Abstract

The many researches on context-aware service based on the combination of semantic technology and IoT environment are being actively done. However, the previous study exploiting ontology has limitations not to accommodate the service requirement changes due to ontology prebuilt by specific service scenario. Although the concept of cross vertical ontology has emerged in order to overcome the limitation, it has other limitations that need additional components composing service environment for expressing context information and can't represent state information of environment elements. To cope with these limitations, we propose SISO (Semantic-based IoT Service Ontology) that can represent the states of environmental element without the need for additional context-information element. To verify SISO's characteristics, we select the service scenario and present applied results. The qualitative analysis comparing with the previous study is also presented by the applied results of service scenario.

IoT 기술과 시맨틱 기술의 결합을 통한 상황인지 기반의 서비스를 제공하는 많은 연구가 활발하게 진행 중이다. 하지만 시맨틱 기술인 온톨로지를 이용한 서비스를 제공하는 선행 연구는 특정 서비스 시나리오를 도메인으로 선정하여 온톨로지를 구축했기 때문에 서비스 요구사항 등의 변경을 수용하기에는 한계를 가지고 있다. 이를 극복하기 위해 크로스 버티컬 온톨로지 개념이 등장하였지만 상황정보를 표현하기 위해 서비스 환경을 구성하는 요소 이외의 추가적인 요소를 필요로 하며, 환경구성요소의 상태정보를 표현하지 못하는 한계가 있다. 이와 같은 한계를 극복하기 위해 본 논문은 상황정보를 표현하기 위한 요소를 추가하지 않으면서, 환경구성요소의 상태표현이 가능한 SISO(Semantic-based IoT Service Ontology)를 제안한다. 이와 같은 SISO의 특징을 검증하기 위해 서비스 시나리오를 선정하고, 시나리오에 따라 적용한 결과를 제시하였다. 또한 서비스 시나리오 적용 결과를 기반으로 선행연구와의 정성적 비교결과를 제시하였다.
