Announcement

Dear Researchers and Practitioners in Computational Social Science (CSS),

We invite you to our upcoming conference on Democracy at Risk? Societal Challenges, Data, and Research Infrastructures in the Age of CSS in Vienna, organized by Complexity Science Hub and Central European University. This two-day, in-person conference is part of an annual event series that connects Computational Social Science (CSS) scholars from the German-speaking region (Austria, Germany, and Switzerland). As an interdisciplinary event, it addresses researchers from a range of disciplines, including sociology, political science, computer science, communication, economics, digital humanities, and data science. The conference provides a platform for networking, professional development, and the exchange of ideas in CSS.

This year’s event will focus on CSS and threats to democracy. Around the world, democracies are increasingly under pressure from both domestic and foreign actors. CSS offers valuable tools to study these developments — for instance, by enabling access to new data sources to investigate digital disinformation or by identifying anti-authoritarian campaigns through network analysis. However, the field itself also faces challenges, including limited access to critical data and growing dependence on opaque tools and infrastructures controlled by big tech companies.

The conference will address both methodological and practical questions related to studying (digital) democracy using CSS, including (but not limited to) the following questions:

Using CSS to study (threats to) democracy (e.g., theoretical and empirical work on identifying digital campaigns via network analysis; the role of big tech in shaping public opinion; studying the erosion of and improving the resilience of democratic institutions and discourses; using digital trace data to understand citizens’ exposure to political content)
Obstacles to the analytical potential of CSS (e.g., the impact of insufficient data access and methodological limitations on early-career researchers; risks posed by black-box generative AI tools; legal issues in CSS; disparities in access to computational infrastructure; platform governance and transparency)
Advancing the independence of CSS data access, tools, and infrastructures (e.g., developing tools for accessing new data sources; promoting open-source alternatives; creating infrastructures independent of big tech; implementing regulatory frameworks like the Digital Services Act or the AI Act; tackling legal ambiguities and researcher risks; supporting CSS researchers)

What to expect

Invited Talks: Hear from leading scholars who will share insights on conceptual challenges, methodologies, and empirical applications in CSS.
Panel Discussion: Engage in a discussion with experts and peers on current and future trends related to CSS and democracy.
Early Career Poster Session: Are you an early career CSS researcher? Present your research with a short talk and a poster (details to follow)!
Networking Opportunities: Connect with fellow researchers and professionals to build a robust CSS community in the DACH area.

Who Should Attend? This event is for academics, researchers, and professionals involved in CSS or interested in applying computational methods in social science research. Whether you are an experienced scholar or a young researcher in this field, your contributions and participation will be highly valued.

Note: As the conference features invited talks and sessions aimed at academic exchange, you do not have to submit your research to participate (unless you want to present in the early career track).

We look forward to welcoming you to an engaging and inspiring event!

Call for Early Career Researcher Contributions

We invite early career researchers (Master students, PhD students or PostDocs) to submit and present their CSS-related work at the DACH-CSS conference. Please submit an abstract of up to 300 words to workshop@computational-social-science.org by February 20, 2026. Another way to submit your work is by uploading the abstract during the registration process. Accepted contributors will give a short lightning talk (2 minutes) and present their work in greater detail during the poster session. We offer a limited amount of presentation slots, and submissions will be selected based on fit with CSS and this year’s conference theme, as well as the originality and quality of the work. Acceptance notifications will be sent out in March 2026. Please note that you will still have to buy a regular conference ticket.

As part of the event, we will confer a CSS Early Career Researcher Award (worth 500 EUR). All accepted submissions are automatically eligible. In addition to the conference’s core theme, Democracy at Risk? Societal Challenges, Data, and Research Infrastructures in the Age of CSS, we welcome submissions on topics including, but not limited to:

Best-practice applications of computational methods/big data to (complex) social science research questions
Work that combines established social science theories with digital data or/and computational methods
Empirical results and research designs from ongoing or completed CSS projects
Theoretical and conceptual challenges in CSS
CSS methodological innovations; including mixed-methods approaches
Data linkage applications and methods for enriching large-scale or online data sources

Please note that submission acceptance and conference registration are handled seperately. You are welcome to attend the conference regardless of whether your submission was accepted. If your submission was accepted, you will still need to register for the conference.

Conference Registration

The conference welcomes researchers from all career levels to partake in discussing directions of CSS research and networking with other CSS scholars. Slots will be allocated on a first-come, first-served basis.

Registration as Participant

Registration is currently closed because all tickets have been sold out. In case someone returns their ticket, it will be available for sale at the page linked below
