Reasoning about uncertain contexts in pervasive computing environments
2004
IEEE pervasive computing
Our model represents any piece of information whose truth value is potentially uncertain as a predicate. Context-aware systems can't always identify the current context precisely, so they need support for handling uncertainty. A prototype pervasive computing infrastructure, Gaia, allows applications and services to reason about uncertainty using mechanisms such as probabilistic logic, fuzzy logic, and Bayesian networks.
