Rational Defeasible Reasoning for Description Logics [PDF]
, 2018 In this paper, we extend description logics (DLs) with non-monotonic reasoning fea- tures. We start by investigating a notion of defeasible subsumption in the spirit of defeasible conditionals as studied by Kraus and colleagues in the propositional case.

A defeasible reasoning approach for description logic ontologies
, 2012 National audienceClassical reasoning for logic-based KR (Knowledge Representation) systems is in general, monotonic. That is, there is an assumption in these systems that there is complete information about a domain. This means that they generally cannot

A Family of Defeasible Reasoning Logics and its Implementation [PDF]
, 2000 Defeasible reasoning is a direction in nonmonotonic reasoning that is based on the use of rules that may be defeated by other rules. It is a simple, but often more efficient approach than other nonmonotonic reasoning systems. This paper presents a family

Toward a “strong” normativity of fear in Hans Jonas and Aristotle
The Southern Journal of Philosophy, EarlyView.Abstract What does it mean to say that one “ought” to undergo an emotion? In The Imperative of Responsibility, Hans Jonas provocatively asserts that twentieth‐century citizens “ought” to fear for the well‐being of future generations. I argue that Jonas's demand is not straightforwardly reducible to claims about the fittingness, expedience, or aretaic ...

Editorial: Defeasible and Ampliative Reasoning
International Journal of Approximate Reasoning, 2019 International audience ; Classical reasoning is not flexible enough when directly applied to the formalisation of certain nuances of decision making as done by humans. These involve different kinds of reasoning such as reasoning with uncertainty, exceptions, similarity, vagueness, incomplete or contradictory information and many others.

Reasoning with Defeasible Arguments: Examples and Applications
, 1992 This paper attempts to demonstrate the wide variety of characteristic properties of defeasible argumentation, of which nonmonotonicity is one. To do so, we introduce a simple formalism, called abstract argumentation system, with which we discuss ...

Topics in Cognitive Science, EarlyView.Abstract Our ability to imagine alternatives to reality is central to everyday cognition. Our competence in reasoning depends not only on our capacity to envisage the relevant facts, but also on our proficiency in simulating alternatives to them. I discuss how our skill in making deductive inferences depends on imagining possibilities. To illustrate, I

On a Flexible Representation for Defeasible Reasoning Variants
, 2018 International audienceWe propose Statement Graphs (SG), a new logical formalism for defeasible reasoning based on argumentation.Using a flexible labeling function, SGs can capture the variants of defeasible reasoning (ambiguity blocking or propagating ...

Journal of Contingencies and Crisis Management, Volume 34, Issue 2, June 2026.ABSTRACT This study investigates the impact of digital transformation and emerging technologies, particularly generative artificial intelligence (GenAI), on the readiness and practices of crisis communication professionals in Hong Kong (HK). Despite growing theoretical advances, recent literature remains predominantly Western‐centric, with limited ...

Alchourr'on's Defeasible Conditionals and Defeasible Reasoning
, 1997 this paper will be devoted to showing that Alchourr'on's defeasible conditionals are a cumbersome way to handle defeasibility: these conditionals hide defeasibility's essential procedural aspects, and relegate them to a mere clerical task ...
