Postponement of courses and start of lectures

Due to the progressive spread of the novel corona virus, we are suspending our courses and examinations until 19.04.2020.

Lectures and courses of the summer semester 2020

In agreement with the Ministry of Culture and Science NRW (MKW NRW), the Rectorate has decided to postpone the start of the semester to 20 April 2020. This means that teaching in classroom form will be completely discontinued by then. This applies to courses, exercises, tutorials, seminars, laboratory practicals and, if applicable, other forms of events. 


All planned examinations, including e-examinations, from Monday, 16 March 2020 onwards are initially cancelled. We will make every effort to create secure conditions for the exams so that they can be made up for by 20 April 2020.

PROCO 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.

EU 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.

DFG is funding a project on research data management at the University of Duisburg-Essen

Together with the WWU Münster, Prof. Dr. Stefan Stieglitz receives funding from the German Research Foundation (DFG) for the implementation of the project "sciebo Research Data Services - Research Data Management Services and Tools for Scientists". The aim is to implement particularly low-threshold services for the management of research data. Ideally, this scientific research data should be stored in a sustainable and transparent way. In order to make this additional work easier for researchers, services and tools will be developed over a period of three years. These tolls will support research data management from project development and operational work with the data in the research project through to the publication and archiving of research data. These services and tools will be technically embedded in the collaboration and storage service "sciebo", which now has approximately 115,000 users. The project is conducted in cooperation with Dr. Beate Tröger from the University and State Library (ULB) Münster and Dr. Raimund Vogl from the Centre for Information Processing (ZIV) of the WWU Münster.

Chair receives best paper award at HICSS 2018

The paper "The Diffusion of Crisis-Related Communication on Social Media: An Empirical Analysis of Facebook Reactions" received the best paper award at the 51st Hawaii International Conference on Systemic Sciences (HICSS). It was written by Björn Ross, Tobias Potthoff and Prof. Stefan Stieglitz at the PROCO Chair and emerged from a cooperation in course of a DAAD project with the University of Agder in Norway.

In the context of crisis communication, the article examines the relationship of various parameters of Facebook posts (such as text length or use of images) with the response to these posts (e.g., the frequency of sharing or expressing emotional responses). The authors show that pictures and videos in articles have a positive influence on the number of reactions to the post, while text length has a negative influence on the frequency with which a post is shared.

Social Media Chair launches website on the Twitter communication surrounding the 2017 Bundestag election.

The department "Professional Communication in Electronic Media / Social Media" (PROCO) has launched a website on which public Twitter communication in the run-up to the federal election in 2017 is presented.

Based on various hashtags (e. g. #btw2017 or #bundestagswahl [German for Bundestags election]) and accounts (@MartinSchulz or @CDU) tweets have been collected since July 11,2017 and prepared in several graphics on the website. As the increasing use of social media for political communication also increases the amount of data produced as well as its significance, the website is intended to show how often the Bundestag elections, parties and politicians are discussed on Twitter in the Bundestags election campaign of 2017.

With the help of the graphics, parameters such as the visibility of the parties or the number of tweets for the Bundestag election can be fast assessed visually. In addition, individual aspects are addressed and analysed in more detail. The analyses are part of the DFG project "Topic careers in internet publicity", which is carried out jointly between the University of Duisburg-Essen (Prof. Dr. Stefan Stieglitz) and the LMU Munich (Prof. Dr. Christoph Neuberger).
