Introduction
The 2026 edition of the ArgMining workshop therefore places a special focus on understanding and evaluating arguments in both human and machine reasoning. With this topic, we broaden the workshop’s focus to include reasoning, a long-standing area of research in AI that has recently gained renewed interest within the *ACL community, driven by the latest generation of LLMs. Reasoning is tightly connected to argumentation as it represents, analyzes and evaluates the process of reaching conclusions on the basis of available information. If we consider argumentation as a paradigm to capture reasoning, then machines (particularly LLMs) can be evaluated based on their ability to address argument mining tasks.
The workshop will be co-located with ACL 2026 and held in San Diego, United States in a hybrid format.
