Author co-citation analysis with 20 authors from Korean Nutrition Literature were executed. The purpose of this study is to examine the meaning of bibliographic phenomena in Korean literature by co-citation and to approach the intellectural structure of nutrition field in view of multidimensional space. The analysis assumes that the more two author are cited together, the closer the relationship between them. The raw data are co-citation counts from the Korean Journal of Nutrition over the period 1986~1987. The resulting map shows (1) identifiable author groups of nutrition, (2) locations of these groups with respect to each other, (3) the degree of centrality and peripherality of author within groups, (4) the relationship between domestic authors and foreign authors.

The purpose of this study is to explore the potential contribution of citation metrics to improving the search performance of citation index databases. To this end, the study generated ten queries in the field of library and information science and conducted experiments based on the relevance assessment using 3,467 documents retrieved from the Web of Science and 60,734 documents published in 85 SSCI journals in the field of library and information science from 2000 to 2021. The experiments included re-ranking of the top 100 search results using citation metrics and search methods, query expansion experiments using vector space model retrieval systems, and the construction of a citation-based re-ranking system. The results are as follows: 1) Re-ranking using citation metrics differed from Web of Science's performance, acting as independent metrics. 2) Combining query term frequencies and citation counts positively affected performance. 3) Query expansion generally improved performance compared to the vector space model baseline. 4) User-based query expansion outperformed system-based. 5) Combining citation counts with suitability documents affected ranking within top suitability documents.

Purpose : We tried to check the accuracy of references in the Journal of the Korean Pediatric Society and Journals of the Korean Pediatric Subspecialty Societies. We also wanted to know the citation patterns of authors by analyzing the frequency of cited materials. Methods : Three journals were randomly selected from the 2000 issues of Journal of the Korean Pediatric Society and nine journals were selected mainly from the second half of 2000 issues of each Journal of the Korean Pediatric Subspecialty Societies for the study. Then the accuracy of references was checked with Medline. Journals before 1964, books, and journals which were not written in English were used only in the citation pattern analysis. Results : Author errors were the most common(21.3%) among the reference elements. The next was title errors, followed by page errors, journal errors, volume errors and year errors. Total average error rate was 34.7% and we were unable to find journals in 89 cases(2.2%). The journal of the Korean Society of Neonatology had the lowest error rate(17.4%) and the journal of the Korean Pediatric Cardiology Society had the highest error rate(53.2%). The reference journals which were published and quoted in the most recent three years were only 612 cases(15%). Foreign journals were selected as reference(78.4%) more than domestic journals; The Journal of the Korean Pediatric Society was the most frequently cited reference(43.3%) among domestic journals. Conclusion : Authors are ultimately responsible for the accuracy of references and they should check the reference list with responsibility. Hopefully, authors also will have to use more domestic journals and recent journals.

The purpose of this use study is to evaluate foreign science and technology serials with reference to the result of interlibrary loan activity and to present the model of cooperative acquisition. This study was based upon an analysis of actual use data by library users and Interlibrary loan from March 1, 2000 to February 28, 2001. 603 titles of foreign serials which were composed of 459 subscription titles of I University Library and 144 cooperative acquisition titles in the fields of science and technology were analyzed. The study reveals that only 439 serials(72.8%) were used even more once and 164 serials were not used at all during 1 year interval. A relationship was found between rankings of serials as measured by use and JCR citation ranking. Based upon various aspects of use analysis, this study suggested effective techniques for managing academic serials.

In the context of open science, data sharing and reuse are becoming important researchers' activities. Among the discussions about data sharing and reuse, data journals and data papers shows visible results. Data journals are published in many academic fields, and the number of papers is increasing. Unlike the data itself, data papers contain activities that cite and receive citations, thus creating their own intellectual structures. This study analyzed 14 data journals indexed by Web of Science, 6,086 data papers and 84,908 cited references to examine the intellectual structure of data journals and data papers in academic community. Along with the author's details, the co-citation analysis and bibliographic coupling analysis were visualized in network to identify the detailed subject areas. The results of the analysis show that the frequent authors, affiliated institutions, and countries are different from that of traditional journal papers. These results can be interpreted as mainly because the authors who can easily produce data publish data papers. In both co-citation and bibliographic analysis, analytical tools, databases, and genome composition were the main subtopic areas. The co-citation analysis resulted in nine clusters, with specific subject areas being water quality and climate. The bibliographic analysis consisted of a total of 27 components, and detailed subject areas such as ocean and atmosphere were identified in addition to water quality and climate. Notably, the subject areas of the social sciences have also emerged.

The purpose of this study was to identify bibliographic characteristics of the top level articles among KCI indexed academic articles. Unlike the existing analysis on citation and most-cited articles, this study analyzed their bibliographic characteristics. The 3,453 articles were collected from 17 social science fields in KCI. The characteristics of authors, institutions, publications, journals, and citations were analyzed. According to the result of the analysis, there was a difference in the ratio of single authors to co-authors and in the number of co-authors. The authors were mostly single authors or two co-authors. In general, the percentage of authors of one article was high. Second, the types of institutions were mostly universities, and there were differences in the number of institutions with authors in each field. And the frequency of the authors' affiliation appeared uneven. There were a number of excellent research institutes and authors depending on the field. Third, the average of years to take to become the top articles for publication was 11 years in 2018. Fourth, most of the published journals were KCI registered journals, and the influence of the journals was not a factor. Fifth, there were differences in the number of cited counts between fields. This study is meaningful to grasp the influencing factors on the bibliographic characteristics of the most-cited articles for the social science field.

This study aims to understand the research landscape of South Korea using the data of 2020 Google Scholar Metrics. To achieve the goal, we constructed and analyzed four types of networks including the university collaboration network, the keyword co-occurrence network, the journal citation network, and the discipline citation network. Through the analysis of the university collaboration network, we found major universities such as Seoul National University, Keimyung University, and Sungkyunkwan University that have led collaborative research. Job related keywords such as job change intention and job satisfaction have been frequently studied with other keywords. Through the analysis of the journal citation network, we found multiple journals such as The Journal of the Korea Contents Association, Korean Journal of Sociology, and Korean Journal of Culture and Social Issues that have been widely cited by the other journals and influenced them. Finally, Education, Business administration, and Social welfare were identified as the top influential disciplines that have influenced other disciplines through the knowledge diffusion. The study is the first of its kind to use the data of Google Scholar Metrics and conduct a stepwise network analysis (e.g., keyword, journal, and discipline) to broadly understand the research landscape of South Korea. Our results can be used by government agencies and universities to develop effective strategies of promoting university collaboration and interdisciplinary research.

Although domestic research funding organizations require patented technologies as an outcome of financial aids, they have much difficulty in evaluating qualitative value of the patented technology due to lack of systematic methods. Especially, because citation data is not essential to patent application in Korea, it is very difficult to evaluate a patent using the incomplete citation data. This study proposes a method for evaluating technology importance of a patent when there is no or insufficient citation data in patents. The technology importance of a patent can be evaluated objectively and quantitatively by the proposed method which consists of 5 steps such as selection of a target patent, collection of related patents, preparation of key word vector, clustering patents, and technological importance assessment. The method was applied to a patent on 'user identification method for payment using mobile terminal' in order to evaluate technology importance and demonstrate how the method works.
