Abstract

In this work we apply a form of existential abstraction on the prominent structured approach of assumption-based argumentation (ABA) via clustering assumptions, leading to simplified argumentation scenarios supporting explainability. We present ways of interpreting clustered ABA frameworks, look at use cases, and provide an interactive automated tool that obtains faithful clusterings.
