Research on the Application of Cluster Analysis in Criminal Community Detection

Abstract

With the development of China’s economy and technology, the mobility of people enhances rapidly, the trend of crime towards to community and organization. Criminal behaviour is a kind of social behaviour. Many malignant cases, especially those that are highly harmful to the lives and property of the citizens and have bad social influence, are not executed by a single person, but need teamwork to complete. At present, the city’s population base is large, the police force is insufficient, and it is difficult to expedite the investigation of suspicious personnel by conventional methods in a short time. This paper establishes the social network model according to the local telephone call records, and then uses the cluster analysis algorithm looking for people with close links to the criminal suspect to identify suspected criminal accomplices. The cluster analysis algorithm proposed in this paper can help the public security organs filter suspicious people rapidly, narrow the scope of possible criminal gangs, and improve the efficiency of detected cases.
