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.

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.

This study intended to make new suggestions by clarifying usefulness of analysis methodology for the intellectual structure of disciplines, which combines author co-citation analysis and author bibliographic coupling analysis. It also aimed to identify the recent research trend and key researchers recently doing research activities actively as well as the intellectual structure in the field of social welfare. It was found to be more efficient to conduct both author co-citation analysis and author bibliographic coupling analysis in order to identify traditional sub-areas of disciplinary subject or the research trend of actual researchers in examining the intellectual structure of a specific discipline.

Niklas Luhmann is a sociologist who has had a strong influence on other disciplines. Therefore, it is necessary to examine what Luhmann's theory has influenced on his subsequent researchers. This study analyzed the knowledge network of studies on Niklas Luhmann's theory by follow-up researchers. Bibliographic coupling and co-citation were used as the analysis method of knowledge network. The main results are as follows. First, the language clusters were divided into Latin American / Spanish-speaking regions, Western Europe / Anglo-American regions, Eastern / Northern Europe and other language regions through bibliographic coupling analysis. Second, from the node analysis of bibliographic coupling, It was divided into 2 main cases: where Luhmann's major works were cited; where Luhmann's minor works were cited. Third, it was found that there are the core work groups that are repeatedly cited among Luhmann's works. Fourth, 12 core works were derived from the node analysis of the co-citation network, and appeared in four groups according to themes.

최근 특정 주제의 지적 구조를 파악하기 위한 저자 동시인용분석, 동시단어분석, 서지결합법 등 계량정보분석에 대한 연구가 활발히 진행되고 있다. 그러나 국내의 경우 계량정보분석 기법을 활용한 정보 유통 프레임웍을 갖추고 있는 연구기관이나 대학이 아직 없는 실정이다. 그 이유는 특허나 과학문헌에 대한 인용정보를 보유한 곳이 없고, 거대 인용정보 행렬을 계산하기 위한 컴퓨팅 자원을 확보하지 못하고 있기 때문이다. 본 연구는 미국 특허 데이터베이스를 대상으로 인용 피인용 행렬을 생성한 후, 클러스터 컴퓨터를 사용하여 동시인용과 서지결합빈도를 계산하고 그 결과를 이용자에게 제공하는 정보 유통 서비스 모델을 제시하고자 한다.

과학기술은 기술영역간의 관계를 통해 고유한 연구영역을 그리며 발달하며, 이는 학제의 다양성을 바탕으로 기존 기술들이 독특한 결합과정의 형성을 의미한다. 기술의 결합과정은 지식의 결합과정 관점으로 이해할 수 있다. 본 연구에서는 기존의 에너지산업과 다른 특성을 갖는 신 재생에너지의 기술발전경로를 '지식흐름'의 관점에서 탐색하여 신 재생에너지 연구의 학제 구조 및 다양성을 살펴보고자 한다. 계량서지학적 분석은 데이터 수집의 간편성 및 초기 연구결과물 분석에 적용할 수 있다는 장점에 의해 여러 분야에서 폭넓게 응용되어 왔다. 특히, A.L Porter(1984)에 의해 'citation'을 이용한 학제간관계 측정에 적용하여 계량서지학적 방법을 바탕으로 지식흐름을 관찰하는데 선구적인 방법을 제시하였다. 또한 Tijsen(1992)은 동시분류분석방법을 적용하여 네덜란드 에너지 연구분야의 학제구조를 분석하였고, Kajikawa(2007)은 에너지분야의 신기술인 태양전지와 연료전지에 한정하여 인용네트워크 분석을 수행하여 연구발전의 경향을 알아보았다. 이에 본 연구에서는 계량 서지학적 방법의 하나인 co-classification 방법론을 적용하여 태양광 분야 중 태양전지에 초점을 맞추어 학제 간 다양성 분석 연구를 수행 하였다. 태양광은 신 재생에너지 중 전후방연관 파급효과가 가장 큰 분야이며, 반도체 기반기술을 바탕으로 그 기술을 전개할 수 있기에 국내 산업과의 연관도가 높은 산업이다. 태양전지의 연구 동향 파악 및 고유의 연구영역을 도출을 분석하기 위한 기본 자료는 ISI의 'Web of Science'를 기반하여 수집하였다. 또한 태양광 연구의 연구구조 파악을 위하여 계량서지학분석의 하나인 'co-classification' 방법론을 추가적으로 적용하여 학제간의 분석을 수행하였다. 분석결과 1979-2009년까지의 태양전지 연구 논문 2,602개를 바탕으로 동시에 2개 이상의 SC를 포함한 논문은 총 논문의 51.8%이며, 출현한 SC는 65개로 분석되었다. 이 중 2개 이상의 SC가 동시에 출연한 횟수는 증가하는 경향을 가짐을 알 수 있었다. 이는 과학기술의 발전이 기술의 결합과정 또는 지식의 결합과정 관점으로 이해할 수 있음을 확인할 수 있었다.

This study uses the bibliometric analysis and author bibliographic coupling analysis (ABCA) to analyse the study of IT outsourcing in Korea and China by 2017 and determine the subject areas of the researcher and the intellectual structure which lays the foundation for future researchers in IT outsourcing area. For this study, through the National Digital Science Library (NDSL) of Korea and China Academic Journal network publishing Database (CAJD) of China, it collected the connected documents and found out authors whose work had been published more than twice. ABCA is utilized to visualize the author map which could find out the researchers and areas in meaningful way. The result show that the study of IT outsourcing in Korea came out earlier and developed further than that of China. The study in Korea has already come to the mature period. By contrast, China remains at somewhere between developing period and bottleneck period. The distribution of papers are still in the dispersed state. The author map shows a hot subject area in Korean researchers IT outsourcing strategy is and in chinese scholars IT outsourcing management.

Metaliteracy is a new framework that reframes information literacy. Metaliteracy is distinguished from information literacy through the intruduction of postmodernism, social constructivism and metacognition. However it has been not examined whether metaliteracy studies reflect the conceptual differences. Therefore, The purpose of the study is to observe research trends of metaliteracy on the difference from information literacy. In the study, literature reviews were conducted, and frequency analysis and knowledge network analysis(co-occurrence and bibliographic coupling) were conducted for 80 metaliteracy studies. The results of the study are as follows. As a result of co-occurrence analysis, metacognition(frequency 1st) and skills(degree centrality 1st, closeness centrality 1st, betweenness centrality 1st) appeared. Since metaliteracy criticizes skill-based information literacy, the result suggests that the concepts of information literacy and metaliteracy are mixed. On the other hand, as a result of bibliographic coupling analysis, studies with high bibliographic coupling explain the difference between information literacy and metaliteracy through metacognition.
