  • Recently, the valuation of patented technology has been greatly emphasized, and patent citation has been accepted as a very useful index of this technology. In this study, we performed correlation analyses between the patent citation counts and 17 explanatory variables of morphological, technological, and conceptual factors with a test dataset of U.S. patents in five subject fields. Seven variables having 5% or more standardized variances($r^2$) with patent citation counts were identified; number of pages, number of claims, reference-average-citation rate, patent increase/decrease rate, strength of bibliographic coupling, co-citation counts and document similarity. The result of the ANOVA test shows that the mean values of these variables vary among most subject fields.

  • In order to produce information the author usually reference other authors' work. A citation index leads users to papers by citations. Citations lead the user to desired information. In this paper, KSCI(Korea Science Citation Index) which defines the relationships between citing documents and cited documents has been constructed. KSCI System is to solve problems for recursive retrieval in ISI's SCI(Science Citation Index) Path Encoding Indexing technique was used to solve the problems. From the analysis of data, this system has efficiency about 8.98% in the aspect of data storage. In the aspect of retrieval, there was efficiency between citing documents and cited documents, especially there was over 40% of efficiency in the retrieval of cited documents. It is concluded that suggested KSCI system will provide efficient storage and retrieval system.

  • The purpose of this article is to examine the research trends of 'bibliography' in Korea. By utilizing citation analysis methods, total 1,321 cited references of the 51 articles published by ${\ulcorner}Journal of the Institute of Bibliography{$\lrcorner}$ in 2000 and 2001 are analysed. This analysis is focused on an article's subjects and authors'occupations, the numbers and journal categories of its cited references. Also, this study observes the nationalities and languages of cited references and various items related to authors of cited references. The most of findings of this study are similar to the previous studies. However, it could find that there are minor differences from the existing literatures, in respect to subject areas, the number of cited references and the forms of cited references. In conclusion, this study recommends that bibliographers's collaborative works with related fields such as history and library and information science need to be strengthened, and that qualitative apaches as well as citation analysis methods might be beneficial for further expansion of academic scope of 'bibliography'.

  • The valuation of patented technology has been recently emphasized, and the patent citation is known as an important factor. This study performed a generalized linear model to find variables that effect the patent citation. We classified 13 variables as morphological, technological and conceptual factors and used them to find out effective variables in 14 medical devices classification. Through the empirical study, we found seven effective variables (assignee nationality, assignee character, the number of inventors, the number of application countries, the number of IPC, the number of references, the strength of bibliographic coupling). In order to apply to Korean industry, this study has significance that provides basic research to citation analysis model.

  • Recently, the valuation of research papers has been greatly emphasized, and their citation has been accepted as a very useful indicator. In this study, we performed correlation analyses between the paper citation counts and 11 explanatory variables of morphological and conceptual factors with a test dataset of the papers of 11 journals in library and information science. The analysis results of the correlations show that only the document similarity has 5% or more standardized variances(r2) with paper citation counts and the document similarity with citation counts get higher as the variable value increases.

  • There have been little comprehensive research for studying impact of foreign journals on Korean scientists. The main reason for this is because there was no extensive citation index database of domestic journals for analysis. Korea Institute of Science and Technology Information (KISTI) built the Korea Science Citation Database (KSCD), and have provided Korea Science Citation Index (KSCI) and Korea Journal Citation Reports (KJCR) services. In this article, citing behavior of Korean scientists on foreign journals was examined by using KSCD that covers Korean core journals. This research covers (1) analysis of foreign document types cited, (2) analysis of citation counts of foreign journals by subject and the ratio of citing different disciplines, (3) analysis of language and country of foreign documents cited, (4) analysis of publishers of journals and whether or not journals are listed on global citation index services and (5) analysis for current situation of subscribing to foreign electronic journals in Korea. The results of this research would be useful for establishing strategies for licensing foreign electronic journals and for information services. From this research, immediacy citation rate (average 1.46%), peak-time (average 3.9 years) and half-life (average 8 years) of cited foreign journals were identified. It was also found that Korean scientistis tend to cite journals covered in SCI(E) or SCOPUS, and 90% of cited foreign journals have been licensed by institutions in Korea.

