Since an ever-increasing part of the population makes use of social media in their day-today lives, social media data is being analysed in many different disciplines. The social media analytics process involves four distinct steps, data discovery, collection, preparation, and analysis. While there is a great deal of literature on the challenges and...

During a crisis, authorities need to effectively disseminate information. We address the problem of deciding how crisis-related information should be published on Facebook to reach as many people as possible. We examine three recent terrorist attacks in Berlin, London and Stockholm. Our specific focus lies with official Facebook pages by municipali...

Information systems such as social media strongly influence public opinion formation. Additionally, communication on the internet is shaped by individuals and organisations with various aims. This environment has given rise to phenomena such as manipulated content, fake news, and social bots. To examine the influence of manipulated opinions, we dra...
Article
Social media have become forums of discussions on political and societal debates in which individual users may forward information or influence others. While prior studies either employed network analyses or surveys to identify opinion leaders and their characteristics, the present investigation combines these two approaches to address the relation...

Social media has become important in shaping the public discourse on controversial topics. Many businesses therefore monitor different social media channels and try to react adequately to a potentially harmful opinion climate. Still, little is known about how opinions form in an increasingly connected world. The spiral of silence theory provides a...

During the coronavirus disease 2019 (COVID-19) pandemic, the video-sharing platform YouTube has been serving as an essential instrument to widely distribute news related to the global public health crisis and to allow users to discuss the news with each other in the comment sections. Along with these enhanced opportunities of technology-based commu...
Conference Paper
In this work we introduce Adversarial Attacks against Abuse (AAA), a new evaluation strategy and associated metric that better captures a model's performance on certain classes of hard-to-classify microposts, and for example penalises systems which are biased on low-level lexical features. It does so by adversarially modifying the model developer's...

When attempting to solve a problem, humans call upon cognitive resources. These resources are limited, and the degree of their utilisation is described as cognitive load. While the number of parameters to be taken into account and to be processed by modern-day knowledge workers increases, their cognitive resources do not. Research shows that too hi...

In recent years, mainstream E-commerce platforms have changed the way consumer goods are merchandized online. While such platforms increasingly discover social elements to drive sales, social media start implementing E-commerce features themselves. This emerging intersection also provides space for bot activity in a Social Commerce (SC) context, wh...

Full-text available
Like many other industries, the media industry has been profoundly affected by social media. The public discuss the news on services such as Twitter, and some celebrity tweets are picked up by journalists and become news stories themselves. Information systems research into information diffusion has largely neglected these cross-platform diffusion...

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.

Project
This DAAD funded research project between the Queensland University of Technology (Australia) and the University of Duisburg-Essen (Germany) examines engagement practices around SoundCloud (which attracts 175 million unique monthly listeners), using big data from SoundCloud and social media. We capture a large dataset of SoundCloud comments as well as tweets and Facebook posts sharing links to SoundCloud, and use a combination of automated content analysis of these comments and posts, and network analysis of the overlap in user populations between individual songs, to measure the affinity between songs and develop a framework for making automatic song recommendations to users as they engage with SoundCloud content. The project will provide new insights into a relevant and new business model and therefore have a substantial impact on research in both digital media studies and information systems as well as on practice.
