TL;DR
This paper proposes a method for the measurement of uncertainty based on both physical and operational behaviors of the sensors and describes how the level of uncertainty is incorporated into different layers of a semantically driven context aware system and how it is transferred to a decision engine in order to perform more accurate decisions in ambiguous observations.
