USER-CENTERED CONTEXT AWARENESS SYSTEM, CONTEXT TRANSLATION METHOD THEREFOR AND CASE-BASED INFERENCE METHOD THEREFOR

摘要

PURPOSE: A user-centric context-aware system, a contextual information converting method for the same, and a case-based reasoning method are provided to embody proper processing according to context data by the formation of a contextual information method based on learning algorithm through SRA and CMA. CONSTITUTION: A sensor generates sensor data about around resources. A CMA(Context Management Agent) changes the sensor data according to attribute and creates contextual information which is suitable for deduction. The context administration unit has an ontology-based context model for contextual information storage and controls the input and output of the contextual information. A SRA(Context Reasoning Agent) reasons the current context with reference to the context model, provides context-aware service corresponding to reasoning result, reflects feedback about the service, and embodies the learning about the rule of inference.
