This study identifies the characteristics of recent citation-based indicators for assessing a single paper in the context of their co-relationships. Five predefined indicators were examined with three variants of h-index which are convened in this study; the formers are PageRank, SCEAS Rank, CCI, f-value, and single paper h-index and the latters are $h_S$-index, h1-index, and $h_S$1-index. The correlation analysis and cluster analysis were performed to group the indicators by common characteristics, after which the indicators were calculated with the dataset from KSCI DB. The results show statistical evidence that distinguishes h-index type indicators from others. The characteristics of the indicators were verified with citation frequency factors using correlation analysis. Finally, the implications for applications and further studies are discussed.

최근 Web of Science에 도입된 Eigenfactor지수와 논문 영향력 지수(Article Influence Score), 그리고 Scopus에 도입된 SJR 지수는 구글의 PageRank 알고리즘과 같은 네트워크 분석 방식의 인용지수이다. 국내 인용 색인 데이터베이스는 인용 링크가 외부로 향하는 비율과 자기 인용 비율이 높으므로 기존의 네트워크 인용 지수 산출 방식을 그대로 적용하기에는 어려움이 많다. 이 연구에서는 국내 인용색인DB에 대해서 대표적인 네트워크 인용 지수인 저널 페이지랭크를 시험적으로 측정해보고 국내 학술지의 상황을 고려한 개선방안을 모색하였다.

It needs to be considered that citing is net a static process but a dynamic process which is to produce to reproduce and to distribute knowledge by the interaction between societies surrounding the citer. This study begins by briefly acknowledging that citation is a universal practice in terms of establishing citer's own basis of research on the basis of the relation to previous studies and persuadeing potential citer to cite his/her research product. This study, however, is a preliminary attempt to examine the premise that although citing is a unversal practice. but citer motivations can be influenced by various citation environmental contexts surrounding the citer. This study presented general citation motivations derived from previous studies: (1) substantial motivations - conceptional and methodological citations 2) persuasive motivations - positive, applied, and negative citations, (3) perfunctory motivations - perfunctory and bibliographic citations, and (4) social relation motivations - personal connections and knowledge familiarity citations. In addition, this study identified citation environment factors affecting these citation motivations: (1) citer and documentation factor, (2) social and cultural environment, (3) information environment, and (4) international knowledge system environment. Each citation environment factor presented should be interpreted not as a separate factor, but rather as a close interrelation among these environment factors, Finally, the model of the citation environment factors developed in this study was discussed in the aspects of the relationship between citation motivations and their citation environment factors. This study suggested that further research should be conducted in order to examine these relationships more empirically and citation should be considered as a social product reflecting the interaction between citer and various citation environments.

A large and reliable citation database is necessary to identify and analyze citation behavior of Korean researchers in science and technology. Korea Institute of Science and Technology Information (KISTI) built the Korea Science Citation Database (KSCD), and have provided Korea Science Citation Index (KSCI) and Korea Journal Citation Reports (KJCR) services. In this article, citing behavior of Korean scientists on Korean journals was examined by using the KSCD that covers 459 Korean core journals. This research dealt with (1) statistical numeric information of journals in KSCD, (2) analysis of document types cited, (3) ratio of domestic to international documents cited and ratio of citing different disciplines, (4) analysis on immediacy index, peak time, and half-life of cited documents, and (5) analysis on impact of journals based on KJCR citation indicators. From this research, we could find the immediacy citation rate (average 2.36%), peak-time (average 1.7 years) and half-life (average 5.2 years) of cited journals in Korea. We also found that the average journal self-citation rate is more than 50% in every field. In sum, citing behavior of Korean scientists on Korean journals was comprehensively identified from this research.

The citation information of academic resources contains the knowledge flow from previous research, so it is possible to connect fragmented research in relational aspects. The citation information can grasp the overall flow of research, so it can promote convergence research such as developing existing research or deriving related fields. Therefore, in this study, the citation information of academic literature, which was previously provided at the level of simple disclosure, was reconstructed based on the citation relationship. Through this, backward and forward citation analysis were conducted based on time series, and the research flow was analyzed by setting the citation stage. Finally, we developed an academic information service that visualizes the main research contents of backward and forward citation based on time series. This accesses academic resources through the meaning contained in the citation information.

한국암석학회에서 발간하는 암석학회지에 지난 10년간 수록된 논문들이 여러 학술지에 얼마나 인용되고 있는지에 대한 통계조사를 실시하였다 대상학술지는 암석학회지 자체를 비롯하여 SCI 등재 국제학술지, 그리고 관련된 분야에서 국내의 대표적 학술지라고 생각할 수 있는 지질학회지, Geosciences Journal, 자원환경지질, 지구과학회지를 대상으로 하였다. 결과를 보면 지난 10년간 암석학회지에 수록된 논문의 수는 논평과 단보를 포함하여 총152편이며 가장 많은 논문을 게재한 저자는 김형식으로 21편의 논문을 게재하였다 암석학회지 논문의 피인용 회수는 총370회로 암석학회지에 가장 많은 158회 인용되었으며. SCI 학술지에는 46회 인용된 것으로 조사되었고, 다른 국내 학국지 중에서는 지질학회지에 72회로 가장 많이 인용되었다 가장 많은 피인용 빈도를 보인 논문은 Liu(1993)로 총 27회이고, 가장 많은 피인용 회수를 보인 저자는 권성택으로 81회이다. 다른 국내학술지들의 피인용 통계자료가 없어 직접적인 비교를 하기는 어렵지만 관련 분야의 학술지 중에서는 피인용 정도가 정상급 수준이라고 판단된다. 그러나 아직 여러 기준으로 볼 때 수준급인 국제학술지와는 차이가 있으며 더욱 개선되어야 할 것으로 생각한다.

In this study, we testify that network structural attributes of a citation network can explain other aspects of journal citation behaviors and the importances of journals. And we also testify various citation impact indicators of journals including JIF and h-index to verify the difference among them especially focused on their ability to explain an institution's local features of citation behaviors. An institutional citation network is derived using the articles published in 2006-2007 by biotechnology faculties of Y University. And various journal citation impact indicators including JIF, SJR, h-index, EigenFactor, JII are gathered from different service sites such as Web of Science, SCImago, EigenFactor.com, Journal-Ranking.com. As a results, we can explain the institution's 5 research domains with inter-citation network. And we find that the co-citation network structural features can show explanations on the patterns of institutional journal citation behavior different from the simple cited frequency of the institution or patterns based on general citation indicators. Also We find that journal ranks with various citation indicators have differences and it implies that total-based indices, average-based indices, and hybrid index(h-index) explain different aspects of journal citation pattern. We also reveal that the coverage of citation DB doesn't be a matter in the journal ranking. Analyzing the citation networks derived from an institution's research outputs can be a useful and effective method in developing several library services.

Ciatation analysis is a information analysis method based on the phenomenon of citing previous documents in the source document. There are many well-known studies exploring citation analysis and it applications. This paper does not attempt to review this extensive area of applications, but to demonstrate the sociological aspect of citation analysis. Specifically, this paper have reviewed the citation analysis as a quantitative method for the studies of sociology of knowledge. For this, I have described various basic methods such as citation behavior, citation count, impact factor, citation relationship etc. And I have classified into four applied areas of sociology of knowledge; (1) flow of knowledge resources, (2) evaluation of knowledge resources, (3) evaluation of knowledge community, and (4) utilization in terms of knowledge policy. Finally, I have clarified the some limitations and shortcomings of citation analysis that have addressed by citation and citation analysis itself.
