Nowadays the combination of virtually free computation and ubiquitous environment has formed the new domain of pervasive computing. Context reasoning part in the context awareness seems to become one of the most important goals of that computing trend. Our approach comes from the behaviors of the context which depends on various aspects of the surrounding contexts. In this paper, we present a novel approach to model and reason context based on contextual graphs. We introduce the contextual graph in details and the context reasoning process for supporting ubiquitous computing. The contextual graph is expected to make it easier for developers to develop various applications with the need of context reasoning.
