The Research And Application Of Data Mining In Crime Analysis For Police

Data mining technology is a hot topic in the fields of artificial intelligence and database in recent years, the research in many fields, but the research on police work is still inadequate, so this paper uses the data mining technique used in crime analysis as the main research.At present, with the rapid development of social politics, economy and science and technology, modern crime shows characteristics of speed, intelligent, high-tech crime, from the overall trend, since the founding of new China, our country had five criminal peak, with every crime wave is a new crime appears at the same time, the rapid rise of intelligent crime cases, the proportion has increased. In this case, using data mining techniques to find the new rules and promptly applied in police work, to enhance law enforcement efficiency and rapid reaction capability, timely preventing and combating crime, has become an urgent problem to solve in the public security work.But the application of the traditional Apriori algorithm and ID3 algorithm of decision tree in the work of public security has not solve the problem, such as not to produce new criminal offence rules, easy to overlook the less proportion but harmful cases related rules, in light of this situation, this paper has carried on the analysis and the research on data mining technology in the crime problems in analysis, the sensitivity of the Apriori optimization algorithm and weighted Apriori based optimization algorithm, based on the analysis of the problems existing in the traditional ID3 algorithm on crime analysis is proposed on the ID3 optimizationalgorithm is sensitive coefficient based on B.In the complete research and analysis, the author presents a new set of crime analysis model that four staff level model, the model is applied to the decision tree for mining association rules and clustering analysis based on crime, this crime information analysis rules and clustering system results have certain reference value the police organ case based processing, and provide decision support for managers.
