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].
