Cyber Social Threats 2021: AI, Covid-19 Vaccine, Detection and Countering Strategies

In recent years, online platforms have been utilized for promoting harmful content and behavior such as extremism, harassment, mis/disinformation, human trafficking, genderbased violence among others affecting our society, often leading to real-world events. Such content and behaviors are inherently complex, making the recognition of these narratives challenging for researchers as well as social media companies. The Cyber Social Threats (CySoc) Workshop 2021 aimed to facilitate a rich forum for researchers and practitioners from both academia and industry in the areas of computing and social science, to discuss novel avenues for research on interdisciplinary aspects of harmful communications on social media, to exchange ideas and experiences, and to identify new opportunities for collaboration. The second edition of this workshop was well-received and very successful in providing a platform to explore future directions, possible research ideas, and collaborations, as it was for the first edition last year (2020)
