An Overview of A Crime Detection System using the Art of Data Mining

摘要

To predict crime and analyze crime activity we needto proceed with a systematic approach with data mining. Byusing a data mining system one can predict locationsthat have ahuge probability. And one also can inward eye by using thismethod. It will increase the computerized systems.Our mainproblem is that we are looking at the crime occurrences but notat the key factors of crime. If we use data mining we can formany unstructured data to structured data.By which we can findalso some prediction before the crime. We can set a bridgebetween computer science and criminal justice board using thedata mining process by which we can catch the factor very fastand also very easy. Culprits also are divided based on their data.Crime and illegal services are increasing rapidly now. Wesuggest a methodology by which we can detect culprits, predictcrime by analyzing previous crime reports of the regions. Forestablishing this we need crime data from police stationwebsites, govt. crime websites etc. Usingthe Na?ve Bayesianalgorithm on these pre-processed data we can easily predict thestat of crimes. With this system we can establish a secure societywhich will free from crime and people can lead their lifesoundly and also happily.So that we need this data miningsystem and it will increase the usage of computer science andengineering in this era of science. We propose to the predictionof real-time. Though it will difficult to get accurate cause crimesare doing their crimes using different and complexmethods.They are also clever.But the bridge of data between thepolice station and system of data mining will report aboutfurther and upcoming crimes. And for easy understanding ofthe police government we need to use graph data mining so thatthey will easily get points. This paper will describe kinds ofcriminal activities and criminal pathway methods after a crimewhich we will solve by using the data mining system. SO, weneed to locate the maximum crime location area first. We canalso detect the hotspot area and will get some data also fromsocial sites. Data analysts of crime can help the law departmentto solve this problem.The Law department can also reducecrime hotspots. Using this method we need to extract previouscriminal data. So, the bridge between computer science and thelaw will help the world to free from crime.
