denoted as an MTML query) by colorizing desired tags in a web-based tag cloud interface.
When a user clicks and holds the left mouse button (or presses and holds his/her finger on a touch
screen) on a desired tag, the color of the tag will change cyclically according to a color map
(from dark blue to bright red), which represents the level of preference (from 0 to 1).
In this way, the user can easily organize and check the query of multiple tags with multiple levels
of preference through the colored tags. To effect
MTML content-based music retrieval, we introduce three methods, namely "autotag", "fold-in", and "emsemble".
The content-based music search system is implemented
on the MajorMiner dataset, which consists of 2,472
10-second music clips. The labeled tags are blind in the music database. The system automatically index the music pieces only based on the audio content.
