Design And Application Of Investigation Suspect System

In the current social environment,social security is becoming more and more complex and severe,all kinds of robs,FK,maintenance of stability at the sudden sharp increase of pressure,the means of crime are intelligent,professional and organized,traditional methods of work can not meet the needs of the situation and tasks,with the increasingly complex situation,public security work is facing new challenges.Based on the new big data form,the traditional database technology has begun to appear tired,the technical bottleneck gradually,the response speed more and intelligence analysis and detection of cases more slowly,some application scenarios are completely unsupported.In order to meet the challenges of public security business under the new situation,it is urgent to build a big data police cloud platform in Harbin.The new platform requires the use of big data technology and analysis tools to quickly and effectively complete the analysis of a large number of different sources of data,reveal the interaction between different behaviors,and analyze and predict the action trend of dangerous g roups.To provide a strong technical support for the formation of a comprehensive,full time and space,all-weather dynamic prevention and control system.This article is based on the big data inside and outside the public security department.How to integrate data resources through ETL and integrate disordered data into high quality,meaningful,and associated valuable data sets;Obtaining dimensional data information that can be used for machine learning by using MAPREDUCE for large data queries;The study of machine learning and international general algorithm is studied.Finally,through the training and testing of various classification algorithms,the prediction model algorithm suitable for this system is used for actual combat;The system of suspect touch and row in public security network is established through B/S architecture.This paper mainly completes the function,through the time and place of the case occurrence,delineate the most necessary information of the suspects,and then predict the high crime tendency through the prediction model,and ultimately realize the suspects Mopai system.
