Abstract: For efficiently sharing information and providing additional information service, one current trend in Korea and other countries is to build linked data and develop services by using the linked data. Although data interlinking is very important for the linked data, most linked data used in Korea adopt different classes and properties to result in the difficulty in data sharing and reusing. Enhanced connectivity and usability of linked data requires mapping between classes and properties in the schema level, and interlinking between instances in the instance level. This study suggests an upper ontology for ontology mapping between classes and properties in the schema level for various linked data built in Korea. Upper ontology modeling is implemented by analyzing linked data of each institute, specifying the principles of upper ontology design, modeling ontologies focusing on the types suggested in schema.org, and adding classes and properties. Ontology mapping between upper ontology and Korean linked data contributes to effective connection between Korean linked data and overseas linked data. Vitalized linked data-based connection contributes to improving information reusability and accessibility, which leads further development of various valuable information services.
