The ontology-based EPC automatic conversion method includes the steps of arranging existing Radio Frequency Identification (RFID) EPC ontology information and newly added EPC ontology information, converting tag data collected from an RFID reader into binary data so as to perform header information extraction and Uniform Resource Name (URN) conversion, extracting the header information of an EPC from the binary data output as a result of the conversion, initializing the ontology properties so as to utilize the EPC ontology, extracting a corresponding code system of the ontology by performing comparison with the header information of the tag data converted into the binary data, extracting the ontology properties from the corresponding code system of the ontology, and performing automatic conversion into URN-type data on the basis of information about the extracted ontology properties.	03-18-2010
