Abstract

This paper designs a service-oriented wireless sensor network ontology model which can be used as a knowledge base in future ubiquitous computing. In contrast to legacy approaches, this paper defines the new service classes (ServiceProperty, LocationProperty, and PhysicalProperty), as well as their properties and constraints that enable the service-oriented service based on service items. The service item merging between the proposed model and the legacy ontology was processed using the "equivalentClass" object property of OWL. The Protege 3.3.1 and RACER 1.9.0 inference tools were used for the validation and consistency check of the proposed ontology model, respectively, and the results of service query was applied to the newly defined property in SPARQL language without reference to the properties of legacy ontology.

본 논문은 미래의 유비쿼터스 컴퓨팅에서 지식 데이터 베이스로 활용될 수 있는 서비스 지향 무선센서 네트워크 온톨로지 모델을 설계한다. 기존의 접근방식과 달리 본 논문은 사용자 중심의 서비스가 가능하도록 서비스 항목에 초점을 두고, 새로운 서비스 클래스(ServiceProperty, LocationProperty, PhysicalProperty)들과 이들에 대한 속성, 그리고 제한사항들을 정의하였다. 또한 기존 온톨로지(GML, SWE, SensorML, SUMO, OntoSensor)들과의 병합은 서비스항목들만을 고려하여 OWL의 오브젝트 프로퍼티인 "equivalentClass"을 사용하여 처리하였다. 제안된 모델의 설계와 타당성 검증은 각각 Protege 3.3.1과 추론 도구인 Racer 1.9.0을 이용하였으며, SPARQL 질의어를 사용하여 기존 온톨로지 내의 속성과 관계없이 새롭게 정의된 속성을 사용한 서비스 검색 결과를 제시하였다.
