Abstract [en]

Harmful communication, such as toxic language and threats directed toward individuals or groups, is a common problem on most social media platforms and online spaces. While several approaches exist for detecting toxic language and threats in English, few attempts have detected such communication in Swedish. Thus, we used transfer learning and BERT to train two machine learning models: one that detects toxic language and one that detects threats in Swedish. We also examined the intersection between toxicity and threat. The models are trained on data from several different sources, with authentic social media posts and data translated from English. Our models perform well on test data with an F1-score above 0.94 for detecting toxic language and 0.86 for detecting threats. However, the models' performance decreases significantly when they are applied to new unseen social media data. Examining the intersection between toxic language and threats, we found that 20\% of the threats on social media are not toxic, which means that they would not be detected using only methods for detecting toxic language. Our finding highlights the difficulties with harmful language and the need to use different methods to detect different kinds of harmful language.

Abstract [en]

This work-in-progress presents the design of an XR prototype for the purpose of educating basic cybersecurity concepts. We have designed an experimental virtual reality cyberspace to visualise data traffic over network, enabling the user to interact with VR representations of data packets. Our objective was to help the user better conceptualise abstract cybersecurity topics such as encryption and decryption, firewall and malicious data. Additionally, to better stimuli the sense of immersion we have used Peltier thermoelectric modules and Arduino Uno to experiment with multisensory XR. Furthermore, we reflect on early evaluation of this experimental prototype and present potential paths for future improvements.
