Linkage Analysis Using I2
The linkage analysis project was taken on in January of 2013 with the purpose of combining all of the existing offender data sets available to the Washington College GIS Program into one comprehensive database. The resulting combination of this data has allowed us to create link charts. These link charts reveal connections between criminals that would not have been possible to find without the use of Linkage Analysis tools such as IBM’s i2 suite.
So what is i2? The i2 suite consists of three platforms; Analyst Notebook, iBase and the Intelligence Analysis Platform (IAP). iBase is the application that stores all of the offender data, Analyst Notebook is a desktop application that allows users to create link charts and perform complex social analysis, and IAP is a simpler web based version of Analyst Notebook which will be available online to all of the Maryland law enforcement community.
Since the beginning of the i2 project, we have started working with smaller police agencies to fulfill “Spider Mapping Requests”. This works much like our “Maps on Demand” program, in which a Maryland Law Enforcement Agency sends us data to map, we fulfill the request, and send it back to that agency. We are currently providing such projects on a routine basis to Harford County Police Department and Anne Arundel County Police Department.
In addition to creating custom link charts for law enforcement we have implemented the IAP web portal with the ability for law enforcement to create their own link charts on the Maryland Offenders Management System (MOMS). Using IAP law enforcement users statewide are able to browse our data repository via the web, and even make simple link charts inside IAP.
