Automatic Ontology Generation based on Semantic Audio Analysis

The automatic ontology generation system performs two main tasks: i) musical instrument recognition, and ii) the construction of instrument concept hierarchies. In the first part, the hybrid system uses either a Multi-Layer Perceptron neural network, or Support Vector Machines to model the relationships between instruments (e.g., violin) and their attributes (e.g. bowed) using content-based timbre features. In the second part, the output of the instrument recognition system is processed using Formal Concept Analysis to construct a conceptual hierarchy for musical instruments.

Automatic ontology generation system based on audio features.

The system is based on a general conceptual analysis approach and can be applied to any research fields that deal with knowledge management issues.
