February 2019PROCO Chair publishes EJIS article on the influence of social bots on opinion perception in social media

In a forthcoming issue of the European Journal of Information Systems (EJIS), Prof. Stieglitz's chair has publishes an article examining how social bots can influence public opinion. The underlying assumption is that they influence users' tendency to express their own opinions by encouraging a spiral of silence. 

Social bots, automated accounts in social media, are said to influence the opinion-forming process of social media users. For this reason, they recently received increased attention from both the media and research. However, such an influence on opinion formation has not yet been specifically observed, partly due to methodological difficulties. 

The paper, titled „Are social bots a real threat? An agent-based model of the spiral of silence to analyse the impact of manipulative actors in social networks” therefore uses a methodologically innovative approach - with the help of a simulation (using agent-based models) the team investigates the potential of social bots to trigger a spiral of silence. The results show that under certain conditions even a small number of 4% bots in a network can change the climate of opinion in their favour.
 
The article is the result of a collaboration between participants of the Research Training Group "User-Centred Social Media" at the University of Duisburg-Essen, in which Prof. Stieglitz is Principal Investigator.

January 2019EU funds international research project "RISE_SMA”

Coordinated by the PROCO Chair at the University of Duisburg-Essen, the new research project "RISE_SMA - Social Media Analytics for Society and Crises" deals with opportunities and risks of social media. RISE_SMA aims to improve data analysis methods in order to filter relevant information from social media and process it in a meaningful way. To achieve these goals, nine partner institutions in Europe, Australia, Latin America and Southeast Asia are working together within the project.

The interdisciplinary network is funded by the EU with approx.1.2 million euros until 2022. It consists of selected top researchers, technology companies and political actors and includes the universities of Leiden (Netherlands), Agder (Norway), Sydney and Queensland (TU/Australia), UNISINOS (Brazil) and Padjadjaran (Indonesia) as well as the software developer Virtimo in Berlin and the municipality of Kristiansand (Norway).

RISE_SMA aims to take into account the increased social importance of various social media channels. In addition to the role and extent to which these are used by private, political, economic and scientific actors to disseminate information and messages, the role as an information medium, e.g. in natural disasters or attempts to find missing people, is also being investigated.

Prof. Stieglitz comments: “Apart from the technical requirements, it is of primary importance from an ethical and data-protection perspective that this data is handled responsibly.” This means that individuals, relief organizations and political stakeholders should benefit from a higher transparency enabling them to make better decisions – for example, in connection with elections or rescue missions.
