June 2020Journal of Information Technology (JIT) publishes articles on the use of social media in crisis situations like COVID-19

Stefan Stieglitz and Julian Marx from the PROCO Chair, Milad Mirbabaie from the University of Bremen and Deborah Bunker and Christian Ehnis from the University of Sydney have published an Open Access article in the Journal of Information Technology (JIT). The article examines which factors determine the influence of actors in social media communication on crisis situations. For this purpose, roughly 9.5 million tweets about Hurricane Harvey were analyzed to determine which factors are most likely to influence the entire conversation through the messages of individual actors (e.g. organizations such as the WHO, politicians or the media).

The results show that on the one hand the so-called Topical Authority and Topical Frequency of the actors determine their reach and influence, on the other hand a high value of message content or the distribution by popular actors. The results are discussed in the context of the COVID19 pandemic to show how they can provide a positive added value here.

The paper is part of the EU-funded RISE_SMA project, which promotes the international and interdisciplinary exchange of scientists and is coordinated by the PROCO chair.

April 2020Prof. Stieglitz supervises AJIS-Special Section on Ethics in Social Media Research in (Call for Papers)

 

Together with Prof. Deborah Bunker (University of Sydney Business School) and Dr Shirlee-ann Knight (Curtin University Perth), Prof. Stieglitz is supervising a special section on research on applied ethics in the Australasian Journal of Information Systems (AJIS).
 
We are looking for contributions that deal with ethics in social media research. Since social media data is often used for research and conclusions are drawn from it, it is important to deal with possible consequences. This includes, for example, conclusions for an entire population based on the data, whereby the data only reflects the part of the population that uses social media. These and other aspects will be discussed in the special section from an ethical point of view.
 
Prof. Stieglitz calls for papers on the above mentioned topic. The deadline ends on 21.09.2020. Further information can be found in the linked PDF file.

March 2020Postponement 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. 

Examinations

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.

More information can be found here.

We hope that these measures will ensure the best possible protection for all members of the UDE and slow down the spread of the virus. At the same time, we would like to point out once again that each and every individual can make a significant contribution to their own protection and that of others by observing hygiene measures and reducing social contacts.

January 2020Chair receives DAAD funding for project with University of Wollongong in Australia

The chair of Prof. Dr. Stieglitz has been granted project funding within the framework of  the German Academic Exchange Services (DAAD) program of project-related person exchange (PPP). The provided funds enable young researchers of the chair to visit the University of Wollongong in New South Wales, south of Sydney. The project is carried out in cooperation with Prof. Rodney Clarke and investigates social media discussions that occur during enterprise crises. The aim is to better analyse and understand these discussions by gaining new insights about the users involved. The project runs over 2 years until the end of 2021.

May 2019Chair publishes report on Twitter Communication and the 2019 European Parliament Election

Over a period of one and a half months, the Chair collected and evaluated 643,182 tweets from 168,948 authors related to the EU election. All tweets in English and German written between April 1, 2019 and May 17, 2019 and containing one of the following hashtags were tracked: #EUElections2019, #EP2019, #Europawahl2019, #EUElections, #EUElection, #Europawahl, #EUWahl, #EUW19, #EP2019, #EE2019. 

The data was evaluated against various criteria such as account visibility and activity as well as tweet visibility. In addition, relationships between different accounts were visualized using social network analyses.

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.
