Non Monotonic Reasoning and Belief
The major approaches to belief revision and non monotonic reasoning proposed in the literature diier along a number of dimensions, including whether they are \syntax-based" or \semantic-based", \foundational" or \coherentist", \consistence{restoring" or \inconsistency{tolerant". Our contribution towards clarifying the connections between these various approaches is threefold: We show that the t...
متن کاملNon-monotonic Reasoning and the Reversibility of Belief Change
Traditional approaches to non-monotonic reasoning fail to satisfy a number of plausible axioms for belief revision and suffer from conceptual difficulties as well. Recent work on ranked preferential models (RPMs) promises to overcome some of these difficulties. Here we show that RPMs are not adequate to handle iterated belief change. Specifically, we show that RPMs do not always allow for the r...
متن کاملDescribing Plan Recognition as Nonmonotonic Reasoning and Belief Revision
We provide a characterization of plan recognition in terms of a general framework of belief revision and non-monotonic reasoning. We adopt a generalization of classical belief revision to describe a competence model of plan recognition which supports dynamic change to all aspects of a plan recognition knowledge base, including background knowledge, action descriptions and their relationship to ...
متن کاملOn the Relation between the Coherence and Foundations Theories of Belief Revision
Two recent papers, (GG ardenfors 1990; Doyle 1992), try to assess the relative merits of the two main approaches to belief revision, the foundations and coherence theories, but leave open the question of the mathematical connections between them. We answer this question by showing that the foundations and coherence theories of belief revision are mathematically equivalent. The result also has c...
