ORCA: Organization, Relationship, and Contact Analyzer 

Organization, Contact, and Relationship Analyzer (ORCA) is a piece of software designed to aide intelligence analysis for law enforcement operations against violent street gangs using new algorithmic techniques in social network analysis. Specifically, it can determine "degree of membership" for individuals who do not admit to membership in a street gang, quickly identify sets of influential individuals, and identify criminal ecosystems by decomposing gangs into sub-groups.  Currently, we are working with the Chicago Police Department to explore the use of the system for real-world policing.  This project is funded by the Army Research Office (2GDATXR042).
