6. A context aware method comprising: extracting, from a semantic model, a terminological-box (T-box) comprising information that defines a relationship between classes; generating a reasoning rule based on the T-box; generating a first assertion box (A-box) based on sensing information, wherein the sensing information relates to information sensed to recognize a user state; and inferring a user context based on the reasoning rule and the first A-box.
