Abstract :
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.
