Ontology is knowledge management structure that represents domain knowledge in machine interpretable format. Ontologies built hierarchical structure of domain knowledge. However, manual creation of ontology for domain of musical instrument is laborious and challenging task. To overcome these problems ontology creation process can be made less dependent on human supervision by using concept analysis and conceptual analysis techniques. To determine optimised codebook of LSF and MFCC K-mean clustering is used. Classification will base on MLP and SVM. FCA builds the hierarchical structure of musical instrument ontologies.
