Probability-annotated Ontology Model for Context Awareness in Ubiquitous Computing Environment
Heon-Man Jung, Junghyun Lee · Journal of the Korea Society of Computer and Information · 2006
Current context-aware applications In ubiquitous computing environments make the assumption that the context they are dealing with is correct. However, in reality, both sensed and interpreted context informations are often uncertain or imperfect. In this paper, we propose a probability extension model to ontology-based model for rep resenting uncertain contexts and use Bayesian networks to resolve about uncertainty of context informations. The proposed model can support the development and operation of various context-aware services, which are required in the ubiquitous computing environment.
