Abstract
Ontology has many merits such as high expression power and extensibility etc. and there are some suggestion on development of ubiquitous environment using ontology. For collecting and analysing the context information in ubiquitous environment, we need a context-awareness system. For these reason, some context-awareness systems have been developed using ontology, but they have insufficient representation power of context information and are independent to domain. In this paper, we define the context type to improve the extensibility of context framework, and develop the context ontology adopting the defined contort type to represent or inference various context information. We define the ontology to be easily adopted the and domain. Also, we use SWRL to represent numerical formulas and Horn-Logic expression.
