Special Issue Information

Dear Colleagues,

There are numerous social networks such as Facebook, LinkedIn, Google Plus and Twitter and an abundance of valuable information in the form of chat text, images, videos, networking graphs of individuals, etc., which can be used to prevent, detect and solve crimes. Moreover, there are digital documents, reports, activity logs, images and biometrics information that are left as traces by criminals and there is also information archived from police entities. All of these data can be collected, represented and used as digital crime evidence in preventing and solving crimes. Crimes are not necessarily digital, but the traces left behind are or they can be digitized. There is a need for representing such digital information in a meaningful way and making sense of it in order to support the process of crime investigation and prevention. Ontologies and knowledge graphs, semantic similarity, text mining and other Artificial Intelligence approaches are useful for such purposes. It is possible to benefit from ontologies and knowledge graphs in different ways: intelligence gathering, reasoning over data, smarter searches and comparisons, open data publication purposes and the overall management of the crime solving and prevention process. In this Special Issue, we are looking for contributions that provide innovative methodologies, techniques, tools, approaches and insights into representing and reasoning with crime information. Keeping the chain of custody for all types of digital evidence and authenticating it in order to be admitted in court is also important to provide solutions. Biometrics, GDPR, data privacy issues, ethics and the legal aspects of crime prevention, detection and investigation are also of interest.

This paper presents an ontology that involves using information from various sources from different disciplines and combining it in order to predict whether a given person is in a radicalization process. The purpose of the ontology is to improve the early detection of radicalization in persons, thereby contributing to increasing the extent to which the unwanted escalation of radicalization processes can be prevented. The ontology combines findings related to existential anxiety that are related to political radicalization with well-known criminal profiles or radicalization findings. The software Protégé, delivered by the technical field at Stanford University, including the SPARQL tab, is used to develop and test the ontology. The testing, which involved five models, showed that the ontology could detect individuals according to “risk profiles” for subjects based on existential anxiety. SPARQL queries showed an average detection probability of 5% including only a risk population and 2% on a whole test population. Testing by using machine learning algorithms proved that inclusion of less than four variables in each model produced unreliable results. This suggest that the Ontology Framework to Facilitate Early Detection of ‘Radicalization’ (OFEDR) ontology risk model should consist of at least four variables to reach a certain level of reliability. Analysis shows that use of a probability based on an estimated risk of terrorism may produce a gap between the number of subjects who actually have early signs of radicalization and those found by using probability estimates for extremely rare events. It is reasoned that an ontology exists as a world three object in the real world. Full article
