Abstract

To be able to support context-awareness in an Ambient Intelligent (AmI) environment, one needs a way to model context. Previous research shows that a good way to model context is using Description Logics (DL). Since context data is often coming from sensors and therefore exhibits uncertain character, it is essential to take this uncertainty into account when exploiting and reasoning about context data. In this paper, we provide an event-based probabilistic method to model context uncertainty. Each context can be viewed as a probabilistic event, which can be either a basic or complex event. We show how to deal with correlations of events (i.e., inclusion, identicalness, disjunction, and independence) which are inherent in context data and investigate their in uences on the context uncertainty.
