In this study, Network Text Analysis was performed on 1,752 articles which had been published in recent 7 years and drew the subject concept distribution and their relations in Library and Information Science research areas. Furthermore, for analyzing more recent trends and changing aspects, this study performed secondary analysis based on 482 articles published in recent 2 years. Results show that "public library", and "academic library" concepts were most frequently studied in the field and "evaluation", "education", and "web" concepts showed the highest-degree centrality during the recent 7 years. In the result of recent two years analysis, "web", and "classification" concepts showed high frequency and "user", and "public library" showed an improvement in high degree centrality.

한 논문에 대하여 참고문헌의 인용빈도로 원 논문을 평가하는 outgrow index와, 인용논문의 인용빈도로 원 논문을 평가하는 single paper h-index를 비교해보았다. KCI 문헌정보학 분야 논문을 대상으로 시험 적용해본 결과 outgrow index의 값과 single paper h-index의 값이 비례하지 않음을 알 수 있었다. 한 논문을 outgrow index와 single paper h-index로 분석하여 다면적인 논문 평가 도구로 활용될 가능성을 검토해본다.

자동문서 범주화에 이용되는 학습분류기 중에서 SVM은 자질 차원을 축소하지 않고도 좋은 성능을 보이고 있다. 본 실험에서는 KTSET 텍스트 컬렉션을 대상으로 두 개의 SVM 분류기를 이용하여 자질축소 및 자질표현에 따른 성능비교 실험을 하였다. 자질축소를 위하여 $\chi$$^2$통계량을 자질선정기준으로 사용하였으며, 자질값으로는 단어빈도 및 문헌빈도의 두 요소로 구성되는 다양한 가중치를 사용하였다. 실험결과 SVM은 자질축소에 큰 영향을 받지 않고 가중치 유형에 따라 성능의 차이를 보였다.

This paper grasps about various features of the coauthorship network based on the co-author frequency in the Korean LIS Research Community. This issue includes many topics such as changable aspects of coauthorship network, properties of higher cooperative authors groups. This work is mostly analyzed through a bibliographic analysis of articles which is published from 2000 to 2009(10 years) in Korean Library & Information Science major four journals. The results show three major implications. 1) There is a various structural changes of coauthorship network on the change of the co-author frequency. 2) There are 21 research pairs in the higher cooperative authors groups with the co-author frequency more than five. 3) There seems that any subjective relations between the articles which is produced by 21 research pairs were not clearly presents.

As collaboration of research is increasing in social science, this study aims to investigate the changes in patterns of research collaboration in the field of library and information science, over the years from 2002 to 2020. The data used for this study were collected from four major journals in the field to analyze the frequency of co-authored research articles by journals and by institutions that all authors were associated with. Also, the institutions data were used to build a co-authorship network, which produced various indices including TBC (Triangle Betweenness Centrality) that showed which institutions were more central than others in the network. The result shows the number of co-authored articles were constantly increasing in all journals, and some institutions, mostly universities, showed the higher centrality scores than others and the range of collaboration were also expanded.

최근 국내외 ESG 연구가 활발해지고 있는 가운데, ESG 연구는 급격한 양적 성장을 하고 있음에도 학술지의 질적 수준을 평가할 수 있는 계량적인 논문은 부족한 상태이다. 본 연구는 한국학술지인용색인(KCI)에서 경영학 분야 내의 KCI 인용지수를 활용하여 상위 10개의 학회를 선정하고 이들 간의 ESG 논문 인용빈도와 네트워크 분석을 하였다. 상호 인용빈도를 활용하여 연결망을 작성하고 네트워크 분석 관점에서 ESG 주제에 관한 각 학술지 간 상호인용빈도를 통해 주어진 학술지의 영향력지수(Impact Factor)와 중심성 지수를 기초하여 연구하였다. 이러한 연구를 바탕으로 학술지들이 핵심 문헌을 식별하고 학문 내 지적 구조를 규명하여 경영학 분야의 ESG 연구 동향을 파악하고자 한다. 본 연구는 국내 발간된 경영학 학술지의 ESG에 대한 학술지의 영향력 인용지수를 비교해 보고 나아가 경영학 학술지의 자기 인용 비율을 확인하고 경영학뿐만 아니라 타 학문 분야에서 경영학 관련 학술지에 대한 인용이 이루어질 수 있도록 다학제적 교류와 추가 연구의 필요성을 제기하고자 한다.

본 논문에서는 벡터모델과 신경망 모델을 이용하여 데이터 퓨전의 관점에서 다중증거로서 가중치, 문헌분리가, 엔트로피, 공기유사도를 적절히 결합하여 질의를 확장하는 방법을 제안한다. 실험결과 코사인 정규화 가중치 알고리즘, 문서길이 정규화 가중치 알고리즘과 결합하여 질의를 확장하는 것이 정규화시키지 않고 단순히 문헌빈도와 역문헌빈도의 조합을 이용한 가중치 알고리즘과 결합했을 때 보다 평균 정확률 향상이 더 높게 나타났다. 또한 다양한 공기기반 유사도를 이용하여 질의확장을 한 결과 벡터모델과 신경망 모델에서 코사인 공기유사도에 기반하여 질의확장한 경우가 다른 공기유사도에 비해 더 좋은 성능을 보였다.

The author describes document delivery services and document usage patterns of domestic users based on usage statistical data about photocopying service of KINITI that the most important document delivery organization in Korea. And investigated ordering procedures of users, number of document processed and rejected in photocopying service, and delivery methods for users and so on. In FY 1996, number of document in photocopying service increased 2.4 percent in proportion to previous year.

This paper describes the results of a cost-effectiveness analysis on the usage of foreign scientific and technical journals. In this study, the measure of cost-effectiveness chosen is the Cost Per Use(CPU) of a journal article. The photocopy usage data and annual subscription costs of journals subscribed by Korea Institute of Science & Technology Information were used. The results of this study illustrate that distribution of subscription cost and photocopy usage, Cost Per Use(CPU) of each journal, CPU of each subject field, etc. 80 percent of the demand for the journal was met by 40 percent of total subscription cost. A relationship was found between subscription cost and photocopy usage, however, no relationship was found between subscription cost and CPU.

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.
