September 3rd-4th, 2019Main symposium


This is the third in a series of three symposia that discuss societal challenges in computational social sciences. In 2019, the focus will be on “Polarization and Radicalization” (Zurich, 2019). In the previous two years, the focus was “Inequality and Imbalance” (London, 2017) and “Bias and Discrimination” (Cologne, 2018).

With these three events we provide a platform to address one of the most pressing challenges in today’s digital society: understanding the role that digital technologies, the Web, and the algorithms used therein play in the mediation and creation of inequalities, discrimination and polarization.

By addressing inequality as the topical issue for the symposium series we intend to explore how CSS can contribute to opening up new ways of thinking about, of measuring, detecting and coping with social inequality, discrimination, and polarization. We will discuss how divides and inequalities are proliferated in digital society, how social cleavages can be observed via web data, how the organizational structure of the web itself generates biases and inequality, and how, in contrast, algorithms and computational tools might help to reduce discrimination and inequality. We will also investigate how bias and unequal social structures foster political tension and polarization, including issues of radicalization and hate.

The Symposium series is funded by the Volkswagen Foundation.



The Euro CSS 2019 will be a three-day event consisting of:

  • a two-day, single-track conference featuring a series of invited talks that will provide different perspectives on challenges in the area of Polarization and Radicalization
  • a day of multiple satellite events, including workshops and tutorials
  • an open call for contributed presentations that will provide opportunities for computational social scientists to present and discuss their own work
  • an open call for workshop and tutorial organization that will provide opportunities for computational social scientists to gather focus groups around the latest trends in computational social science
  • a dataset challenge to encourage creative engagement with the data from different perspectives and dialogue across disciplines
  • plenty of possibilities for interdisciplinary networking (e.g. science slam)


You can register online via Eventbrite (click here) until August 17th, 2019. Paper/poster submission is not a requirement for attendance.

The registration fee is 60 CHF. It covers the participation fee, coffee breaks and lunch (September 2nd-4th, 2019). To secure a place for a workshop or tutorial on the first day, don’t forget to register early.

Call for Abstracts

We welcome submissions in the intersection of the social sciences and the computer sciences, including (a) new approaches for understanding social phenomena and addressing societal challenges, (b) improving methods for computational social science, (c) and understanding the influence of the Web and digital technologies on society.

For the 3rd Symposium we are especially interested in the following four main topics:

I. misinformation and censorship
(including political tension, upheaval and disrupt; public sphere in the digital age; social media as alternative communication channels; information leakage; whistleblowing)

II. discourse polarization and echo chambers
(including discourse radicalization; effects of filter bubbles; online and offline radicalization; diffusion of information)

III. online and offline group formation
(including global, national and local network structures; effects of weak and strong ties in contemporary and historic societies; mobilization patterns)

IV. political polarization and populism
(including political networks and party politics; detection of radicalization and deradicalization; political campaigning)

Important Dates:

Submission deadline: April 20th, 2019
Acceptance notification: June 10th, 2019
Conference days: September 3rd and 4th, 2019

Submission Guidelines:

Extended abstracts should be submitted in English and in pdf format [here]

Submissions should be abstracts of approx. 2-3 pages (up to 1000 words plus references and figures) summarizing the work to be presented. We encourage researchers to also submit abstracts of work that has already been published and/or submit work in progress. Please give a sufficiently detailed description of your work and your methods so we can adequately assess its relevance. Please consider that reviewers will be from an interdisciplinary community.

Each extended abstract will be reviewed by a Program Committee composed of experts in computational social science. Accepted submissions will be non-archival, i.e. there are no proceedings. Submissions will mostly be evaluated based on relevance and the potential to stimulate interesting discussions. Submissions may be accepted as talks or posters and there will be the SAGE Best Presentation Award as well as the EPJ Data Science Best Poster Award.



Call for Workshop and Tutorials

Workshops will give the opportunity to meet and discuss issues with a selected focus, providing an excellent forum for exploring emerging approaches and task areas and bridging the gaps between the social science and technology fields.

