This webinar will discuss two social network analysis (SNA) projects that the Philadelphia, Pennsylvania Police Department (PD) undertook. The first project examined the extent of shared connections among shooting victims through network analysis; in particular, the analysis examined cross-divisional connections by combining the network analysis and geographic information systems (GIS). The second project applied SNA to understand connections among gangs at the group-level across the city. The project focused on 1) identifying the extent and nature of positive/negative connections among gangs, and 2) developing a web-based application that visualizes the result of SNA on a map.
