 The present invention is described below with a simplified embodiment.
 In this embodiment, the resources are video text resources. Collect video resource text introductions and text annotations downloaded by web crawlers from major websites, a total of 9 video texts, analyze and organize video text data, and classify them into corpus training sets according to 3 categories. The video text in the training set is segmented by the word segmentation tool, and the stop words are removed, and the word frequency of the corresponding feature item is counted.
 Table 1 is a statistical table of word frequency of feature items of video text.
 Table 1
 Among them, T11~T13 are three texts of category 1, T21~T23 are three texts of category 2, and T31~T33 are three texts of category 3. t 1 , t 2 , t 3 , t 4 , t 5 It is part of the feature items in the T11~T33 text set. Analyzing the feature items in Table 1, the weight distributio...
