abstract = {The value of social media in crises, disasters, and emergencies across different events, participants, and states is now well-examined in crisis informatics research. Previous research has contributed to the state of the art with empirical insights on the use of social media, approaches for the gathering and processing of big social data, the design and evaluation of information systems, and the analysis of cumulative and longitudinal data. While some studies examined social media use representatively for their target audience, these usually only comprise a single point of inquiry and do not allow for a trend analysis. This work provides results (1) of a representative survey with German citizens from 2021 on use patterns, perceptions, and expectations regarding social media during emergencies. Furthermore, it (2) compares these results to previous surveys and provides insights on temporal changes and trends from 2017, over 2019 to 2021. Our findings highlight that social media use in emergencies increased in 2021 and 2019 compared to 2017. Between 2019 and 2021, the amount of information shared on social media remained on a similar level, while the perceived disadvantages of social media in emergencies significantly increased. In light of demographic variables, the results of the 2021 survey confirm previous findings, according to which older individuals (45+ years) use social media in emergencies less often than younger individuals (18-24 years). Furthermore, while the quicker availability of information was one of the reasons for social media use, especially the potential information overload was a key factor for not using social media in emergencies. The results are discussed in light of the dynamic nature of attitudes regarding social media in emergencies and the need to account for heterogeneity in user expectations to build trustworthy information ecosystems in social media.},

abstract = {Despite the merits of public and social media in private and professional spaces, citizens and professionals are increasingly exposed to cyberabuse, such as cyberbullying and hate speech. Thus, Law Enforcement Agencies (LEA) are deployed in many countries and organisations to enhance the preventive and reactive capabilities against cyberabuse. However, their tasks are getting more complex by the increasing amount and varying quality of information disseminated into public channels. Adopting the perspectives of Crisis Informatics and safety-critical Human-Computer Interaction (HCI) and based on both a narrative literature review and group discussions, this paper first outlines the research agenda of the CYLENCE project, which seeks to design strategies and tools for cross-media reporting, detection, and treatment of cyberbullying and hatespeech in investigative and law enforcement agencies. Second, it identifies and elaborates seven research challenges with regard to the monitoring, analysis and communication of cyberabuse in LEAs, which serve as a starting point for in-depth research within the project.},
