Visualization of Argumentation Networks

The field of computational argumentation has seen substantial progress in recent years. Computational argumentation helps in shaping civil online public spheres by illustrating and promoting diverse views, and thus aligns well with the principles of digital humanism. However, these aims require systems that allow users to visualize argumentation scenarios and solutions and that provide powerful interaction mechanisms. In this project, we (i) adapt and extend existing argumentation formalisms to allow for advanced user interfaces, (ii) develop layout objectives that ensure stability over time in dynamic settings and investigate interaction techniques that respect the mental map of users, and (iii) apply state-of-the-art techniques from visual data analysis to address scalability and explainability. We expect applications in mediation processes and analyses of multi-party discourses.
