Defeasible modalities

Author: Britz, K ; Varzinczak, I Date: Jan 2013 Nonmonotonic logics are usually characterized by the presence of some notion of `conditional' that fails monotonicity. Research on nonmonotonic logics is therefore largely concerned with the defeasibility of argument forms and the associated ... 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
Modelling object typicality in description logics

Author: Britz, K ; Heidema, J ; Meyer, T Date: Dec 2009 The authors present a semantic model of typicality of concept members in description logics (DLs) that accords well with a binary, globalist cognitive model of class membership and typicality. The authors define a general preferential semantic ... Read more
Modelling object typicality in description logics - [Workshop on Description Logics]

Author: Britz, K ; Heidema, J ; Meyer, T Date: Jul 2009 The authors presents a semantic model of typicality of concept members in description logics that accords well with a binary, globalist cognitive model of class membership and typicality. The authors define a general preferential semantic ... 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 role restrictions

Author: Britz, K ; Casini, G ; Meyer, T ; Varzinczak, I Date: Jul 2013 We extend the Description Logic ALC with preferential role restrictions as class constructs, and argue that preferential universal restriction represents a defeasible version of standard universal restriction. The resulting DL is more expressive ... Read more
