The Research Of Criminal Behaviors In Social Networks

As a social phenomenon, crime is an inevitable development with society changes, and it shows a dynamic process of changes. In some ways, the crime has a characteristic of regionalization. To any a specific region, its geographical environment and social status quo determine the main crime's types and trends directly. Like other reasonable things, there are not no reasons which lead to the crime either. All criminal cases can not happen without corresponding selections of timings, locations and other relevant factors. For lack of certain conditions and factors, crimes can't happen.The crime, as an individual product against the country, is a human behavior which is required to give negative by our country firstly. Therefore, it has been concerned by politicians, sociologists, jurists and other scholars widely. In order to prevent and combat the crime effectively, scholars from different levels of researches, are devoted a lot of hardwork. The main study of the crime is the study of criminal behaviors. However, in our country, the criminal behaviors'research have been studied by the Criminal Law and Criminology. Criminal law basing on the premise of certainty makes researches on criminal behaviors as elements that are requisite, while criminology gives researches on the criminal behavior as a social phenomenon, showing a briefly, non-element-type behavior. But both of them don't take crime as the only specialized study. In other words, their researches on criminal behaviors are only as means of achieving the main purpose of their own means or premise, and there is no systematic research for criminal behaviors of themselves. So, in some respects, the predecessors'researches on the criminal behavior are lack of a macro, systematic approach, and have certain limitations.Complex networks are the basic topology of a large number of complex systems that exist in the real world. From overall characteristics, they are between rule networks and random networks, with small-world effects and scale-free characteristics. From the overall point of researches, they take a common and universal way of different complex networks as an object of study. Hence, we could make researches on criminal behaviors with the complex network's theory.This paper is not focused on trying to set up a new complex network model, but to set up the criminal location relationship's network in reference to the existing network model. By the research of the criminal location relationship's network, a real weighted network, we found some means and knowledge that are ignored by experts and scholars in the course of researching on criminal behaviors. The main research content of this paper is as follows:First, build the criminal location relationship's network in use of the real data, and obtain the network structure graph of the criminal location relationship's network.Second, make a projection from the criminal location relationship's network to the criminal location relationship's network based on cases and the criminal location relationship's network based on number. Obtain network structure graphs of them.Third, analyze topologies of the criminal location relationship's network based on cases and the criminal location relationship's network based on number, and make simulations of them; found that the vertex weight distribution and edge weight distribution have a characteristic of power-law distribution.Fourth, combined with Criminal Law, Criminology and other related knowledge; analyze the main features and factors which affect criminal behaviors; make suggestions for judiciary and other relevant management departments to prevent and combat crime. In addition, make a summary of this article, and make a prospect to the next job.
