9th Workshop on Formal and Cognitive Reasoning (FCR-2023)

https://www.fernuni-hagen.de/wbs/fcr2023.html

Location: Berlin, Germany Deadline: July 21, 2023 Workshop: September 26, 2023

Co-located with the 46th German Conference on Artificial Intelligence (KI 2023) ========================================

Aims and Scope -------------- In real-life AI applications, information is usually pervaded by uncertainty and subject to change, and thus requires non-classical systems. At the same time, psychological findings indicate that human reasoning cannot be completely described by classical logical systems. Sources of explanations are incomplete knowledge, incorrect beliefs, or inconsistencies. A wide range of reasoning mechanisms has to be considered, such as analogical or defeasible reasoning, possibly in combination with machine learning methods. The field of knowledge representation and reasoning offers a rich palette of methods for uncertain reasoning both to describe human reasoning and to model AI approaches.

The aim of this series of workshops is to address recent challenges and to present novel approaches to uncertain reasoning and belief change in their broad senses, and in particular provide a forum for research work linking different paradigms of reasoning. A special focus is on papers that provide a base for connecting formal-logical models of knowledge representation and cognitive models of reasoning and learning, addressing formal and experimental or heuristic issues. Previous events of the Workshop on "Formal and Cognitive Reasoning" and joint workshops took place in Dresden (2015), Bremen (2016), Dortmund (2017), Berlin (2018), Kassel (2019), Bamberg (2020, online), Berlin (2021, online), and Trier (2022, online).

We welcome papers on the following and any related topics:

Action and change Agents and multiagent systems Analogical reasoning Argumentation theories Belief change and belief merging Cognitive modeling and empirical data Common sense and defeasible reasoning Computational thinking Decision theory and preferences Inductive reasoning and cognition Knowledge representation in theory and practice Learning and knowledge discovery in data Nonmonotonic and uncertain reasoning Ontologies and description logics Probabilistic approaches of reasoning Syllogistic reasoning
