Defeasibility in Contextual Reasoning with CKR. [PDF]

, 2013
Recently, representation of context dependent knowledge in the Semantic Web has been recognized as a relevant issue and a number of logic based solutions have been proposed in this regard: among them, in our previous works we presented the Contextualized Knowledge Repository (CKR) framework. A CKR knowledge base has a two layered structure, modelled by

DEFEASIBLE REASONING BY USING ANALOGIES

1990
An approach for knowledge acquisition by using analogies is proposed in the paper. The additional information obtained by analogy is intended for defeasance of the significance of examples or counterexamples for the investigated proposition. The truth value of the proposition could be changed without changing truth values of any propositions connected ...

Defeasible reasoning with structured information

1994
There is a wide variety of approaches to formalising non-monotonic reasoning, and even though some relationships between formalisms have been established, there is a lack of appropriate general frameworks to support such analyses. There have been some successes such as using general properties of the consequence relation as a framework (Gabbay 1985 ...

Defeasible Reasoning and Representation

2017
The Gettier Problem exhibits how our human cognitive fallibility of representation noted by Sellars and Quine always leaves open the possibility of completely justified beliefs being false. True justified belief, Gettier showed us, may result from the deduction of a justified false belief and thus fall short of knowledge.
