Abstract

The invention provides a method and device for obtaining a group chat text classification word bank. The method comprises the following steps of obtaining a plurality of different types of sample group chat texts, carrying out the preprocessing such as word segmentation and stop word removal on a sample group chat text, carrying out the word vector weighting on the preprocessed group chat text, converting the group chat text into a high-latitude word vector, then carrying out the dimension reduction processing on the word vector through a gradient dimension reduction algorithm, and obtaining atarget lexicon of the sample group chat text. According to the obtained target word bank, the collected test group chat text can be classified. By means of the method for obtaining the group chat text classification word bank, the target classification word bank needed by the user can be obtained, then the collected group chat texts can be classified through the target classification word bank, and particularly the group chat texts of various illegal crimes can be accurately distinguished.
