USING DATA MINING TECHNIQUES

Abstract - Criminology is an area that focuses the scientific study of crime and criminal behavior and is a process that aims to identify crime characteristics. It is one of the most important fields where the application of data mining techniques can produce important results. A broad analysis of unlawful activity reveals that all criminal behavior shares a common set of universal principles. A micro simulation model can be drawn out by interlinking the universal principles with the attributes of the individuals for profiling the criminal behavior. These principles remain constant; however, they manifest differently for each individual depending on personality, criminal activity, extrinsic factors and the attributes of individuals. This paper elaborates the criminal behavior analysis of the offenders by using data mining techniques. Index Terms - Universal Principles, Attributes, Crime Module. I. INTRODUCTION Criminologist proposed that criminality is not inherited, it is learned, the way it is learned, is through direct operant conditioning, and imitation or modelling of others. This application was seen throughout the senseless civil unrest. Imitation or modelling can play a big part in whether or not a person is likely to commit a crime. A nwnber of factors influence the modelling process. For instance, one tends to imitate those one likes, respects or admires. Imitation is also more likely if the observer sees the model being reinforced, if the model displays pleasure or enjoyment or if imitating the model in itself is being rewarded. An observer, though, may do the reverse or opposite of what a model does if he or she dislikes the model, sees the model punished or if Imitation of the model is being punished. Psychologists who are involved in profiling criminal behaviour are likely to have frequent experience with it. Better understanding of the criminal mind and behavior is essential to cope with crime. Criminal Investigative Analysis (CIA), also known as criminal profiling [1], is an investigative tool used within the law enforcement community to help solve violent crimes. The analysis is based on a review of evidence from the crime scene and from witnesses and victims. The analysis is done from both an investigative and a behavioral perspective. The analysis can provide insight into the unknown offender (characteristics and traits) as well as investigative suggestions and strategies for interviews and trial. A CIA cannot replace a thorough investigation; and the accuracy and detail of a CIA is limited by the accuracy and detail of the information on which it is based. CIA does not use crystal balls or psychic experiences; it is a logical, systematic approach for analyzing behavior. Criminal psychology is beginning to focus on modeling the effect of mental processes and attributes of individual on offender behavior. Although criminologists and psychologists can identify relevant input and output variables, the processes underlying criminal behavior are only partly understood. Criminal behavior tends to be relatively predictable. By making use of the data, anticipation and prevention of crime can be much more proactive.
