摘要

PURPOSE: An import graph generation method and an apparatus thereof based on an ontology are provided to select necessary ontology by using an import graph and load selected ontology. CONSTITUTION: A query processing device generates an import graph by using nodes based on ontology(S300). The device analyzes an import relation between predetermined nodes(S302). The device generates a graph which sets directionality between nodes(S312).
