Mobile device and computer readable medium containig a program for perfoming reasoning engine based on hierarchical taxonomy

PURPOSE: A medium readable with a computer and a mobile terminal for implementing a hierarchical classification base inference engine is provided to efficiently manage the resource in an inference operation for implementing the hierarchical taxonomy based reasoning engine. CONSTITUTION: A classification network(120a) maps classification check nodes of the modified alpha network. The fact comprises the classification expression. The mobile terminal apparatus performs deduction with the activation of all classification check nodes. The property node is in accord with the classification expression. All classification check nodes are connected to the property node.
