| Abstract: | According to the characteristic of network massive data, the traditional histogram algorithm was improved. The principle axis search tree is utilized for pre-processing and the two-stage method is presented for audio retrieval. Experimental results show that the two proposed methods can significantly improve the search speed and precision. |
