Reasoning with Partial Knowledge
We investigate how sociological argumentation di ers from the classical rstorder logic. We focus on theories about age dependence of organizational mortality. The overall pattern of argument does not comply with the classical monotonicity principle: adding premises does not overturn conclusions in an argument. The cause of nonmonotonicity is the need to derive conclusions from partial knowledge...
متن کاملReasoning With Uncertain Knowledge
Heuristics derived from human experimentation are integrated with a knowledge network to pro duce a model for reasoning with uncertain information. The believability of knowledge is deter mined by collecting reasons for believing and not believing it. These reasons, or endorsements, are subsequently ordered by their belief, the reliability of their belief, and their importance relative to one...
متن کاملDiagnostic Reasoning with Anaesthesia Knowledge
This paper reports on a collaboration between two research groups. The first group has studied Formalization of ANaesthesia knowledge (FAN). An aim in the knowledge formalization was support of diagnosis, but the diagnostic method to be used was itself not formalized at the time. The second group has developed a general framework for diagnostic reasoning. The framework is parametrized to accoun...
متن کاملReasoning with Higher Order Partial Functions
In this paper we introduce the logic P HOL, which embodies higher-order functions through a simply-typed-calculus and deals with partial objects by using partially ordered domains and three truth values. We deene a refutationally complete tableaux method for P HOL and we show how to derive a sound and complete cut free sequent calculus through a systematic analysis of the rules for tableaux con...
متن کاملPartial logics with two kinds of negation as a foundation for knowledge - based reasoning
REPORTRAPPORT Partial logics with two kinds of negation as a foundation for knowledge-based reasoning Abstract We show how to use model classes of partial logic to deene semantics of general knowledge-based reasoning. Its essential beneet is that partial logics allow us to distinguish two sorts of negative information: the absence of information and the explicit rejection or falsiication of inf...
