This study is to analyze the characteristics of 2019 revised RDA and suggest the consideration in aspects of cataloging using the literature reviews. The following 3 things are suggested with analyzing the revised RDA. First, high quality data such as supplementing cataloging data and constructing vocabulary encoding schemes should be needed to transform bibliographic data to linked data for the semantic web. Second, MARC should be expanded to accept the new conept of LRM and linked data being reflected in revised RDA because MARC is the unique encoding format untile linked data will be transformed from MARC data. Third, the policy statement and the application profile are needed for describing resource consistently because each entity and element has own condition and option, and there are different elements for applying rules in revised RDA. Based on this study, the RDA related researches should be in progress such as exapanding BIBFRAME as well as MARC to accept the new concepts in revised RDA, and, also, reflecting and accepting RDA being able to use revised RDA rules and registries in libraries and nations that have been faced to revise their own cataloging rules.

Interdisciplinary approach has been recognized as one of key strategies to address various and complex research problems in modern science. The purpose of this study is to investigate the interdisciplinary characteristics and structure of the field of big data. Among the 1,083 journals related to the field of big data, multiple Subject Categories (SC) from the Web of Science were assigned to 420 journals (38.8%) and 239 journals (22.1%) were assigned with the SCs from different fields. These results show that the field of big data indicates the characteristics of interdisciplinarity. In addition, through bibliographic coupling network analysis of top 56 journals, 10 clusters in the network were recognized. Among the 10 clusters, 7 clusters were from computer science field focusing on technical aspects such as storing, processing and analyzing the data. The results of cluster analysis also identified multiple research works of analyzing and utilizing big data in various fields such as science & technology, engineering, communication, law, geography, bio-engineering and etc. Finally, with measuring three types of centrality (betweenness centrality, nearest centrality, triangle betweenness centrality) of journals, computer science journals appeared to have strong impact and subjective relations to other fields in the network.

This study discussed the problems of internet search engines or metadata and the necessity to catalog the digital information resources including information resources on the networks in libraries. The internet search engines or metadata make digital information resources indexed or organized immediately. But traditional library bibliographic tools like catalog should be described accurately and fully, and standardized in addition to the rapidity. Therefore from the library standpoint, digital information resources should be cataloged fully too. Cataloging cost of the increasing digital information resources can be reduced by cooperating and sharing the works among the libraries.

This study aims to clearly understand 'Functional Requisite of Authority Data(FRAD)' being studied by IFLA focused on aspect of change from FRAR. In addition, it has established relationship between FRAD and concerned rules by analyzing effect of FRAD on RDA and MARC21 and reviewed cataloguing rules, format and situations of major authority DB implementations concerned about domestic authority controls in reflection of IFLA's activities for authority control. Based on the analysis, it has looked into considerations for domestic authority controls standards such as access control methods, expansion of application scope, introduction of new approaches such as entity-relationship model, reinforcement of roles for national bibliographic agency. These study results would be utilized as basic data for authority control.

In this study, we aimed to identify the types of acknowledgments in Korean LIS journal articles and to find out whether there are differences in the bibliometric characteristics of journal articles based on the types of acknowledgments. For the analysis, the acknowledgments, references, and citation counts of 2,143 articles published in four representative journals in the field of library and information science in Korea for nine years from 2013 to 2021 were obtained as data. We analyzed the contents of 1,433 acknowledgments in 1,311 articles (61.2% of all articles) to divide them into types and then examined the bibliometric characteristics of each type of article. The acknowledgment types were broadly divided into the 'ethics' type (avoiding duplicate publication) and 'thanks' type, which were further subdivided into 9 and 10 types, respectively. We examined the number of references, recency of references, and citations as bibliometric characteristics, and found that all of these characteristics differed between the types of acknowledgements.

As the bibliographic environment has been evolved towards linked data and semantic web, revision of KCR5 based on RDA is also in progress in Korea. Even authorized access points play an important role in identification and linkage between resources in the evolving bibliographic environment. However, the original RDA applied by KCR5 does not provide authorized access points for all entities. Based on the analysis of the authorized access point of manifestation in RDA 2020, this research identified properties and proposed a linking structure of the authorized access point that can be applied to the revision of KCR5. An authorized access point for manifestation is an access point that considers both intellectual and physical aspects, and can be the foundation for linking and identifying actual resources. The proposed structure is expected to be a linking structure for authority record optimized to the current bibliographic environment, which can be helpful in the practical application of the authorized access point for manifestation.

Most information providers are offering integrated retrieval service based on the bibliographic metadata and schema corresponding to each type of document which are developed in a distributed and independent way. However, it is difficult to maintain the relational consistency of those single heterogeneous databases even though they obey the metadata standard like MARC or MODS. It is the main reason that those standards are restricted to present the general property of document regardless of its type and not to applied to define the relationship of document types. Therefore, It is necessary to define a comprehensive meta model to associate the related databases in a systematic way so that the semantically common part of them can be easily shared and reused without any additional effort like conversion or mapping. In this paper, we first outline the document types for designing meta model by the empirical analysis of various data schema of main information providers. We propose then data element definition, metadata model and modularized XML DTD which support the efficient and consistent management of multiple ducument types.

The purposes of this study are to explore FRBR utilities such as work clustering and expression clustering and problems of application of the FRBR by developing work and expression clustering algorithm and implementing it into cataloging system, and to suggest new cataloging rules for FRBR and guideline of MARC description to improve FRBR work clustering. FRBR was suggested by necessitation of collocation function of bibliographic records according to increase of searching materials and multi-version materials, but FRBRization has some problems such as imperfect conversion of bibliographic records to FRBR records and inappropriateness of current cataloging rules for FRBR. Bibliographic records must be processed by FRBR algorithm to construct FRBRized system, but bibliographic records and current cataloging rules couldn't perfectly support FRBRization. Therefore cataloging rules and guidelines of MARC description for FRBR are needed. For constructing FRBRized cataloging system in Korea, it is needed to find problems and solution through FRBR practical application such as developing FRBR algorithm and applying it to cataloging records.
