Periodic Reporting for period 2 - PREVISION (Prediction and Visual Intelligence for Security Information)
Periodo di rendicontazione: 2020-09-01 al 2021-12-31
a) A collection of over 20 data analytics tools, capable of processing different types of heterogeneous data sources and over 37 different types of data (including video, web, darkweb, telecom, network, financial, traffic, and others).
b) A powerful ontology comprising almost 1000 different classes for representing crime events and actors, combined with an extensible Semantic Reasoner capable of fusing and inferring semantic information.
c) An integrated and scalable platform that incorporates and links all developed tools together, allowing to compose workflows and service bundles
d) A common web-based Human-Machine Interaction environment, integrating and harmonizing the visual outputs of different tools.
e) A high-TRL tool for crawling, analysis and detection of stolen cultural objects, called ARTE-Fact.
f) Demonstration and evaluation of developed functionalities in 5 representative use cases (anti-radicalization, protection of public spaces, fighting of cyber-enabled crime, identification of fraudulent companies, mitigating illicit trafficking of cultural goods) in multiple iterations across different phases of the project.
g) Organization of a series of 17 online, physical or hybrid workshops for demonstration, feedback and evaluation.
h) Establishment of an online training portal.
i) Clustering and collaboration with 12 other security research projects, publication of 17 peer-reviewed papers, production of 1 white paper on knowledge engineering, and participation in over 25 dissemination events.
j) Development and application of comprehensive ethics guidelines, and publication of a multi-stage societal acceptance study as a policy paper.
Starting from the data layer, PREVISION allowed the use of data crawling functionalities in a secure, controlled and supervised manner, enabling investigation of web and darkweb seeds. A flexible Extract-Transform-Load (ETL) component enabled the transformation of various data types into a common data representational model implemented in the form of an ontology. A series of individual analytics tools worked on various modalities to extract useful and meaningful information. For instance, in terms of video analytics, PREVISION advanced on object detection and tracking by investigating a novel hybrid representation of shallow and deep representation features. For action recognition, the goal-based descriptors were extended with spatiotemporal texture. For crisis event detection, PREVISION investigated the implementation of spatio-temporal techniques under a deep learning scheme for the detection of crisis events in near-real time. For face recognition, PREVISION leveraged facial points detection and a combination of shallow features with a deep convolutional framework. In terms of text analytics, PREVISION produced advances in the domains of text feature extraction, jargon detection, text mining and radicalization detection. In the domain of social media analytics, PREVISION developed novel community detection, key actor identification and actor identity resolution functionalities which were tested using publicly available datasets. Cyber analysis tools were also incorporated, making steps for the mitigation of hybrid security threats. PREVISION also developed a toolkit to identify radicalization tendencies in society at an early stage and, based on this, to develop risk forecasts that allow security authorities to take preventive action. At the semantic level, by developing a powerful Semantic Reasoner, it proved possible to implement complex queries, revealing hidden patterns, correlations and anomalies within vast amounts of data. Visual analytics were facilitated through the design of a modern web-based HMI, enabling different forms of visualization and user interaction.
PREVISION has established an open and future-proof platform for providing cutting-edge practical support to LEAs and practitioners in the fight against terrorism, organised crime and cybercrime, creating a number of impacts on societal and innovation aspects, such as:
1. Contribution to the Security Union.
2. Innovation capacity and integration of new knowledge.
3. Strengthening the competitiveness and growth of companies.
4. Societal impact(s), including alleviation of first/second/third order victimisation and reduction of financial costs.
