The project Augmented Deliberative Democracy (ADD-up): Enhancing Large-scale Public Arbitrations in Real Time is funded 04/2017 – 12/2021 by the Volkswagen Foundation. ADD-up promotes interdisciplinary research in the field of computational social science. Principal investigators are Dr. Annette Hautli-Janisz (General and Computational Linguistics), Dr. Brian Plüss (Argumentation Mining and Visualization), and Dr. Valentin Gold (Political Science).

The aim of this project is to capitalize on the increasing digitalisation of society for advancing techniques of participatory democracy. For instance, analyses of sport events broadcast on TV (e.g. football games) are presented to the viewer by way of augmented reality, a technique which is used to enhance the experience of the viewer with computer-supplied data. The aim of the present project is to automatically monitor and enhance large-scale participatory processes in a similar way. Through an interdisciplinary collaboration between Political Science (University of Göttingen, Germany), Linguistics (University of Konstanz, Germany) and Computer Science (University of Dundee, Scotland), we will develop ADD-up, an innovative system for Augmented Deliberative Democracy (ADD).

In collaborative work with VALIDA, we have set up a first prototype for streaming communications in real-time. Some of our current ideas and potentials are demonstrated (in German) at


The VisArgue project was an interdisciplinary collaboration of political science, linguistics and information science at the University of Konstanz (principal investigators: Prof. Miriam Butt, PhDProf. Dr. Katharina Holzinger and Prof. Dr. Daniel Keim), funded by the eHumanities initiative of the German Federal Ministry of Education and Research (BMBF) from 2012 to 2016. Its main goal was the development of an automated measurement tool for the quality of deliberative communication in political discourse

In the project we used an innovative combination of methods from different areas of research, including

  • a theoretical tenet of deliberative communication originating from political science,
  • an automatic and linguistically-motivated annotation of discourse patterns relevant in deliberative communication
  • a shallow, statistical analysis of the discourse to detect common patterns in negotiations and
  • the development and employment of visualization tools to identify patterns of communication at-a-glance
