CLAR 2023 The 5th International Conference on Logic and Argumentation
10th - 12th September 2023 Hangzhou (China)

ANNOUNCEMENT: Due to a low number of submissions, we announce a deadline extension for CLAR 2023. The new deadline is May 6th. (Please see all dates below.) The conference will by organised in hybrid mode, with all online talks scheduled in the same session or day.

The 5th International Conference on Logic and Argumentation (CLAR 2023) invites contributions from logic, artificial intelligence, philosophy, computer science, linguistics, law, and other areas studying logic and formal argumentation. CLAR 2023 will be held 10th-12th September 2023 at Zhejiang University in Hangzhou. In order to save travelling cost and time, the conference will be held in a HYBRID format (virtual and physical attendance both accepted), and we encourage physical participation if possible.

CLAR 2023 aims to highlight recent advances in logic and argumentation and foster interaction in these two areas between researchers within and outside China.

The interplay between logic and argumentation spans different disciplines and historical eras: from ancient philosophy (Socrates' dialectics, Aristotle's logic) to contemporary computer science (dialogues, multiagent systems). Research in logic and argumentation offers formal or semi-formal models that capture reasoning patterns and dialogue activities of diverse kinds. Their applications in artificial intelligence range from law and ethics to linguistics. CLAR 2023 will focus on a variety of topics and formalisms, including formal models of argumentation (abstract or structured), preference and support, but also dispute and dialogue systems for online argumentation or the processing of legal texts.

Established in 2016 as a workshop hosted by Zhejiang University, the CLAR series has been increasingly successful and become an international event and discussion forum in the two areas of logic and argumentation. Our aim for CLAR 2023 is to be a platform for the advancement of the existing discussions within each of the areas above, to span bridges between their different traditions, and finally to open argumentation to new applications and other areas in artificial intelligence, such as legal reasoning, explainable AI, ethical dilemmas, reasoning about uncertainty and knowledge representation, etc. Previous conferences can be accessed via:

CLAR 2023 will be financially supported by a national key project called "Research on Logics for New Generation Artificial Intelligence" (2021-2025), granted by the National Social Science Foundation of China. More information about the project:
