Design And Application Of Police Big Data System Based On Relationship Mining

With the development of social economy and the acceleration of the information age,the mobility of the population is increasing.Criminals often use convenient means of transportation to commit crimes across regions.After the case,they flee to other places quickly.The means of committing crimes are getting higher and higher,and the ability of anti-investigation is becoming stronger and stronger,which increases the difficulty of solving cases by the police.In order to improve the efficiency of solving police cases,public security departments should make full use of big data technology.Through the analysis and judgment of massive data,applying the technology of relational data mining,public security departments can dig out the clues hidden behind the data,provide an important basis for combating crime,and thus promote the scientific development of public security work.On the basis of investigating the police system and sorting out the relevant literature,this paper introduces the theory of big data,data mining theory and social network theory as the theoretical basis.Then,the design of the police big data system based on relation mining is carried out.The necessity and feasibility of the construction,the goal and content of the construction,the overall positioning of the system,the functional and non-functional requirements are analyzed.The overall structure,main performance indicators,hardware essentials,comprehensive query and statistical analysis of the police big data system based on relation mining are pointed out and designed.Finally,the application of big data system of police affairs based on relation mining is expounded.The application of big data system of police affairs based on relation cloud map,big data system of police affairs based on connection network,big data system of police affairs based on vehicles of big data system of police affairs based on relation mining are mainly introduced.Through the introduction and elaboration of the application of the police big data system based on relationship mining,the development of the police big data application is promoted,and a new direction is opened up for the research in the field of crime analysis.It is of great significance and value in maintaining social stability,accurate attack and police management.
