Logical approaches to uncertainty and vagueness in the view of thecontext model

摘要

The context model provides a framework for clear semantics ofconcepts for handling uncertainty and vagueness. The authors analyzenon-truth-functional logics with capabilities for the representation ofuncertainty and vagueness in the view of the context model. It becomesapparent that among other approaches probabilistic and possibilisticlogic can be considered as logics with additional restrictions in thegeneral environment of the context model. Due to the semantic backgroundof the context model it is possible to clarify and interpret the meaningof concepts like revision and expansion, and to describe the generalassumptions used in various approaches
