Abstract

This paper proposes 3D visualization method of compound knowledge which will be able to identify and search easily compound knowledge objects based the multidimensional relationship. For this, we structurized a compound knowledge with link and node which become the semantic network. and we suggested 3D visualization method using SOM. Also, to arrange compound knowledge from 3D space and to provide the chance of realistic and intuitional information retrieval to the user, we proposed compound knowledge 3D clustering methods using object similarity. Compound knowledge 3D visualization and clustering using SOM will be the optimum method to appear context of compound knowledge and connectivity in space-time.

본 연구는 복합지식 객체를 기반으로 다차원적인 관계를 쉽게 식별하고 검색할 수 있도록 복합지식의 3D 가시화방법을 제안한다. 이를 위해 복합지식을 네트워크 형태의 의미화된 링크와 노드로 구조화하고 3차원 형태로 보여줄 수 있도록 SOM을 이용한 가시화방법을 제안하였다. 또한, 3D 공간상에서 복합지식을 배치하고 사용자에게 제공함으로써 보다 실감적이고 직관적인 정보검색의 기회를 제공하기 위해서 객체 유사도를 이용한 복합지식의 3D 클러스터링 방법을 제안하였다. SOM을 이용한 복합지식의 3D 가시화와 클러스터링은 복합지식의 맥락과 연계성을 시공간에 가시화하는데 최적의 방법이 될 수 있다.
