Uncertantty in temporal representation and reasoning

Abstract

The paper presents an approach of managing temporal knowledge under imprecision or uncertainty, based on possibility theory and fuzzy logic. Temporal uncertainties are modelled in terms of possibility theory with imprecise time instants, imprecise time intervals and imprecise time durations. An integrated approach has been given for combining qualitative and quantitative temporal information using fuzzy logic.
