The invention discloses a method and a device for generating a Chinese comparative sentence sorter model and identifying Chinese comparative sentences. The method comprises the following steps: converting each clause containing set comparative keywords in each sentence of a data set into a sequence, and establishing a category tag as the same as the sentence of a corresponding clause for the sequence; obtaining a sequence set; mining a plurality of comparative modes from the sequence set by a sequence mode mining algorithm, and forming a comparative mode set; matching each comparative mode inthe comparative mode set with each sequence one by one, and according to the matching result and the total number of the comparative modes, obtaining a group of characteristic vectors corresponding to each sequence; generating a sorter model according to the characteristic vectors and the corresponding category tag of the sequence; and then identifying a read-in sentence with unknown category through the obtained comparative mode set and the sorter model, and determining whether the sentence is a comparative sentence. By automatically learning the mode characteristics of the comparative sentences, the sorter model is generated and can automatically and effectively identify the comparative sentences in a text.
