Abstract

An embodiment of the invention discloses a method and a device for text classification. The method comprises: acquiring an affective characteristic word from an input text; acquiring an affective aptitude degree of the affective characteristic word according to a synonym storehouse constructed in advance; and classifying the text according to the affective aptitude degree of the affective characteristic word. The embodiment of the invention is used to acquire the affective aptitude degree of the affective characteristic word in the text for text classification according to the synonym storehouse constructed in advance and improves the accurate degree of judging the affective aptitude degree of the words.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a text classification method and device. Background technique [0002] With the rapid development of communication technology and the popularization of the Internet, effective processing and filtering of Internet information has become an important research topic. [0003] The study of semantic orientation came into being under this background. The so-called semantic tendency of words is to calculate a measurement value for the degree of praise and criticism of words. For the convenience of statistics and comparison, the more commonly used practice is to specify the measurement value as a real number between [-1, 1]. If the measurement value is higher than a certain threshold, it is judged as a positive tendency; otherwise, it is judged as a derogatory tendency. In addition, the semantic orientation of a text can be obtained by averaging the semantic orientation values ​​of w...
