QUIN: Providing Integrated Analysis Support to Crime Investigators

Crime investigators heavily rely on their largeknowledge of criminal behavior. When investigating a new case, applying this knowledge can lead to cognitive overload andtunnel vision. Some support systems are developed to searchthrough historical data and knowledge more easily, but stillrequire the investigator to put all the pieces together and ask theright question. In this paper we present QUIN, a support systemthat can model different crime scenarios and reason about whathappened. For this it uses expert knowledge and historical data. Investigating with QUIN provides a solid overview of currentknowledge of the case, a clear view on likely scenarios andsuggestions on what to look for in order to advance theinvestigation.
