Together with an interdisciplinary research team, Tamar Edry and Oliver Gruebner analysed a large, anonymised dataset of tweets that were geo-tagged. From this, they developed a tool that maps geographic clusters of negative emotions over time, in line with the spread of the COVID-19 pandemic. Automated activities - especially "bot" accounts - were filtered out.
With this innovative approach, spatial hotspots of emotional stress can be monitored in real-time and made accessible in interactive maps over time. This could be helpful for governments, NGOs, health experts and other stakeholders in order to specifically prepare measures in those regions where they are most urgently needed.
