Nonmonotonic Reasoning in Multivalued Logics
Inference in classical logic is monotonic: if a conclusion can be derived from a set of premises, then no additional premises will ever invalidate this conclusion. However, commonsense reasoning has a nonmonotonic component. Human beings draw sensible conclusions from what they know, making default assumptions where needed. And if there is new information, we might reconsider previous conclusio...
متن کاملThe Rationality and Decidability of Fuzzy Implications
It is well known that knowledge-based systems would be more robust and smarter if they can deal with the inconsistent, incomplete or imprecise knowledge, which has been referred to as common sense knowledge. In this paper, we discuss fuzzy implications in the sense of common sense reasoning. F i rs t ly , we analyse the ra t i ona l i t y of some exist ing fuzzy implications based on the discus...
متن کاملNonmonotonic Reasoning and Multiple Belief Revision
The aim of the present paper is to reveal the interrelation between general patterns of nonmonotonic reasoning and multiple belief revision. For this purpose we de ne a nonmonotonic inference frame in which individual inference rules have been proposed in the literature but their combination as a system has not been investigated. It is shown that such a system is so strong that almost all the r...
متن کاملAgainst Nonmonotonic Logic (DRAFT)
The monotonicity property of inference in conventional formal systems of logic (S ` A and S ⊆ T implies T ` A) appears to prohibit certain crucial steps in practical intuitive reasoning. For example, reasoning by default (using assertions that are assumed to hold until explicitly contradicted) appears to be impossible in monotonic systems. Many crucial steps in practical reasoning certainly req...
متن کاملOn natural deduction system for nonmonotonic reasoning
This paper is concerned with the problem of how to construct a natural deduction system for nonmonotonic reasoning. Three possible constructions are investigated, the ones which consists of (1) pure nonmonotonic inference rules; (2) nonmonotonic inference rules plus a nonmonotonic tautology base; or (3) nonmonotonic inference rules plus a nonmonotonic conditional assertion base. Based on a fram...
