  • In this study, Linked Data was used for extending bibliographic data, because Linked Data provides shareable identifiers, data structures, and link information. Linked Data is especially efficient in expanding bibliographic data integrated with bibliographic ontology. Therefore, Linked Data and bibliographic ontologies were analyzed and available Linked Data was suggested. By linking between meta-data schemes, bibliographic data, and authority data, issues for the effective Linked Data sharing were suggested: 1) selecting proper Linked Data for each bibliographic organization, 2) linking between different Linked Data, and 3) developing their own Linked Data for each bibliographic organization.

  • Linked Data is about using the web to link related data that wasn't linked previously. To publish linked data, people should be able to represent, share, and link pieces of data, information, and knowledge by using URIs and RDF. However, building linked data is not easy for the common users who do not know the knowledge or skill about using URIs and RDF. In this paper, we present a system that the common users can create linked data by connecting data originated from different RDFs. They build linked data by adding new links to connect between RDF data saved in their computers or searched from Swoogle. We can apply the proposed system to creating educational contents. For example, teachers can develop various learning contents by building linked data that connects different data suited to the learning level of their students.

  • With high interest in linked data, there are various attempts to accommodate the linked data model in cataloging process. This study intends to discuss how to adopt and make the best use of linked data based bibliographic framework in order to improve the quality of library catalogs and to enhance library services in Korean libraries. To the end, this study focuses on (1) discussion of the meaning of linked data from the library cataloging perspective, (2) tracking best practices for implementing and operating linked data among North American and Europe libraries and bibliographic networks (in detail, constructing various types of ontology, developing linked data model including BIBFRAME and OCLC linked model, and improving retrieval service and interface), and finally (3) exploring problems and the anticipated challenges to transition to the linked data model in Korea. The data for discussion were collected from literature review and case study.

  • The institutional repository and linked data share a purpose, co-creation and joint usage of information resources. Therefore, a new approach linking these two concepts can be utilized for co-production and utilization of resources. This study hoped to configure the Korean dCollection repository as linked data. For this purpose, first, we analyzed the current data structure of dColleciton. Second, we investigated the resource types which dCollection is targeting. Third, we focused and analyzed a case study of resource types targeted by dCollection constructed as linked data. Fourth, this study examined in detail how to build the linked dCollection data and how to connect this linked data to the linked cloud. Finally, we discussed the problems that might oc cur in the process of building the linked data.

Expanding the Scope of Identifying and Linking of Personal Information in Linked Data: Focusing on the Linked Data of National Library of Korea (링크드 데이터에서 인물 정보의 식별 및 연계 범위 확장에 관한 연구: 국립중앙도서관 링크드 데이터를 중심으로)

  • This study analyzed the methods for representing and linking personal information in the linked data of National Library of Korea and provided suggestions for expanding the scope of identifying and linking of the personal information. As a result, the personal information as a subject has been dealt with a concept, where the personal information as a contributor has been linked with a vocabulary of personal name. In addition, there have not been assured of including additional information except existing authority data in the process of building the linked data. Therefore, this study suggested that linking personal information as a subject and personal information as a contributor was essential for the quality of linked data. In addition, we proposed to provide additional information related to the person in linked data for expanding the scope of access points in information discovery.

  • 본고에서는 교육내용 성취기준 링크드데이터 프로파일 설계 및 활용에 대해 소개한다. 성취기준은 학생들이 학습의 결과로 반드시 알아야 할 지식, 능력 및 태도를 구체적으로 명시한 것으로서 국가 교육과정의 중요한 요소로 인식되고 있다. 따라서 교수학습지원시스템은 성취기준 링크드데이터 프로파일을 기반으로 교육과정, 수럽계획, 학습자원, 평가 등을 연계할 수 있도록 구현되어야 한다.

  • The purpose of this study is to find the cause and solution of the situation where library LOD does not spread after the introduction of library LOD. Research methods include literature research, case studies, and expert interviews. The improvement plan presented in this study is that first, the library needs to avoid the redundancy of the LOD construction target and build the only and specialized data. Second, libraries need to develop LOD services that reflect user needs and implement convenient LOD interfaces. Third, libraries need to establish identification system of data and build a authority file. Fourth, libraries need to recognize the necessity of data opening and linking to librarians and users, and provide opportunities for education and publicity. Fifth, it is necessary to use LOD for integrated search and to establish an integrated platform for search of library LOD. Sixth, libraries need to strengthen cooperation for LOD issuance and utilization, and form a working-level consultative body. Seventh, the government should pursue strong policies with a continuous commitment to LOD promotion and need to continue to provide budget support.

  • News organizations are looking for a way that can be reused accumulated intellectual property in order to find a new insights. BBC is a worldwide media that continually enhances the value of the news articles by using Linked Data model. Thus, utilizing the Linked Data model, by reusing the stored articles, can significantly improve the value of news articles. In this paper, we conducted a study of Linked Data construction for the healthcare news from a newspaper company. The object names associated with medical description or connected to other published information have been constructed into Linked Open Data service. The results of the study are to systematically organize the news data that were accumulated rashly, and to provide the opportunity to find new insights that could not be found before by connecting to other published information. It may be able to contribute to reused news data. Finally, using SPARQL query language can contribute to interactively searched news data.
