The purpose of this study is to investigate and analyze the obsolescence of documents according to their dates, types and locations of publication. The main results are as follows : The half-life of monographs is 12.09 years while those of articles and research papers are 9.68 and 8.93 years, respectively. Moreover, documents are most often cited by researchers within two years since their publication. Lastly, but not the least, the estimated weeding points for monographs, articles, and research papers, assuming that their weeding points have been realized when their accumulated citation rates reach 90%, are 40.15, 32.15, and 29.65 years, respectively.

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.

본 연구의 목적은 이학분야 국내학술지 중 DOI를 기반으로 하여 인용정보를 제공하고 있는 학술지를 대상으로 피인용정보를 분석하고 WoS, Scopus와 비교를 통해 유사점과 차이점을 찾는 것이다. DOI를 등록하고 있고 WoS, Scopus에 공통으로 등재되어있는 5종의 이학분야 학술지의 CrossRef 피인용정보를 분석한 결과 논문수가 많은 2개 학술지의 인용률이 높았으며 모두 낮은 자기인용률을 보이고 있다. 전체적으로 CrossRef의 고유논문은 논문수와 인용수가 가장 큰 학술지 1종만이 11%이고 나머지 4종의 학술지는 5% 미만으로 대부분 WoS, Scopus 논문에 포함되었다. DB별 비교를 위해 3년간(2008~2010) 발행된 논문의 피인용도를 확인한 결과 모든 학술지에서 WoS의 인용률이 가장 높았고 CrossRef의 경우 레코드 수는 많지만, 전문색인DB가 아니고 참고문헌 등록이 모두 이뤄지지 않아 인용률이 가장 낮았다. 하지만 CrossRef 고유논문비율이 11%인 학술지의 경우 Scopus 보다 인용률이 높은 것으로 나타났다.

This study analyzes types of primary sources cited by South Korean civil engineers. The results are as follows: 1) primary sources by preference are academic journal (55.7%), book (15.6%), seminar contents (10.2%). 2) documents published within last 10 years (26.1%) are cited most often. 3) domestic journal is the primary academic journal cited, and the finding is similar in preference of top-ranked primary reference (domestic and foreign combined). 4) In terms of time, domestic sources are preferred for up-to-date publications, and foreign sources for relatively non-recent publications. 5) The indices of influence and extemporaneity for both domestic and foreign sources do not show high numbers simultaneously.

저자동시인용 자료에 대한 분석 도구로 삼각매개중심성 (triangle betweenness centrality; TBC) 척도를 비롯하여 네 가지 새로운 척도를 제안하고 정보학 분야의 지적 구조 분석에 적용해보았다. 제안한 척도는 사회네트워크 분석 분야에서 사용되고 있는 여러 중심성 척도를 참고하여 동시인용 데이터에 적합하도륵 고안되었다. 검증을 위해서 이은숙, 정영미(2002)의 연구에서 수집한 1990년부터2000년까지 11년간 Journal of America Society for Information Science에 인용된 주요 저자50명의 동시인용 네트워크를 여러 중심성 척도를 사용해서 분석하였다. 전통적인 분석 도구인 다차원척도법이나 군집분석과 달리 중심성 척도를 통해서는 저작물에 반영된 개별 저자의 입지와 영향력에 대한 구체적인 분석이 가능하였다. 특히 삼각매개중심성 척도는 측정 범위의 조절이 자유로와서 지역적 중심성과 전역적 중심성을 모두 파악할 수 있는 것으로 나타났다.

In this study, it was investigated if there were some differences on the preference of researchers to grey literature among seven different subjects in the field of science and technology using citation analysis. The result shows that there were some differences among researchers, depending on the subject area. It also appears that the preference of grey literature of researchers is dissimilar in journals in English and journals in Korean, regardless of the subject area. Finally, partial correlation coefficient among nine different types of material was counted with the control of languages used and subject areas included. Among nine types of cited documents, the value of partial correlation coefficient between proceedings and miscellaneous is larger than that of any other coupled comparison This means that researchers who cite articles from proceedings tend to include information from miscellaneous at the same time.

본 연구는 의학 분야를 중심으로 A 대학교 의과대학 도서관의 Science Direct 전자학술지 이용통계와 Scopus 인용지수를 비교분석하였다. 이에 594종의 의학 분야 전자학술지를 추출하여, 그 이용통계와 Scopus 인용지수에 대해 빈도분석, 상관관계분석을 실시하였다. 그 결과 의학 분야 전자학술지의 이용이 소수의 학술지에 집중되어 있고, 그 이용통계와 인용지수 사이에 양의 상관관계가 성립함을 확인할 수 있었다.

This experimental study examines informetric analysis of World Wide Web based upon cocitation analysis of Web pages and features of Web resources in the field of communication studies. Cocitation analysis is basically performed to examine the intellectual structure of the communication studies in reflecting link count on the Web. The selected Web resources in the field are mapped in two dimensions based upon the similarities of cocitation frequency, correlation matrix, mutidimensional scale and cluster analysis. Cocitation analysis methods using organizational homepage, personal homepage, or Web index, to Web produced clustering of Web resources that had topical similarities. So far, although informetric analysis of Web resources is in the preliminary stage, it shows that Web can be a new tool for indicating the intellectual structure of a specific research field. In addition, this study analyzes characteristics of printing resources and Web resources, and differences of research methods in applying cocitation analysis.

This study comparatively investigated citation behavior of articles by researchers in the field of mechanical engineering in Korea and Japan. For the study 7, 515 citations from 202 articles covered in KSME, 243 articles covered in JSME, and 129 articles indexed in SCI are analysed. It identified the general citation behavior, the difference with citation behavior by publication place, low use of grey literature and Korean publications by Korean researchers, and the difference with citation behavior between Korean and Japan researchers.

A new technique for revealing the research fronts of a interdisciplinary discipline has been developed. Citation image makers profiling (CIMP) determines the relationships between research papers with the title words of the citing documents. We adapted this new technique to analyze the research fronts and hot topics in women's studies of Korea. By Korean Citation Index (KCI) data in 2015, we selected 148 papers cited more than 9 times as the core documents of women's studies. Analysis of intellectual structure using citation image makers profiling was performed with the 148 core documents and those citing papers. Document co-citation analysis was hindered by citation data sparsity, while CIMP method successfully revealed the structure of research fronts of Korean women's studies including 2 divisions and 6 subdivisions. The CIMP method suggested in this study has good potential to discover the characteristics of research fronts of interdisciplinary research domains.
