[Objective] For complaint text has the characteristics of informative, unstructured, weak regularity etc., the current information management of city complaint needs an efficient classification method to improve the efficiency of the management staff.[Methods] Analyze the characteristics of complaints and go for text preprocessing; Then use the parser, synonyms forest, and through the contribution of the document to filter guide word; At last, calculate the guide word weighting coefficients with TF-IDF, use VSM model to represent guide words and use SVM model to classify the complaint text. [Results] In multiple categories of complaint text, the average precision of the method is up to 82.1% and the average recall is up to 82.3%. [Limitations] Thesparsity of complaint text affects the classification results to a certain extent.[Conclusions] The experiment results show that the method is effective and feasible in the text classification of complaints, and it can improve categorization effect of thecomplaint text.
