City security level mining based on massive criminal data

In this work, we focus on the problem of city security based on the massive amount of crime statistics data. Combined with city crime statistics data, fuzzy comprehensive evaluation method is used to judge the safety grade of the city, and the weight of the evaluation set is calculated based on the analytic hierarchy process. The experiment results show that fuzzy comprehensive evaluation method is effective and feasible, and it can be widely used in the evaluation of general city security level.
