  • Intellectual structure analysis, which quantitatively identifies the structure, characteristics, and sub-domains of fields, has rapidly increased in recent years. Analysis techniques traditionally used to conduct intellectual structure analysis research include bibliographic coupling analysis, co-citation analysis, co-occurrence analysis, and author bibliographic coupling analysis. This study proposes a novel intellectual structure analysis method, Keyword Bibliographic Coupling Analysis (KBCA). The Keyword Bibliographic Coupling Analysis (KBCA) is a variation of the author bibliographic coupling analysis, which targets keywords instead of authors. It calculates the number of references shared by two keywords to the degree of coupling between the two keywords. A set of 1,366 articles in the field of 'Open Data' searched in the Web of Science were collected using the proposed KBCA technique. A total of 63 keywords that appeared more than 7 times, extracted from 1,366 article sets, were selected as core keywords in the open data field. The intellectual structure presented by the KBCA technique with 63 key keywords identified the main areas of open government and open science and 10 sub-areas. On the other hand, the intellectual structure network of co-occurrence word analysis was found to be insufficient in the overall structure and detailed domain structure. This result can be considered because the KBCA sufficiently measures the relationship between keywords using the degree of bibliographic coupling.

  • This study was started on the premise that it was necessary to analyze the users and their needs of the national bibliography in order to develop a new national bibliographic service strategy. Based on this premise, the main purpose of this study is to analyze the users' situation and needs on the Korean national bibliography, and to establish a new service strategy that reflects the user's perspective. In addition, it has a secondary purpose to find the basis for justifying the value and persistence of the national bibliography from user. To this end, first, identified the main user groups of national bibliography through literature and case studies. The data were collected from a interview with 51 people from 4 groups (librarian, researcher, publishing distributor, end user) that are expected to use national bibliography. As a result of the interview, it was possible to confirm very low awareness and utilization of the national bibliography. In addition, the interview results revealed that there is a need for improvement in terms of the method of operating the national bibliography, the content to be provided, and service.

  • Author co-citation analysis(ACA) technique has been widely used for identifying research areas and trends in a discipline. But this technique has some limitations, mainly due to citation delay, on analyzing current trends and identifying active researchers. In this study, a new method, named as Bibliographic Author Coupling Analysis (BACA), is suggested for overcoming those limitations of author co-citation analysis. BACA is based on Kessler's bibliographic coupling approach and focuses not on documents but on authors. Simply stated, BACA technique assumes that those likewise citing authors have the same research interests. For the purpose of comparing with author co-citation analysis, two preceding studies with author co-citation analysis are reconsidered and re-examined using BACA. The comparing results can be regarded as promising the usefulness of BACA in analyzing current research trends and identifying active researchers.

  • The purpose of this article is to examine the research trends of 'bibliography' in Korea. By utilizing citation analysis methods, total 1,321 cited references of the 51 articles published by ${\ulcorner}Journal of the Institute of Bibliography{$\lrcorner}$ in 2000 and 2001 are analysed. This analysis is focused on an article's subjects and authors'occupations, the numbers and journal categories of its cited references. Also, this study observes the nationalities and languages of cited references and various items related to authors of cited references. The most of findings of this study are similar to the previous studies. However, it could find that there are minor differences from the existing literatures, in respect to subject areas, the number of cited references and the forms of cited references. In conclusion, this study recommends that bibliographers's collaborative works with related fields such as history and library and information science need to be strengthened, and that qualitative apaches as well as citation analysis methods might be beneficial for further expansion of academic scope of 'bibliography'.

  • The purpose of this paper is to development an algorithm for FRBR implementation(functional requirements for bibliographic records), analyzing KORMARC bibliographic records by work types. For this purpose, it was utilized analyzing home and foreign case studies including OCLC and LC's algorithm. Analyzing the experimental data from the Korean National Library's bibliographic records, it was extracted from identifying elements by FRBR's four bibliographic entities. To cluster a related works by work-set, the algorithm was designed to construct the authorized access points as a combination of an author name and a title from the record. I suggested that it should be wholly improved a quality of existing bibliographic records and level of data input to development a FRBR algorithm in Korean libraries.
