Mental models and nonmonotonic reasoning
Johnson-Laird & Byrne (J-L & B) are equivocal concerning the scope of mental-model theory. On the one hand, they are careful to note that mental models are aimed primarily at explaining deduction, although commonsense inference is not deductive in character. On the other hand, they contend that mental-model theory solves the problem of nonmonotonic reasoning, which is not deductive and is chara...
متن کاملNonmonotonic Reasoning, Preferential Models and Cumulative Logics
Many systems that exhibit nonmonotonic behavior have been described and studied already in the literature. The general notion of nonmonotonic reasoning, though, has almost always been described only negatively, by the property it does not enjoy, i.e. monotonicity. We study here general patterns of nonmonotonic reasoning and try to isolate properties that could help us map the field of nonmonoto...
متن کاملNonmonotonic Reasoning
In this talk I will give an overview of nonmonotonic reasoning as background, and then address the question of its relevance and importance for theoretical issues in reasoning about knowledge and belief. In the past few years the area. of nonmonotonic reasoning has grown tremendously, as witnessed by the increase in submitted and accepted papers to conferences such as this one. It would be impo...
متن کاملNonmonotonic Reasoning
The purpose of this paper is to expand the syntax and semantics of logic programs and deductive databases to allow for the correct representation of incomplete information in the presence of multiple extensions. The language of logic programs with classical negation, epistemic disjunction, and negation by failure is further expanded by a new modal operator K (where for the set of rules T and fo...
متن کاملNonmonotonic Reasoning
Commonsense reasoning is different. We often draw plausible conclusions based on the assumption that the world in which we function and about which we reason is normal and as expected. This is far from being irrational. To the contrary, it is the best we can do in situations in which we have only incomplete information. However, as unexpected as it may be, it can happen that our normality assum...
