ONTOLOGY MATCHING METHOD USING BROADER TERMS

摘要

PURPOSE: An ontology matching method using broader terms is provided to supply a result most proper to the expansion of ontology by deducing a category system relationship that is most proper to the category system expansion of given ontology. CONSTITUTION: The broader terms for given words are extracted by using a category structure of structured data(S10). An attributing graph is deduced from the broader terms(S20) and is analyzed by using a hits link analysis algorithm(S30). The matching score for each concept of ontology is generated by using the analysis result(S40). The concept of the ontology matched with a given word is selected based on the matching score(S50).
