OMEGA: a Brazilian case of supporting system to police investigation activities

The public security issue is one of the main concerns in the Brazilian Society. The Civil Police's Intelligence Department idealizes OMEGA, as a tool to support the investigative activities by providing fast access to consolidated and valuable information according to the users needs. OMEGA achieves this challenge by using data integration to a unique database and also an artificial intelligence method that retrieves crime reports through conceptual and contextual analysis of texts inserted in an open-entry field. OMEGA is a Web application accessed mainly by sheriffs and investigators through the police intranet. OMEGA is currently being in restricted use to approximately 100 police departments in order to give the development team a better control of its deployment.
