Evaluation
¡For music retrieval:
¡For a test set of 183 songs, 10~12 pitch
transitions are sufficient to discriminate 90% of the songs
¡For speech query:
¡Method a:
Here we assume that the natural language query is a bag of
words with stop word removed (Ricardo, 1999). Currently, most search
engines are based on this approach.
¡Method b: We applied our query model to extract
CSS and employed the multi-tier mapping approach to extract and correct the
errors in the CSS components.
