Design And Implementation Of Police Intelligence Analysis System Based On Data Mining

With the development of information technology,the emergence of big data,cloud computing,not only brings a lot of convenience to our lives,but also provide a great help for many kinds of high-tech criminal acts.In the police work in the current collection,analysis and assessment of police intelligence,most still remain in the collection and reporting of human use of simple,traditional mode of transmission and storage,the artificial statistics and comparison.In the face of today's complex social situation,how to achieve high proposed"intelligence led" new policing model,the police intelligence service real police combat,the maximum to alleviate the current situation of insufficient manpower,realize precise guidance,precision strike.Early warning of major security,early warning of sensitive information,early prevention of important events,has become an important issue in front of everyone who works in the police intelligence departments.The design and implementation of the police intelligence analysis system is to create a comprehensive application platform for the police intelligence department at the grassroots level,it can realize the basic police handling units and the comprehensive intelligence convenient and efficient communication and coordination,while also providing analysis,such as alarm analysis and dynamic early warning and a number of intelligent aided analysis application,the a set of integrated information systems acquisition,collaboration,analysis,command functions in one,make all kinds of seemingly separate discrete police information into the police intelligence products are valuable content,provide strong support for grass-roots policemen indeed.This paper focuses on the two major themes is that study of the application of knowledge discovery in the work of police intelligence analysis and how to use the information technology to effectively improve the effectiveness of grassroots police work.The main steps are:1 The police information service system construction characteristics,curtent situation and research background is analyzed,and the significance and originality of the research are briefly described;2 Described the main application of knowledge technology and development tools in detail,mainly related to data mining,data warehouse and SQL Server in the data warehouse modeling and data mining application characteristics;3 The feasibility analysis,requirement analysis,system function module partition and security requirements are analyzed;4 The system network topology and hierarchical architecture design,combined with the business process diagram and data flow diagram of each module of the system for the detailed design of the data dictionary are described,and the system of data warehouse model are designed;5 To design the main function modules are implemented spepific details,describes the key modules in the process,and test the selected data,gives a brief description and summary of the test results.In summary,the police analysis system for the grass-roots police intelligence agencies to build a comprehensive application platform close to the actual combat.The system has been put into use,to achieve the desired design goals,but also received good results.
