Ontology-based context-aware model by applying Bayesian network

By the rapid advancement of wireless network, study of context-awareness computing is actively proceeding for better setting up a ubiquitous computing environment. Context modelling is mostly popular technique among context-awareness service. In various method of context modelling, Ontology is most popular modelling. However, Ontology based system have disadvantage that the relation expression between objects can be complex. In this paper, we propose the ontology-based context aware model by using the Bayesian network based reasoning method and constructing service model to improve the problems. This model is applied for the scenario of smart campus situation. As a result, it was possible for reasoning uncertain situation and flexible reasoning to various situations.
