웹 자원을 이용한 지리정보 온톨로지 확장

Populating Geo-ontology with Web resources

초록

시맨틱 웹과 지리정보가 접목된 시맨틱 지리정보 시스템에 대한 연구가 활발히 진행되어 왔다. 그러나 현재의 지리정보 시스템은 사용자의 비공간 정보 입력 및 검색이 특정 시스템에 종속적이라는 문제점을 지닌다. 이는 또한 풍부한 서비스 제공을 어렵게 한다. 따라서 이 논문에서는 비 구조화된 웹 자원으로부터 지리정보 온톨로지(Geo-ontology)를 확장할 수 있는 구현 모델을 제안한다. 제안 모델은 웹 온톨로지 인스턴스를 시스템에 독립적으로 확장할 수 있으며, 따라서 보다 풍부한 웹 서비스 개발이 가능하다. 마지막으로 대학교를 도메인으로 선정하여, 지리정보 온톨로지 구축 사례와 함께 인스턴스를 확장하는 프로토타입을 보인다.

Much research on semantic geographic information systems that incorporating the Semantic Web and geographic information has been actively studied. However, the existing geographic information systems have a system dependency problem that users can input and retrieve non-spatial information only in a specific system. It also causes difficulty in providing rich services. Therefore, this paper proposes an implementation model for population of Geo-ontology from non-structured Web resources. The proposed model can populate instances for Web ontology independently of systems, and thus it enables a richer Web service development. Finally, this paper shows the prototype that populates instances including a Geo-ontology building example for a University selected as an application domain.
