The Second International Workshop on Argumentation and Applications
Melbourne, Australia, November 2025 - Collocated with KR 2025

Formal models of argumentation have received much attention of late, in particular from the Knowledge Representation and Reasoning (KR) community. This has resulted in various applications of argumentation (cyber-democracy, law, medicine, public policy making, sustainable development, etc.), which benefit from the advances on the theoretical aspects of argumentation, while highlighting new theoretical issues. Further, applications of argumentation often branch into other areas of AI, demonstrating argumentation’s potential in areas such as machine learning, multi-agent systems and explainable AI.
Arg&App seeks to bring together researchers working on the definition and evaluation of methods in these applications, as well as the development of software therefor, which has often been deployed in real-world contexts. The first edition of the Arg&App workshop took place in Rhodes (2023), in collocation with KR 2023.
The workshop specifically welcomes (possibly preliminary or incremental) works covering:
- Novel applications of argumentation-based methods
- Experimental evaluation methods for argument-based applications
- User-oriented evaluation and empirical testing of argument-based applications
- Design principles and software engineering aspects of tools for formal argumentation
- Benchmark generation and empirical studies on real-world argumentation graphs
- System descriptions of tools for formal argumentation
Software descriptions are also welcome. Time will be given to demonstration of applications.
The workshop proceedings will be published as CEUR Workshop Proceedings.
We are happy to announce that Prof. Beishui Liao will give a talk at Arg&App 2025.
