Objectives: We incorporated the Korean Electronic Data Interchange (EDI) vocabulary into Observational Medical OutcomesPartnership (OMOP) vocabulary using a semi-automated process. The goal of this study was to improve the KoreanEDI as a standard medical ontology in Korea. Methods: We incorporated the EDI vocabulary into OMOP vocabularythrough four main steps. First, we improved the current classification of EDI domains and separated medical services intoprocedures and measurements. Second, each EDI concept was assigned a unique identifier and validity dates. Third, we builta vertical hierarchy between EDI concepts, fully describing child concepts through relationships and attributes and linkingthem to parent terms. Finally, we added an English definition for each EDI concept. We translated the Korean definitions ofEDI concepts using Google.Cloud.Translation.V3, using a client library and manual translation. We evaluated the EDI using11 auditing criteria for controlled vocabularies. Results: We incorporated 313,431 concepts from the EDI to the OMOP StandardizedVocabularies. For 10 of the 11 auditing criteria, EDI showed a better quality index within the OMOP vocabularythan in the original EDI vocabulary. Conclusions: The incorporation of the EDI vocabulary into the OMOP StandardizedVocabularies allows better standardization to facilitate network research. Our research provides a promising model for mappingKorean medical information into a global standard terminology system, although a comprehensive mapping of officialvocabulary remains to be done in the future.
