This study employs the method of direct citation to analyze and compare the interdisciplinary characteristics of the two disciplines
of library science and information science during the period of 1978–2007. Based on the research generated by five library
science journals and five information science journals, library science researchers tend to cite publications from library
and information science (LIS), education, business/management, sociology, and psychology, while researchers of information
science tend to cite more publications from LIS, general science, computer science, technology, and medicine. This means that
the disciplines with larger contributions to library science are almost entirely different from those contributing to information
science. In addition, researchers of library science frequently cite publications from LIS; the rate is as high as 65.61%,
which is much higher than the rate for information science, 49.50%. However, a decreasing trend in the percentage of LIS in
library science indicates that library science researchers tend to cite more publications from non-LIS disciplines. A rising
trend in the proportion of references to education sources is reported for library science articles, while a rising trend
in the proportion of references to computer science sources has been found for information science articles. In addition,
this study applies an interdisciplinary indicator, Brillouin’s Index, to measurement of the degree of interdisciplinarity.
The results confirm that the trend toward interdisciplinarity in both information science and library science has risen over
the years, although the degree of interdisciplinarity in information science is higher than that in library science. 相似文献

This article reports findings from the study of the international contribution to the system of library and information science
communication in Poland in the years 2003–2005. The sample consists of articles published both in selected journals and collective
works. Two important dimensions determining the internationalization of local scholarly communication are considered: direct
contribution (foreign authors’ articles and papers and their translations published in Poland) and indirect contribution (citedness
of foreign authors’ documents in articles and papers published in Poland). Bibliographic data about the geographical distribution
and affiliation of foreign authors are gathered and analyzed. Furthermore, the findings of citation analysis are presented
to determine the percentage share of citations received by foreign documents as well as to find out what is the structure
of such citations regarding the language and form, which thematic areas are most replete with such citations and which foreign
journals are most cited in Poland. 相似文献

Does the arXiv lead to higher citations and reduced publisher downloads for mathematics articles? 总被引:1,自引:0,他引:1
An analysis of 2, 765 articles published in four math journals from 1997 to 2005 indicate that articles deposited in the arXiv
received 35% more citations on average than non-deposited articles (an advantage of about 1.1 citations per article), and
that this difference was most pronounced for highly-cited articles. Open Access, Early View, and Quality Differential were
examined as three non-exclusive postulates for explaining the citation advantage. There was little support for a universal
Open Access explanation, and no empirical support for Early View. There was some inferential support for a Quality Differential
brought about by more highly-citable articles being deposited in the arXiv. In spite of their citation advantage, arXiv-deposited
articles received 23% fewer downloads from the publisher’s website (about 10 fewer downloads per article) in all but the most
recent two years after publication. The data suggest that arXiv and the publisher’s website may be fulfilling distinct functional
needs of the reader. 相似文献

A co-word analysis of library and information science in China 总被引:1,自引:0,他引:1
This study aims to reveal the intellectual structure of Library and Information Science (LIS) in China during the period 2008–2012 utilizing co-word analysis. The status and trends of LIS in China are achieved by measuring the correlation coefficient of selected keywords extracted from relevant journals in the Chinese Journal Full-Text Database. In co-word analysis, multivariate statistical analysis and social network analysis are applied to obtain 13 clusters of keywords, a two-dimensional map, centrality and density of clusters, a strategic diagram and a relation network. Based on these results, the following conclusions can be drawn: (i) LIS in China has some established and well-developed research topics; (ii) a few emerging topics have a great potential for development; and (iii), the research topics in this LIS field are largely decentralized as a whole, where there are many marginal and immature topics. 相似文献

The article processing charge (APC) provides economic sustainability for scientific journals that publish in open access (OA). In this work, documents published in OA between 2012 and 2016 by authors with Brazilian affiliation are identified, the profile of these publications is analyzed and the cost of APC is estimated. In order to do so, data from 930 journals and 63,847 documents were collected from the Web of Science Core Collection. It was found that 59% of these documents were published in journals that charge APC. The total expenditures for the 5-year period were estimated at approximately USD 36 million, the weighted average cost per document at USD 957.75 and the average cost per journal at USD 1492.27. The profile of these publications shows that journals indexed by SciELO represent 67% of the 63,847 documents. The use of mega-journals increased over the period, which implies an increase in expenditure in publications, since the average APC per journal was USD 2059.77. It was observed that the OA Brazilian scientific production is characterized by an endogenic profile and has a preference for the Gold road with APC. These results suggest that policies for funding charges are required to stimulate a more international attitude. 相似文献

Most biomedical journals accept original research articles in the form of “brief reports”. We compared the citations to full papers versus brief reports in a sample of journals on Infectious Diseases, Clinical Microbiology, and Antimicrobial Agents. Brief reports were cited less often than full-size articles [regression coefficient: 10.94 (95 % CI: 5.19, 16.69)] even after adjustment for the journal’s impact factor. Our findings may influence decisions of editors and authors regarding brief reports. 相似文献

