Research Projects

There are several Research projects developed in the Engineering Cell of Knowledge, in UNIFOR, under the orientation of Dr. Vasco Furtado. Work in carried out on the aspects linked to the acquisition, representation and exploration of knowledge, for the production of intelligent systems, focusing applications linked to the Administration of Knowledge, the Mining of Data in Grid, Web Semantics and Technologies for Public Security.

Projects of the Area of Law Enforcement:

One of the crucial questions regarding crime and violence control in urban centers is how to gauge the actual impact of certain police management strategies upon the regulation of the rates of criminality. This is indeed a question difficult to be answered, as it seems that the effectiveness of a certain law-enforcement policy on a given metropolitan region depends, directly or indirectly, upon an array of factors, ranging from the levels of concentration of richness to the physical organization of the urban center under consideration. In such a context, it is quite consensual that police patrolling can be considered as one of the best well-known means for implementing preventive strategies towards the combat of an assortment of crimes, mainly those involving violence practices (such as bank assaults, thefts, armed robbery, gang fights, drug dealing, environmental degradation, and kidnapping).

The conceptual basis for preventive approaches and the development of some pro-active policing strategies can be found in “Routine Activities Theory” (Cohen and Felson, 1979), which attempts to explain the evolution of crime rates not only through the characteristics (psychological profiles) of the offenders, but also through the circumstances in which crimes occur. Basically, Cohen and Felson (1979) point out that, in order for a criminal act to take place, three elements must coexist: a motivated offender; a suitable target, either an object or person that can be attacked; and the absence of capable guardians, in charge of the preventive actions. The criminality model derived by the authors is then based on an economic equation involving the aforementioned elements. A direct conclusion of such work is that criminal offenses are related to the nature of everyday patterns of social interaction. Another is that the police force is, naturally, the central element for promoting public safety by means of diligence and dissuasion.

In our work, we have investigated some behavioral aspects of criminality by making use of agent-based simulation having in mind both educational and decision-support purposes. Agents representing criminals, police officers, and targets, as taking part in a multiagent society, had their main properties, profiles, and behaviors characterized and modeled. We are investigating different approaches to different problems in police patrol. They are:
