Although domestic research funding organizations require patented technologies as an outcome of financial aids, they have much difficulty in evaluating qualitative value of the patented technology due to lack of systematic methods. Especially, because citation data is not essential to patent application in Korea, it is very difficult to evaluate a patent using the incomplete citation data. This study proposes a method for evaluating technology importance of a patent when there is no or insufficient citation data in patents. The technology importance of a patent can be evaluated objectively and quantitatively by the proposed method which consists of 5 steps such as selection of a target patent, collection of related patents, preparation of key word vector, clustering patents, and technological importance assessment. The method was applied to a patent on 'user identification method for payment using mobile terminal' in order to evaluate technology importance and demonstrate how the method works.

This paper aims to explore the citation patterns of conference papers in 'Information Science' discipline and to analze impacts of various cited works-related factors on future citations of conference papers. Existing bibliometric studies has investigated citation patterns and the statistical relations between a variety of bibliographic factors and the future citations of literature. However, the attentions have been focused largely on journal articles, and the bibliometric studies targeting conference papers are still in an infant stage. Therefore, this study, which is based on 1,904 conference papers in 'Information Science' field, examined several citation patterns and the contributions of the factors about cited works - the number of cited works, type of cited works, citation rates and ages of cited works at the time of being cited and the rate of self-citedness - to the future citation of the citing target articles. The data source of this study including the properties of target articles and cited works and citation rates of target articles was Scopus. As the results, 53% and 29% of the cited works were conference papers and journal articles, respectively. 14% of them are non-traditional types such as web pages, technical reports, patent, etc. More than 60% of the cited works were 5 years old or less. Among several factors considered in this paper, the number of conference papers and the number of non-traditional types of works are the most contributing factors on the citation rates of target articles. The recency of the cited works is also significant contributor on the citation rates of target articles. That is, the target articles citing more conference papers and non-traditonal types of works earned more citations. The target articles citing recent works also earned more citations.

The study investigated the citation indicators and the citation analysis data developed in the KoMCI(Korean Medical Citation Index) project. With the full understanding of the current level of citation rates of Korean medical journals by Korean medical journals. and of the characteristics and problems associated with the KoMCI citation indicators, it is possible to further develop or modify citation indicators which will better represent the citation patterns of Korean medical journals. The highest impact factor reported in the KoMCI 2000 : Korean Medical Journal Citation Reports, which covered 69 Korean medical journals published in 2000 is 0.424 and the average is 0.182. It is because only 8.5% of references cited in Korean medical journal articles is to the Korean journal articles, The journal self-citation rates are very high (usually higher than 50%) due to the fact that there are only a few Korean journals published in the same subject area. The KoMCI impact factors of two Korean SCI journals for which SCI JCR reported the SCI 2000 impact factors are about 1/3 of the SCI impact factors. It is because SCI is based on the citations received from 5,900 journals whereas KoMCI is from 69 journals.

The bibliometric analysis is widely used for understanding research domains, trends, and knowledge structures in a particular field. The analysis has majorly been used in the field of information science, and it is currently applied to other academic fields. This paper describes the analysis of academic literatures for classifying research domains and for suggesting empty research areas in the telecommunications policy. The application software is developed for retrieving Thomson Reuters' Web of Knowledge (WoK) data via web services. It also used for conducting text mining analysis from contents and citations of publications. We used three text mining techniques: the Keyword Extraction Algorithm (KEA) analysis, the co-occurrence analysis, and the citation analysis. Also, R software is used for visualizing the term frequencies and the co-occurrence network among publications. We found that policies related to social communication services, the distribution of telecommunications infrastructures, and more practical and data-driven analysis researches are conducted in a recent decade. The citation analysis results presented that the publications are generally received citations, but most of them did not receive high citations in the telecommunications policy. However, although recent publications did not receive high citations, the productivity of papers in terms of citations was increased in recent ten years compared to the researches before 2004. Also, the distribution methods of infrastructures, and the inequity and gap appeared as topics in important references. We proposed the necessity of new research domains since the analysis results implies that the decrease of political approaches for technical problems is an issue in past researches. Also, insufficient researches on policies for new technologies exist in the field of telecommunications. This research is significant in regard to the first bibliometric analysis with abstracts and citation data in telecommunications as well as the development of software which has functions of web services and text mining techniques. Further research will be conducted with Big Data techniques and more text mining techniques.

Data journals and data papers have grown and considered an important scholarly practice in the paradigm of open science in the context of data sharing and data reuse. This study investigates a total of 713 data papers published in Scientific Data in terms of author, citation, and subject areas. The findings of the study show that the subject areas of core authors are found as the areas of Biotechnology and Physics. An average number of co-authors is 12 and the patterns of co-authorship are recognized as several closed sub-networks. In terms of citation status, the subject areas of cited publications are highly similar to the areas of data paper authors. However, the citation analysis indicates that there are considerable citations on the journals specialized on methodology. The network with authors' keywords identifies more detailed areas such as marine ecology, cancer, genome, database, and temperature. This result indicates that biology oriented-subjects are primary areas in the journal although Scientific Data is categorized in multidisciplinary science in Web of Science database.

The citation analysis is not applied to group measurements but to individual papers finding their impact factors among citation chains which are created by tracing citing-cited relationship between any two papers in data set. The individual impact factor is measured by adding each value derived from citation chain. Each paper's impact factor index is calculated by adding the values of each index by direct citing-cited relationship, and the values of each impact factor made by indirectly influencing to the papers in the citation chain. The research introduces a grace period, in which the system holds the papers not cited by other papers yet, but are expected to be cited within this period. Eventually not cited papers after the grace period would be eliminated by the system. The experiment suggests a reasonable database in which the highly influenced papers are gathered, and could be serviced in stead of buying databases filled with worthless not-cited-papers.

Bibliometric analysis for research performance evaluation can generate erroneous assessments for various reasons. Application of the same evaluation metric to different domains, for instance, can produce unfair evaluation results, while analysis based on incomplete data can lead to incorrect conclusions. This study examines bibliometric data of library and information science (LIS) research in Korea to investigate whether research performance should be evaluated in a uniform manner in multi-disciplinary fields such as LIS and how data incompleteness can affect the bibliometric assessment outcomes. The initial analysis of our study data, which consisted of 4,350 citations to 1,986 domestic papers published between 2001 and 2010 by 163 LIS faculty members in Korea, showed an anomalous citation pattern caused by data incompleteness, which was addressed via data projection based on past citation trends. The subsequent analysis of augmented study data revealed ample evidence of bibliometric pattern differences across subject areas. In addition to highlighting the need for a subject-specific assessment of research performance, the study demonstrated the importance of rigorous analysis and careful interpretation of bibliometric data by identifying and compensating for deficiencies in the data source, examining per capita as well as overall statistics, and considering various facets of research in order to interpret what the numbers reflect rather than merely taking them at face value as quantitative measures of research performance.

The authority and reputation of a medical journal is based on the number of received citations. Korean Medical Citation Index [KoMCI] provides information about citations of Korean medical journals since 2002. All six issues of KoMCI [from 2000 to 2005] were used for analysis. Citations, impact factor, and their changes were evaluated. We compared the data of Journal of Korean Neurosurgical Society[JKNS] with other Korean medical journals. The impact factor[IF] of 2005 maintained increased value since 2004, although the impact factor excluding self citation[ZIF] returned previous low value. Improvement in proportion of Korean citations and in proportions of non-self received citations were encouraging changes. Although there were some improvements, the status of JKNS with respect to ZIF is still behind other Korean medical journals selected for comparison. Improvement of the status of JKNS by aid of KoMCI and enhanced reputation of KoMCI by its positive influence on JKNS or other Korean medical journals will be beneficial to members and medical societies of Korea.

Author co-citation analysis with 20 authors from Korean Nutrition Literature were executed. The purpose of this study is to examine the meaning of bibliographic phenomena in Korean literature by co-citation and to approach the intellectural structure of nutrition field in view of multidimensional space. The analysis assumes that the more two author are cited together, the closer the relationship between them. The raw data are co-citation counts from the Korean Journal of Nutrition over the period 1986~1987. The resulting map shows (1) identifiable author groups of nutrition, (2) locations of these groups with respect to each other, (3) the degree of centrality and peripherality of author within groups, (4) the relationship between domestic authors and foreign authors.
