  • With the development of the economy and the improvement of living standards, the hot issues in the subject area have become the main research direction, and the mining of the hot issues in the subject currently has problems such as a large amount of data and a complex algorithm structure. Therefore, in response to this problem, this study proposes a method for extracting hot keywords in scientific journals based on the improved BERT model.It can also provide reference for researchers,and the research method improves the overall similarity measure of the ensemble,introducing compound keyword word density, combining word segmentation, word sense set distance, and density clustering to construct an improved BERT framework, establish a composite keyword heat analysis model based on I-BERT framework.Taking the 14420 articles published in 21 kinds of social science management periodicals collected by CNKI(China National Knowledge Infrastructure) in 2017-2019 as the experimental data, the superiority of the proposed method is verified by the data of word spacing, class spacing, extraction accuracy and recall of hot keywords. In the experimental process of this research, it can be found that the method proposed in this paper has a higher accuracy than other methods in extracting hot keywords, which can ensure the timeliness and accuracy of scientific journals in capturing hot topics in the discipline, and finally pass Use information technology to master popular key words.

  • 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.

  • Open access movement supports the principle that the published output of scientific research should be available to everyone without charge. The term open access is used in the broad context of the wider movement. To achieve the objectives of open access to scholarly journal literature, BOAI(Budapest Open Access Initiative) recommends using two complementary strategies: 'self-archiving' in institutional/disciplinary repositories and 'open access journals.' This study introduces the strategies of open access movements and analyzes the ways to help the cause of open access by academic stakeholders(i.e., researchers, librarians, universities, publishers, foundations, learned societies, and government) from the perspective of two BOAI strategies.

  • In this research, several ways of creating effective STI(Scientific & Technological Information) databases were suggested. We put emphasis on the selection of input data, while on the other was handled, such factors as standardization for data entry, data entry system, etc.. In order to decide priority of target data, the status of document delivery service was analyzed. The result shows that conference proceedings were given priority to academic journals. In case of journals, ranking in the number of documents requested at KORDIC (Korea R&D Information Center) and 16 Specialized Information Centers was compared with the ranking in citation frequency and impact factor, appeared at SCI.

  • Application of appropriate research methods has assumed an important role in knowledge accumulation endeavors in the scientific research community. The current study reported here summarizes how we used the empirical methods in IS research, what we need to improve in using empirical study as research methodology through the set of comprehensive research guideline. From the survey and review of seminal and classical research guidelines, we developed our own 28 checklist for research design, statistical analysis, and conclusion, which can be commonly applied to all articles that employ inferential statistical methods in IS research. Then, we critically evaluated the usage of empirical research methods in major IS journals by using the checklist, with the goal of improving the quality of academic papers. In this study, we scrutinized four major IS journals which published empirical papers from 1991 to 2000: MIS Quarterly, Journal of MIS, Information Systems Research, and Decision Sciences. As a result of intensive evaluation work, we could highlight many areas that are lagging and call for greater attention with regard to the proper usage of empirical study in IS research. The research findings in this study can be referred as checklist and guideline when IS researcher applies the empirical method.

  • It is important for scientific and technological papers to build citation DB and to offer service. The best example of citation DB is SCI that has been utilized in the world. The majority of Korean journals is not SCI journal, so it is impossible for the domestic journals to conduct quantitative analysis and performance evaluation. Korea Science Citation Index Service is the alternative service to get rid of the above problem. In the study, we carried out the user satisfaction survey for new vision of service from existing KSCI, correcting the result data. We evaluated the data and then derived the level of current system and the future improvement direction.

  • Open access journal has been one of the major academic information sources for researcherscharacterizing itself as free resource. Recently, as competition among academic information service provides becomes intense, open access journal also needs to enhance its service and expand information service function. This study aims to propose service features for next generation service of open access journals by analyzing service features of leading journal database services. As a result, four service features are suggested such as journal article components and multimedia features, expanded searching features, social service features and mobile information service.

  • Objectives: The purpose of this research was to identify the top 10 most-cited articles on the management of fractured or broken instruments and to perform a bibliometric analysis thereof. Materials and Methods: Published articles related to fractured instruments were screened from online databases, such as Web of Science, Scopus, PubMed, and ScienceDirect, and highly cited papers, with at least 50 citations since publication, were identified. The most-cited articles were selected and analysed with regard to publication title, authorship, the journal of publication, year, institution, country of origin, article type, and number of citations. Results: The top 10 most-cited articles were from various journals. Most were published in the Journal of Endodontics, followed by the International Endodontic Journal, and Dental Traumatology. The leading countries were Australia, Israel, Switzerland, the USA, and Germany, and the leading institution was the University of Melbourne. The majority of articles among the top 10 articles were clinical research studies (n = 8), followed by a basic research article and a non-systematic review article. Conclusions: This bibliometric analysis revealed interesting information about scientific progress in endodontics regarding fractured instruments. Overall, clinical research studies and basic research articles published in high-impact endodontic journals had the highest citation rates.
