About us

The Sixth International Workshop on Logics and Argumentation for New-Generation Artificial Intelligence (LNGAI 2026) focuses on the interaction between symbolic and subsymbolic forms of argumentation reasoning in agentic AI systems. It studies how subsymbolic models like neural and large language models can generate or support argumentation, and how formal and computational argumentation can analyze and verify reasoning produced by learning-based models. It specifically highlights hybrid and neuro-symbolic approaches for reliable and interpretable AI.
