An association model for implicit crime link analysis

Abstract

Link analysis has been an important tool in crime investigation. Explicit social links, such as kinship, financial exchange, and telephone connection, are often used to construct links between criminals. However implicit links, such as modus operandi, times of day, and geographic relationship, are seldom used to establish relationships between crime entities. This paper proposes an association model based on modus operandi and geographic relationship to establish links among crime cases and criminals. A data collection from local police department is used for experiment to evaluate the performance of the proposed approach. © 2010 Springer-Verlag.
