BilAudio-7 is an MPEG-7 compatible, segment-based audio database management system that supports complex multimodal queries in an integrated way. An MPEG-7 profile is developed to represent the audio files by decomposing them into Audio Segments. The MPEG-7 compatible XML representations of audio files according to this profile are obtained by the MPEG-7 compatible audio feature extraction and annotation tool of BilAudio-7, and stored in a native XML database. Users can formulate text-based semantic, low level, temporal and composite queries on an intuitive, easy-to-use Visual Query Interface, whose Composite Query Interface can be used to specify very complex queries containing any type and number of audio segments with their descriptors. The multi-threaded Query Processing Server parses queries into subqueries and executes each subquery in a separate thread. Then, it fuses subquery results in a bottom-up manner to obtain the final query result. The whole system is unique in that it provides very powerful querying capabilities with a wide range of descriptors and multimodal query processing in an MPEG-7 compatible interoperable environment.
This website aims to reflect the current status of the BilAudio-7 system, which is under continuous development to incorporate more features and foster its performance.
In the following sections, we present the details of the BilAudio-7 system.
