LAYER CONTEXT MODELING BASED CONTEXT-AWARENESS SYSTEM

摘要

PURPOSE: A context awareness system based on hierarchical context modeling is provided to use a mahalanobis distance for dividing a level of the hierarchical context modeling, thereby increasing the accuracy of context inference. CONSTITUTION: A context collection agent unit(110) collects lower level context information from a sensor device. A context awareness agent unit includes a context modeling unit(121) and a context inference unit(122). The context modeling unit models the context information by receiving the context information and using multi-hierarchical context modeling. The context inference unit infers the context information in a context model. An agent platform unit(130) communicates with the context collection agent unit and the context awareness agent unit by using a message transmission protocol.
