Abstract

코호트 DB(DataBase)를 이용하여 질병 발생 예측 및 확산을 추적하는 많은 연구가 진행되고 있다. 코호트 DB는 대용량의 질병 및 건강정보가 단순한 개별적인 DB 테이블의 집합으로 구성되어있어 연관관계 검색을 위해서는 코호트 DB를 연구 목적에 맞게 재구성하는 작업이 필요하다. 본 논문에서는 대용량 코호트 DB를 온톨로지 기반으로 구축하기 위해 XML descriptor, editor를 이용하였다. 또한, 원활한 연관관계 검색결과 확인을 위해 온톨로지 기반의 코호트 DB 검색 시스템과 UI를 개발하였다. XML editor에서는 코호트 DB를 온톨로지로 구성하기 위해 7단계로 구성된 Ontology development 101 방법론과 OWL(Ontology Web Language) API를 이용하였다. 이와 같은 온톨로지 기반 코호트 DB 검색 시스템은 질병 및 건강정보의 연관성을 측정하고 의미적인 연관관계를 검색 시 효과적으로 활용 가능하다. Many researchers have used cohort DB (database) to predict the occurrence of disease or to keep track of disease spread. Cohort DB is Big Data which has simply stored disease and health information as separated DB table sets. To measure the relations between health information, It is necessary to reconstruct cohort DB which follows research purpose. In this paper, XML descriptor, editor has been used to construct ontology-based Big Data cohort DB. Also, we have developed ontology based cohort DB search system to check results of relations between health information. XML editor has used 7 layered Ontology development 101 and OWL API to change cohort DB into ontology-based. Ontology-based cohort DB system can measure the relation of disease and health information and can be used effectively when semantic relations are found. We have developed ontology-based cohort DB search system which can measure the relations between disease and health information. And it is very effective when searched results are semantic relations.