  • Industrial convergence is manifested in various forms by various drivers, and understanding and categorizing the direction of convergence according to the factors in which the convergence occurs is an essential requirement for the establishment of a company's customized convergence strategy and the government's corporate support policy. In this study, the type of convergence is analyzed from the perspective of knowledge flow between heterogeneous technologies, and for this purpose, the result of topic modeling of the text information of the patent and the citation information of the corresponding patent allocated for each topic are used. The methodology presented through case studies in the medical device field is verified. Through the proposed methodology, companies can predict the flow of convergence and use it as decision-making data to create new business opportunities. It is expected that the government and research institutions will be usefully used as basic data for policy preparation.

  • 경제의 패러다임이 지식의 확산과 공유가 경제 성장의 주요한 요소로 대두되는 지식기반경제로 변화하게 되고, 융합 기술(fusion technology)의 중요성에 대한 인식으로부터 학제간(inter-disciplinary) 연구나 기술개발이 활발해지면서, 각 산업이 타산업과 맺고 있는 특정한 연계구조에 대한 분석은 정부의 기술정책이나 기업의 기술전략 수립에 필수적인 것으로 받아들여지고 있다. 특히 산업간 지식흐름의 구조를 파악하는 것은 산업간 협력(collaboration)의 형태나 파급효과에 대한 분석뿐만 아니라 기술 혁신을 촉진하기위한 혁신 클러스터(innovative cluster) 형성의 기초를 제공하는 것이라 하겠다. 따라서 본 연구는 기술집약적 장비에 체화된 유형자원의 간접적 지식 확산이 아닌, 특허 인용의 명백한 지식 흐름을 활용하여 한국 제조업의 지식 흐름 구조를 분석하고 이를 토대로 클러스터를 나누는 것을 목적으로 한다. 이를 위하여 특허 인용 정보가 존재하는 미국특허청(USPTO)의 자료를 이용하며, 여기에서 도출된 한국 특허의 인용관계를 통해 한국 제조업의 네트워크 및 클러스터를 생성하였다. 즉, 특허 분류를 산업 분류에 매칭(matching)시킴으로써, 특허의 인용관계를 각 특허가 속한 산업간의 지식흐름으로 변환하여 산업간 연계 구조를 파악하고 이를 토대로 한국 산업의 지식 클러스터를 생성함으로써 클러스터간 지식 흐름을 분석하고, 각 클러스터의 기술적 특성을 제시하였다. 본 연구는 한국 산업의 지식흐름을 미국특허청에 출원된 한국 특허를 활용하여 분석했다는 점에서 제기될 수 있는 해외 기술 시장으로의 전략적 차원의 출원에 의한 자료의 편중성문제와 지식흐름의 절대량이 아닌 상대량을 통해 클러스터링함으로써 발생될 수 있는 자료 활용의 한계점을 지니고 있다. 그러나 비체화 지식의 흐름을 특허인용관계를 통해 실증적으로 분석하고, 이를 통해 클러스터를 나누어 산업간 연계구조와 기간에 따른 변화 양상을 조명하며, 각 클러스터의 특성을 다양한 지표(indicators)로부터 설명했다는 데에서 의의를 찾을 수 있다. 본 연구의 결과는 기술혁신을 위한 국가 차원의 산업정책이나 기술개발과 관련한 기업의 기술전략에 활용될 수 있을 것이다.

  • It is meaningful to develop the scholarly digital archives in a respect that it could preserve the research papers using digital media. The scholarly digital archives provide scientists with the information source with which scientists could actively accomplish research. This study measured based on the citation analysis to what extent PMC, which is life science scholarly digital archives, has an effect on the scholarly communication in the same subject field. The findings are as follows. First, the three citation indicators, impact factor, immediacy index, and half-life, have no remarkable difference in between pre and post-digital archives era. Second, there were more cases that the major citation indicators increased rather than ones decreased with the appearance of the scholarly digital archives, as a result of ranking the scholarly journals after classifying according to subjects.
