Constrained consequence

Author: Britz, K ; Heidema, J ; Varzinczak, I Date: Sep 2011 There are various contexts in which it is not pertinent to generate and attend to all the classical consequences of a given premiss—or to trace all the premisses which classically entail a given consequence. Such contexts may involve limited ... Read more
From KLM-style conditionals to defeasible modalities, and back

Author: Britz, K ; Varzinczak, I Date: Mar 2018 We investigate an aspect of defeasibility that has somewhat been overlooked by the nonmonotonic reasoning community, namely that of defeasible modes of reasoning. These aim to formalise defeasibility of the traditional notion of necessity in ... Read more
Normal modal preferential consequence

Author: Britz, K ; Meyer, T ; Varzinczak, I Date: Dec 2012 One of the most successful approaches to the formalization of commonsense reasoning is the work by Lehmann and colleagues, known as the KLM approach, in which defeasible consequence relations with a preferential semantics are studied. In spite ... Read more
On stochastic belief revision and update and their combination

Author: Rens, G Date: Apr 2016 I propose a framework for an agent to change its probabilistic beliefs when a new piece of propositional information a is observed. Traditionally, belief change occurs by either a revision process or by an update process, depending on whether ... Read more
Preferential accessibility and preferred worlds

Author: Britz, K ; Varzinczak, I Date: Jun 2018 Modal accounts of normality in non-monotonic reasoning traditionally have an underlying semantics based on a notion of preference amongst worlds. In this paper, we motivate and investigate an alternative semantics, based on ordered accessibility ... Read more
Preferential reasoning for modal logics

Author: Britz, K ; Meyer, T ; Varzinczak, I Date: Nov 2011 Modal logic is the foundation for a versatile and well-established class of knowledge representation formalisms in artificial intelligence. Enriching modal logics with non-monotonic reasoning capabilities such as preferential reasoning as ... Read more
