Abstract
본 논문에서는 토픽맵의 모델 특성을 고려한 토픽맵 매칭 및 통합 기법을 제안한다. 이전까지의 대부분의 스키마 매칭 연구들은 계산 시간의 효율성을 고려하지 않고 매칭 기법의 범용성 및 정확성을 높이기 위한 목적으로 개발되어 왔다. 그러나 현재 표준적인 온톨로지 언어로 RDF/OWL과 토픽맵이 사용되고 있으며 앞으로 많은 온톨로지들이 이들 언어로 구현될 것이다. 따라서 본 논문에서는 토픽맵 데이터 모델의 구조적 특성 및 제약조건을 고려하여 토픽 분할, 토픽명기반 매칭연산, 속성기반 매칭연산, 계층구조기반 매칭연산, 연관관계기반 매칭연산 및 통합 알고리즘을 개발함으로써 효과적이면서 효율적인 토픽맵 매칭 및 통합이 가능함을 보인다. In this paper, we propose a topic maps matching and merging approach based on the syntactic or semantic characteristics and constraints of the topic maps. Previous schema matching approaches have been developed to enhance effectiveness and generality of matching techniques. However they are inefficient because the approaches should transform input ontologies into graphs and take into account all the nodes and edges of the graphs, which ended up requiring a great amount of processing time. Now, standard languages for developing ontologies are RDF/OWL and Topic Maps. In this paper, we propose an enhanced version of matching and merging technique based on topic partitioning, several matching operations and merging conflict detection.
