Abstract

Electronic catalog contains ich semantics associated with products, and serves as a challenging practical domain for ontology application. Ontology is concerned with the nature and relations of being. It can play a crucial role in e-commerce as a formalization of e-Catalogs. Description Logics provide a theoretical core for most of the current ontology languages. In this paper, we present an ontological model of e-Catalogs in DL. We take an Extended Entity Relationship approach for conceptual modeling method, and present the fundamental set of modeling constructs and corresponding description language representation for each construct. Additional semantic knowledge can be represented directly in DL. Our modeling language stands within SHIQ(d) which is known reasonably practical with regard to its expressiveness and complexity. We illustrate sample scenarios to show how our approach may be utilized in modeling e-Catalogs, and also implement the scenarios through a DL inference tool to see the practical feasibility.

전자카타로그는 상품에 관한 풍부한 의미를 포함하며 온톨로지가 적용될 여지가 높은 영역이다. 온톨로지는 사물의 본질과 사물간의 관계를 나타내는데, 전자카탈로그를 형식적(formal)인 온톨로지로 표현하는 것은 전자상거래 영역에서 중요하다. DL(Description Logic)은 현재 사용되는 여러 온톨로지 언어의 이론적 기반을 제공한다. 본 논문은 DL 언어를 사용해 전자카타로그를 형식적으로 온톨로지 모델링 한다. 기본적인 모델링 구성요소 집합은 화장 개체 관계(Extended Entity Relationship)로 개념적으로 나타내고, DL 언어로 대응해서 변환한다. EER로 나타낼 수 없는 부가적인 의미적 지식은 직접 DL언어로 표현한다. 논문에서 제시하는 모델링 언어는 언어의 표현력과 복잡도를 고려할 때, 현실적으로 추론에 적합하다고 알려져 있는 SHIQ(d) 언어 범위에 기반하고 있다. 모델링한 온톨로지 e-카타로그의 활용 이해를 돕기 위해 시나리오를 제시하고, 실제 DL 추론 도구를 통해 그 시험적 검증을 한다.
