Linking Context Modelling and Contextual Reasoning

Abstract. In this paper, we discuss a novel perspective on ontologybased context modelling that makes it easy to combine context models and contextual reasoning mechanisms. On the context modelling side, we outline our idea of a user-centric context model based on the six fundamental context parameters of who, when, where, what, how, and why (5W1H); on the contextual reasoning side, we introduce syntax and semantics for a simple logical language and sketch a tableau mechanism for reasoning. The model-theoretic semantics for this logical language is like the context model based on the parameters of 5W1H. With the common semantics, it is then easy to show the link between context modelling and contextual reasoning. 1
