Vertical Semantic Discovery: The SICH Approach on NPS

The SICH Project specific objective is to develop new strategic tools and assessment techniques, based on semantic analysis on texts, to support the dynamic mapping and the automatic identification of illegal content over the Net. Xenophobia/Racism, illegal online Gambling and Novel Psychoactive Substances (NPS) are the main areas of reference. In this paper the authors present a systems based on a semantic engine running an ontology, based on a criminological analysis of NPS phenomenon. The system, after crawling the web, classifies key elements of NPS crime, not necessarily representing illegal content or criminal activity evidence. Thanks to this approach, the system aims to dramatically reduce the learning time of the key factors of illegal activities, with further reuse of well established web graph and SNA tools to highlight the relevant aspects of the semantic results.