Tutorials will be an opportunity for cross-disciplinary engagement and a deeper understanding of new tools, techniques, and research methodologies. Tutorials should provide either an in-depth look at an emerging technique or software package or a broad summary of an important direction in the field.

Members of all segments of the social media research community are encouraged to submit proposals. To foster interaction and exchange of ideas, the workshops will be kept small, with 30 participants maximum.

Important Dates:

Submission deadline: March 10th, 2019
Acceptance notification: March 30th, 2019
Workshops and tutorials day: September 2nd, 2019

Submission Guidelines:

Please submit your workshop or tutorial proposal by sending a PDF file via email to

Proposals for workshops and tutorials should be no more than three (3) pages in length (10pt, single column, with reasonable margins), written in English, and should contain the following:

a) A concise title
b) The names, affiliations, and contact information of the organizers
c) Planned duration of the event (half-day or full-day meeting)
d) A short abstract describing the scope and main objective of the event
e) A description of the proposed event format and a detailed list of proposed activities

Workshops and tutorials will be selected based on the following criteria:

1) Timeliness of the topic
2) Potential to attract the interest of researchers in computer science and social/organizational sciences
3) Promotion of activities that are different from the classic mini-conference format; those include challenges, games, interactive sessions, brainstorming and networking.
4) Involvement people of different backgrounds in the organizing committee
5) Addressing topics at the intersection of different disciplines



This year the symposium will again feature a doctoral consortium. It will take place on the pre-symposium day September 2, 2019.
PhD candidates from all disciplines that work on topics related to computational social science are welcome to apply for participation. The doctoral consortium is non-public and will only be open to participants that have been selected based on their applications.

During the doctoral consortium, participants will receive individual feedback on their work from two experts of different areas in CSS who will join as mentors during the event. Participants will also have the opportunity to connect with other PhD candidates in the field. Participation in the doctoral consortium is most useful for doctoral candidates “in the middle” of their PhD, but in exceptional cases we might also select people who have only recently started working on their topic or are already close to finishing their PhD.

Based on the submissions we will select participants to present their work in the consortium meeting and to participate in discussions and mentoring sessions. We are interested in all topics that fit into computational social science, the topic of the PhD thesis does not have to be directly related to this year’s symposium theme “polarization and radicalization”.

Submission Guidelines

Applications should be submitted via Easychair:
Submissions should be PDF files of up to approx. 1000 words, including the following information:

  • an abstract of the PhD thesis topic including information about the research question, applied methods and the current state of progress.
  • a short paragraph about the applicant’s biography
  • a paragraph on open questions that the applicant would want to discuss with the community and experts in the field

Deadline for submissions is May 10th, 2019 extended to May 20th, 2019.

Travel Grants

Participants presenting in the doctoral consortium can also apply for travel grants. The number of grants as well as the amount per grant is limited. Please see more detailed information here.

Call for Participation: Dataset Challenge 2019 –
Machine Behavior Datathon

The European Symposium on Societal Challenges in CSS will host a one-day datathon on September 2nd, 2019 on the topic of Machine Behavior. The aim of the datathon is to advance our understanding of machine behavior, quantitatively analyzing the behavior of intelligent machines in their natural environments when interacting with humans. We are specially interested in both the behavior of machines and of humans when interacting with each other through any medium.

Topics of interest include but are not limited to:

  • Bot-human interaction on social media or other environments
  • Collaborative content editing between human and machine users
  • Algorithmic effects on opinions, emotional expression, and collective behavior
  • Learned or emergent biases and discrimination in machine behavior

Participants will have access to a series of datasets on the above topics but can also bring their own data on related topics. Please see more information about the datasets here: The datathon will start with some introductory presentations and will have leading scientists in the field as advisors to help in the projects. At the end of the day, each participant will present their work and the best project will earn a Euro CSS Dataset Challenge Award (250 EUR).

The deadline for registration to the Machine Behavior Datathon is August 17th, 2019.

Please register for the symposium via Eventbrite and make sure to select both the morning and afternoon Dataset Challenge sessions “[Full Day Event – Part I] Dataset Challenge” as well as “[Full Day Event – Part II] Dataset Challenge” in the workshop/tutorial selection menu.
