4.3 Experiments for Music Summary Detection

In this section, three metrics precision, recall and F measure are adopted to evaluate the method we proposed. They are defined as follows:

(6)

where x and {zj} refer to the summary snippet detected by our method and all summary snippets labelled by human respectively. Snippet zi has the largest overlap with x. We define that the proportion of summary snippet detected incorrect summary snippet as precision, which is represented by Pp. And the proportion of correct summary snippet labelled by a human in the summary snippet we detect is defined as recall, which is denoted by Pr.

Our proposed method for summary detection is compared with Matthew and Jonathan [20] and Bartsch and Wakefield [4] on the 240 popular songs. The results are shown in Table 2. Obviously, the performance of our method outperforms the two baseline methods. The precision, recall and F measure reach 73, 85 and 83% respectively.Table 2Experimental results for music summary detection
