Abstract

Korea Digital Copyright Exchange of Korea Copyright Commission runs and manages copyrighted works and copyright license agreement, as well as assigns Integrated Copyright Number(ICN) to copyrighted works, also offers copyrighted works searching service. Keyword-based searching method based on ICN metadata provides results depending on the inclusion of metadata keyword. However, keyword-based searching method has limitations that cannot provide exact results that users need. Therefore, the essential method of offering exact result is needed. In this paper, we propose the semantic-based searching method about copyrighted works to increase the accuracy of searching results by extending ICN matadata to ontology, and implement the ontology of copyrighted works by defining relation and semantics about metadata elements. In order to compare semantic-based searching based on the ontology of copyrighted works with keyword-based searching method, the search results of each method according to 5 scenarios are presented and the accuracy of each method is compared.

한국저작권위원회 디지털저작권거래소는 저작물에 통합저작권관리번호(ICN)를 부여하고 이를 바탕으로 저작물 및 저작권이용허락계약에 대해 운영 관리하고 있으며, ICN이 부여된 저작물에 대해 통합검색 서비스를 제공하고 있다. 통합검색 서비스는 저작물의 ICN 메타데이터를 바탕으로 키워드 기반 검색 방법을 이용하여 메타데이터의 키워드 포함 여부에 따른 검색 결과를 제공한다. 하지만 키워드 기반 검색 방법은 이용자가 원하는 정확한 검색 결과를 제공하지 못하는 한계를 가지고 있다. 따라서 정확한 검색 결과를 제공할 수 있는 방법이 필요하다. 본 논문에서는 저작물에 대한 의미 기반 검색 방법의 적용 및 검색 결과의 높은 정확도를 제시하기 위해 ICN이 부여된 저작물의 ICN 메타데이터를 온톨로지로 확장하여 메타데이터 요소간의 관계 및 의미를 정의한 저작물 온톨로지를 구축하였다. 구축한 온톨로지에서 추론을 통한 의미 기반 검색의 가능함과 키워드 기반 검색 방법과의 정확도 비교를 위해 5가지 시나리오를 선정하였으며, 시나리오별 각 검색 방법의 결과 및 정확도의 비교 결과를 제시하였다.
