A context-aware apparatus and a context-aware method are provided. The context-aware apparatus includes a context-model creating unit configured to create a context model based on input data; and a context reasoning unit configured to update a previously stored context model in a memory storage based on the created context model, and to infer a context using the updated context model and input data.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A context-aware apparatus comprising: a context-model creating unit configured to create a context model based on input data; and a context reasoning unit configured to update a previously stored context model in a memory storage based on the created context model, and to infer a context using the updated context model and the input data. 2. The context-aware apparatus of claim 1, wherein the previously stored context model comprises a key-value model, a markup scheme model, an object oriented model, a logic-based model, or an ontology-based model. 3. The context-aware apparatus of claim 1, wherein the context-model creating unit comprises a learning unit configured to learn the input data, and a conversion unit configured to convert learning outcomes of the learning unit into the context model by expressing the learning outcomes in a preset language. 4. The context-aware apparatus of claim 3, wherein the learning unit is configured to mechanically learn the input data for a preset learning period. 5. The context-aware apparatus of claim 3, wherein the preset language comprises a resource description framework (RDF), a web ontology language (OWL), N3, a rule markup language (RuleML), a semantic web rule language (SWRL), or a prolog. 6. The context-aware apparatus of claim 1, further comprising: a context-model input unit configured to receive the context model from outside. 7. The context-aware apparatus of claim 3, wherein the context-aware apparatus is a mobile device capable of wireless communication or network communication; and the context-aware apparatus is configured to obtain the input data from at least one of a proximity sensor, a microphone, a motion sensor, an illuminance sensor, a gyro sensor, an acceleration sensor, a temperature sensor, and a pressure sensor of the mobile device. 8. A context-aware method comprising: creating a context model based on input data; updating a previously stored context model in a memory storage based on the created context model; and inferring a context using the input data and the updated context model. 9. The context-aware method of claim 8, wherein the previously stored context model comprises a key-value model, a markup scheme model, an object oriented model, a logic-based model, or an ontology-based model. 10. The context-aware method of claim 8, wherein the creating of the context model comprises learning the input data, and converting learning outcomes of the learning of the input data into the context model by expressing the learning outcomes. 11. The context-aware method of claim 10, wherein the learning of the input data comprises mechanically learning the input data for a preset learning period. 12. The context-aware method of claim 10, wherein the preset language comprises RDF, OWL, N3, RuleML, SWRL, or a prolog. 13. A non-transitory computer-readable medium storing instructions that cause a computer to perform the method of claim 8. 14. A context-aware apparatus comprising: a context-model input unit configured to receive a context model from outside, the context model being based on learning of input data for a preset learning period; and a context reasoning unit configured to update a previously stored context model in a memory storage based on the received context model, and to infer a context using the updated context model and the input data. 15. The context-aware apparatus of claim 14, wherein the input data is obtained from a sensor comprising at least one of a proximity sensor, a microphone, a motion sensor, an illuminance sensor, a gyro sensor, an acceleration sensor, a temperature sensor, and a pressure sensor of a mobile device.
