First Workshop on

Challenges and Adequacy Conditions for Logics in the New Age of Artificial Intelligence



Cercedilla (Madrid), Spain
November 3-5, 2022

Aims and scope

The rapid advances of Artificial Intelligence and the widespread diffusion of AI systems today create new challenges for logics and systems of formal reasoning. Besides its traditional role as a vehicle for knowledge representation and reasoning in symbolic AI, logic should also play a pivotal role in furthering responsible and trustworthy AI through its capacity to reason about intelligent systems, analyse their behaviour and provide explanations for the results obtained and decisions and actions taken by such systems. 

If logic is to help make AI more accountable, logic itself needs to be accountable. It should therefore be susceptible to critical examination and evaluation of its adequacy for the objectives which its designers and users have set it.

This is the first workshop on challenges and adequacy conditions for logics in light of their important role in contributing to accountable AI. It is organised in the framework of the project LIANDA1, supported by the Fundación BBVA, and is co-organised by the Knowledge Representation Group of the Spanish AI Society AEPIA. The workshop will host a range of talks and discussions that include technical work on current systems of logic for AI as well as philosophical reflection on logical methodology, besides examining external desiderata for logics that arise for instance from legal or ethical requirements for AI systems.
