Crime Factor Associativity Analysis Based On Data Mining Technology

Criminal crime is relevant to criminal personal external factors (such as family background, growth experience, education, etc), with the physical condition and other internal factors related. This paper tries to introduce the data mining technology used in crime factor analysis to get some crime, law, for the prevention and control of crime to provide valuable information, which has the important research value and practical significance.The paper aim at 600 cases of criminal criminals personal background information, the genetic data and psychological questionnaire information, cooperating with chongqing public security bureau and our school environment system biology research institute, the crime psychology, cooperation criminal behavior of data mining technology and the method of combining the key factors in the analysis of the relationship between crime. Paper describes omissions, noise data, not data consistent data and continuous attribute data preprocessing method, and carried out the attribute reduction and rule mining research research; According to the attribute reduction, will Apriori algorithm and the rough set method is proposed, which combines AprioriRS algorithm, and with conventional algorithms for the contrast. AprioriRS algorithm using itemsets pretreatment of classification of database of transactions all the items set, and reduced the pretreatment of candidate set a possibility. In the process of screening itemsets, using rough set theory of knowledge reduction approaches to a set of reduction, to avoid the DuoCi repeat scanning database.The paper detailed instructions from the data preprocessing to how to make the data collection features about Jane and association rules mining and the process of analysis, the mining association rules results are analyzed and screening, and discussed the rules acquired in chongqing area of the specific value. Research work to the public security organ case processing has some reference value, and to prevent criminal crime and to carry out their legal system education and propaganda work has the positive role.
