An Accurate Classification Method of Police Intelligent Construction Level Based on Multi-scale Levenshtein Distance and Variable Weight

Aiming at the issue of inaccurate development positioning and uneven construction level of policing Intellectualization in different regions, a precise classification method for policing Intellectualization construction level based on multi-scale Levenshtein distance and variable weight was proposed. According to the evaluation value characteristics of indicators at all levels in the evaluation index system, a variable weight multi-scale evaluation value feature sequence was constructed. The feature sequence of Levenshtein distance value was taken as the objective function for classification and evaluation. Based on the survey data of 15 prefecture level cities' public security bureaus in Province A in the east coast of China, the case verification was carried out. The results show that the classification results had multi-scale similarity of general objectives, primary indicators and secondary indicators at the same time, and could also be classified according to the actual needs or focus of the evaluation by adjusting the weight.
