From 1996, Some universities tried to reform the educational systems in Korea. Almost all departments of university except some departments are integrated In large subjects. humanities, social sciences ect. This study is on the relationship between the university education and a science, the Library and Information science position, the merits and demerits of the reformated educational system and it tries to suggest the educational direction of the library and information science.

This study examined the relative retrieval effectiveness after relevance feedback between two systems (Title/Abstract and Full-text) using four different sets of relevance judgment. Four relevance levels (not relevant, marginally relevant, relevant, highly relevant) are also used, each of which is determined by referees giving a relevance score to documents. This study also investigated how much the average precision was improved after relevance feedback when "marginally relevant" documents are included in the relevant class with the Title/Abstract system, and with the Full-text retrieval system as well. It is found that the Title/Abstract system benefited from relevance feedback with the marginally relevant documents. In case of the Title/Abstract system, the higher percentage of improvement was consistently obtained when including the marginally relevant documents in the relevance class, however the result was vice versa in case of the Full-text retrieval system. It implied that the marginally relevant documents in the relevant class had caused noises in the Full-text retrieval system.

The purpose of this study is to investigate the research trends of library and information science in Korea by means of the subject analysis of the Korean journal articles published during the last sixty years and by means of the ciation analysis of the literatures cited in the journal articles. The results of this study are as follows. First, the subjects of the journal articles are difference from the articles by publication period. The core subjects of the research have been changed over the years. Second, the subjects of library and information science literatures in foreign languages cited in the journal articles are difference from the literatures by citation period and by literature age. Third, the subjects of other disciplinary literatures in foreign langauges cited in the journal articles is difference from the literatures by citation period and by literature age. Fourth, although the half-life of library and information science literatures cited in the journal articles is difference from the literatures by subject, the half-life of the literatures of this discipline is 10-year.

Because it is difficult on existing document retrieval systems to visualize the search result, search results show document titles and short summaries of the parts that include the search keywords. If the result list is long, it is difficult to examine all the documents at once and to find a relation among them. This study uses clustering to classify similar documents into groups to make it easy to grasp the relations among the searched documents. Also, this study proposes a two-level visualization algorithm such that, first, the center of clusters is projected to low-dimensional space by using multi-dimensional scaling to help searchers grasp the relation among clusters at a glance, and second, individual documents are drawn in low-dimensional space based on the center of clusters using the orbital model as a basis to easily confirm similarities among individual documents. This study is tested on the benchmark data and the real data, and it shows that it is possible to visualize search results in real time.

The objective of this study is to excavate the current critical issues and suggest the future direction of the Library and Information Sciences(LIS) education. To do so, this research conducted a thorough comparative study of LIS eduction in Korea, U.S.A., and Australia, and the extensive research of the iSchool(Information School) movement currently involving 33 universities all around the world started with the initiative in U.S.A. Specifically, the study investigated the changes and the essence of LIS education and research trends by reviewing and analyzing comparatively the prior domestic and overseas research. Then, it examined the current characteristics of the LIS curricula in Korea, U.S.A., and Australia and performed the inter-country analysis. Finally, the study concludes with suggestions of the future of the LIS education and research directions through an in-depth case research of the iSchool movement spreading out rapidly all over the world.

With development in computing and networking technologies, national supports and attention for building digital library, which is to overcome the limits of time and location in using information resources, is increasing. To accomplish the main goal of digital library that is to freely share and transfer information on network, the importance of standardization in developing electronic document is increasing. Now several tools to develop electronic document, which will be used in digital library, are developed for electronic document used on WWW. But none of them has absolute advantages to other formats. Those tools, that is, have comparative advantages and disadvantages for making electronic documents. Through reviewing features and analyzing comparative advantage and disadvantage of SGML, HTML, and PDF, which will be used to develop electronic documents in digital libraries, this study focuses on their comparative advantages and disadvantages. With doing it, this study propose relevant type of electronic document formats to the types of information resources.

This study aimed to investigate key research areas in the field of Library and Information Science (LIS) by analyzing trends and identifying emerging topics. To facilitate the research, a collection of 40,897 author keywords from 11,252 papers published in the past 30 years (1993-2022) in five journals was gathered. In addition, keyword analysis, as well as Principal Component Analysis (PCA) and correlation analysis were conducted, utilizing variables such as the number of articles, number of authors, ratio of co-authored papers, and cited counts. The findings of the study suggest that two topics are likely to develop as promising research areas in LIS in the future: machine learning/algorithm and research impact. Furthermore, it is anticipated that future research will focus on topics such as social media and big data, natural language processing, research trends, and research assessment, as they are expected to emerge as prominent areas of study.

This study attempted to explore the characteristics of knowledge communication and investigate important research topics and key authors by analyzing major academic papers in the field of LIS in Korea for five years from 2018 to 2022. The research method collected and analyzed papers published for five years in four key journals in the field of domestic Library and Information Science from the Korean Citation Index (KCI) database. The paper was selected to extract the author data of the paper and the data of the reference, and network visualization was performed by conducting literature co-citation analysis and author co-citation analysis using Netminer. As a result of the analysis, it was possible to derive a pair of co-citations between authors, and it was confirmed that it is important to include multiple authors in the intellectual structure analysis in the academic field through co-citation frequency analysis among researchers. The literature confirmed the correlation between the topics of the paper, and it was found that research related to Library and Information Science was centered on the topics of library, digital, user, service, and data.

The purpose of this study is to verify if there is any difference on researchers' language preference for citing documents in different subject fields. 8 scientific journals were selected one of each from 8 main categories, given by National Research Foundation of Korea. Five variables including the rate of citing domestic and foreign documents for each journals were choose, and the differences on language preference among researchers of different subject fields were checked by implementing ANOVA. As a result, there are some differences on language preference, in terms of the average number and percentage of foreign documents, among researchers, based on their subject background. It also found that 8 subject categories divided into 4 small clusters.