This paper aims to reveal the relationship and structure of library and information science (LIS) journals in China. 24 core LIS journals in China are selected and the relevant data of journal co-citation are retrieved from Chinese Journal Full-Text Database constructed by China National Knowledge Infrastructure during the period of 1999–2009. By calculating mean co-citation frequencies and correlation coefficients, we find that there is a strong relationship among LIS journals in China. Utilizing the methods of cluster analysis, multidimensional scaling analysis and factor analysis, we analyze the data of journal co-citation. LIS journals in China are divided into four clusters. The relatedness among journals is shown manifestly through their locations in the two-dimensional map. A three-factor solution is obtained with the factor loading of each journal. Finally, we interpret and discuss the results to get some conclusions and also expect to describe the network characters of journal co-citation in future research. 相似文献

This study assessed research patterns and trends of library and information science (LIS) in Korea by applying bibliometric analysis to 159 Korean LIS professors?? 2,401 peer-reviewed publications published between 2001 and 2010. Bibliometric analysis of publication data found an increasing trend for collaboration, robust publication patterns, increasing number of international publications, and internationalization of LIS in Korea. The maturation and internalization of LIS research was evidenced in increased number of publications in high impact journals (e.g., SSI, SSCI), growing participation in leading international conferences (e.g., ASIST, TREC), increasing proportion of Korean LIS faculty with international degrees, and high publication rates by professors with international degrees. Though limited in its evaluative power without citation data, publication data can be a rich source for bibliometric analysis as this study has shown. The analysis of publication patterns conducted by the study, which is a first step in our aim to establish a multi-faceted approach for assessing the impact of scholarly work, will be followed up in a future study, where the question of quantity versus quality will be examined by comparing publication counts with citation counts. 相似文献

Given that many frontiers and hotspots of science and technology are emerging from interdisciplines, the accurate identification and forecasting of interdisciplinary topics has become increasingly significant. Existing methods of interdisciplinary topic identification have their respective application fields, and each identification result can help researchers acquire partial characteristics of interdisciplinary topics. This paper offers an integrated method for identifying and predicting interdisciplinary topics from scientific literature. It integrates various methods, including co-occurrence networks analysis, high-TI terms analysis and burst detection, and offers an overall perspective into interdisciplinary topic identification. The results of the different methods are mutually confirmed and complemented, further overviewing the characteristics of the interdisciplinary field and highlighting the importance or potential of interdisciplinary topics. In this study, Information Science and Library Science is selected as a case study. The research has clearly shown that more accurate and comprehensive results can be achieved for interdisciplinary topic identification and prediction by employing this integrated method. Further, the integration of different methods has promising potential for application in knowledge discovery and scientific measurement in the future. 相似文献

This paper aims to identify the collaboration pattern and network structure of the coauthorship network of library and information science (LIS) in China. Using data from 18 core source LIS journals in China covering 6 years, we construct the LIS coauthorship network. We analyze the network from both macro and micro perspectives and identify some key features of this network: this network is a small-world network, and follows the scale-free character. In the micro-level, we calculate each author’s centrality values and compare them with citation counts. We find that centrality rankings are highly correlated with citation rankings. We also discuss the limitation of current centrality measures for coauthorship network analysis. 相似文献

Two commonly used ideas in the development of citation-based research performance indicators are the idea of normalizing citation counts based on a field classification scheme and the idea of recursive citation weighing (like in PageRank-inspired indicators). We combine these two ideas in a single indicator, referred to as the recursive mean normalized citation score indicator, and we study the validity of this indicator. Our empirical analysis shows that the proposed indicator is highly sensitive to the field classification scheme that is used. The indicator also has a strong tendency to reinforce biases caused by the classification scheme. Based on these observations, we advise against the use of indicators in which the idea of normalization based on a field classification scheme and the idea of recursive citation weighing are combined. 相似文献

A series of techniques based on bibliometric clustering and mapping for scientometrics analysis was implemented in a software toolkit called CATAR for free use. Application of the toolkit to the field of library and information science (LIS) based on journal clustering for subfield identification and analysis to suggest a proper set of LIS journals for research evaluation is described. Two sets of data from Web of Science in the Information Science & Library Science (IS&LS) subject category of Journal Citation Reports were analyzed: one ranges from year 2000 to 2004, the other from 2005 to 2009. The clustering results in graphic dendrograms and multi-dimensional scaling maps from both datasets consistently show that some IS&LS journals clustered in the management information systems subfield are distant from the other journals in terms of their intellectual base. Additionally, the cluster characteristics analyzed based on a diversity index reveals the regional characteristics for some identified subfields. Since journal classification has become a high-stake issue that affects the evaluation of scholars and universities in some East Asian countries, both cases (isolation in intellectual base and regionalism in national interest) should be taken into consideration when developing research evaluation in LIS based on journal classification and ranking for the evaluation to be fairly implemented without biasing future LIS research. 相似文献
