In this study it is intended to develop the ontology which can express the relation between objects with emphasis on the structural representation of semantics. Its interoperability with other kinds of previous ontology and metadata was also considered so that the developed ontology may be applicable to the real situation. The ABC Ontology can get extended into another field where the application of the concept of event is possible, for ABC Ontology provides the fundamental framework on the axis of event. In this study it is Music where ABC Ontology can be applied properly, which results in creating Music Ontology. Music Ontology provides the infrastructure of knowledge for reasoning of potential meaning as well as the simple semantic connection of terms. The extended model of ABC Ontology has been developed by applying Music Ontology, which is the domain ontology and conveys meaning, to ABC Ontology that represents the whole framework. The representation of conceptual relation in ABC Ontology turns into the association of the framework and meaning in the extended model of ABC Ontology, with reasoning rules which are typical in ontology. Also, interoperability of the extended model of ABC Ontology is examined in consideration of co-operating with metadata different from those in it. 핵심되는 말: ABC 온톨로지, 이벤트, 메타데이터 상호운용성, 음악 온톨로지, 온톨로지 통합, OWL

초록

본 연구는 W3C를 중심으로 시맨틱 웹을 위한 표준 온톨로지 언어로 제안된 OWL(Web Ontology Language)을 바탕으로 패싯형 시소러스인 AAT(Art and Architecture Thesaurus)의 개념 체계를 이용한 온톨로지 스키마를 구현하여 시맨틱 웹 환경의 온톨로지 기반 시스템을 구축하였다. 특히, 개념의 범위를 AAT의 Furniture 패싯 이하의 용어에 한정하였고 이 중 개념관계가 다양하고 많은 어휘를 가진 하위 패싯인 Chair 개념을 중심으로 시스템 구현 및 테스트를 하였다. 이 시스템은 온톨로지로 정의된 개념을 검색하며, 동의어에 대해 항상 우선어(Preferred term)를 제시하여 어휘를 제어한다. 또한 질의어를 중심으로 한 용어간의 관계를 이용자에게 제시하고 관련어 및 개념의 분류기준 속성을 제시한다. 그 밖에 개념에 인스턴스 값을 입력하고 이를 RDF 문서로 재생산하는 시스템을 구축하여 온톨로지 시스템 응용의 일례를 제시하였다. 이 과정에서 여러 온톨로지를 도입하였고, 인스턴스 값을 담기위한 컨테이너 기반으로 메타데이터 요소를 사용하였다.

Abstract

The purpose of the study was to construct a system based on the semantic web environment's ontology by utilizing the ontology schema derived from the facet-type Art and Architecture Thesaurus(AAT). The aforementioned ontology schema is based on the Web Ontology Language(OWL), which is being widely considered the standard ontology language for the W3C-centered semantic web environment. Also, the concepts were limited to terms within AAT's Furniture Facet, and the system was tested using the Chair concept, which is a lower-level facet that has a diverse conceptual relationship and broad vocabulary base. The ontology system is capable of searching for concepts, while controlling the search results by always providing a 'Preferred term' for synonymous terms. In addition, the system provides the user with first, a relationship between the terms centered around the inquiry, and second, related terms along with their classification properties. Also, the system is presented as an application example of the ontology system that constructs a information system that intakes an Instance value and reproduces it into a RDF file. During this process, utilization of multiple ontologies was introduced, and the stored Instance value's meta-data elements were used.
