RISE_SMA forms an interdisciplinary, international network combining excellent scholars and practitioners to enable vigorous knowledge sharing and to develop solutions for contemporary challenges for Social Media Analytics (SMA). Advanced theoretical approaches and methods of analyzing social media data are especially relevant for two domains addressed in RISE_SMA: society and crisis communication. Recently, social media communication gained immense impact on society and decision-making at all levels. It offers the potential for new forms of public discourses but also challenges societal cohesion phenomena like fake news and vicious social bots. During uncertain events such as natural disasters or human-made crises, social media communication plays an increasingly important role for citizens and emergency service agencies. RISE_SMA attempts to uncover communication patterns and suggest best practices to seek and share information in precarious situations.
