The 3rd International Conference on Logic and Argumentation (CLAR 2020) invites interdisciplinary contributions from logic, artificial intelligence, philosophy, computer science, linguistics, law, and other areas studying logic and formal argumentation.

CLAR 2020 will be held in Hangzhou, 6-9 April 2020, as part of the International Conferences on Logic and Artificial Intelligence at Zhejiang University (ZJULogAI). With a special focus on “methods and tools for explainable AI”, a core objective of ZJULogAI is to present the latest developments and progress made on the crucial question of how to make AI more transparent, trustworthy and accountable, both in China as well as in the rest of the world. All participants to CLAR 2020 have access to all other events of ZJULogAI as well.

Online LNAI proceedings with accepted submissions will be available during the conference, and extended versions will be published after the conference in a special issue of the Journal of Logic and Computation.

Submission Guidelines

We invite two types of submissions: full papers (between 12 and 20 pages) describing original and unpublished work and extended abstracts (between 4 and 8 pages) of preliminary original work or extended abstracts of already published work, from either the field of logic or the field of formal argumentation. Additional support material may be included in an appendix, which may be considered or ignored by the program committee.

Submissions must be prepared in LaTeX, using the Springer LNCS style:


Submissions not complying with these guidelines will be desk rejected.

Papers in PDF format should be submitted via EasyChair:
