The structure and infrastructure of the Indian research literature were determined. A representative database of technical articles was extracted from the Science Citation Index/Social Science Citation Index (SCI/SSCI) [SCI. Certain data included herein are derived from the Science Citation Index/Social Science Citation Index prepared by the THOMSON SCIENTIFIC®, Inc. (Thomson®), Philadelphia, Pennsylvania, USA: ©Copyright THOMSON SCIENTIFIC® 2006. All rights reserved. [1]] for 2005, with each article containing at least one author with an India address. Document clustering was used to identify the main technical themes (core competencies) of Indian research. Aggregate India bibliometrics were also performed, emphasizing the value of collaborative research to India. A unique mapping approach was used to identify networks of organizations that published together, networks of organizations with common technical interests, and especially those organizations with common technical interests that did not co-publish extensively. Finally, trend analyses were performed using other year data from the SCI/SSCI to place the 2005 results in their proper historical context.  相似文献

The structure and infrastructure of Mexico's science and technology   总被引:1,自引:0,他引:1  
The structure and infrastructure of the Mexican technical literature was determined. A representative database of technical articles was extracted from the Science Citation Index for the year 2002, with each article containing at least one author with a Mexican address. Many different manual and statistical clustering methods were used to identify the structure of the technical literature (especially the science and technology core competencies). One of the pervasive technical topics identified from the clustering, thin films research, was analyzed further using bibliometrics, in order to identify the infrastructure of this technology.  相似文献

The structure and infrastructure of the Finnish research literature is determined. A representative database of technical articles was extracted from the Science Citation Index for the years 2003–2004, with each article containing at least one author with a Finnish address. Document clustering was used to identify the main technical themes (core competencies) of Finnish research. Four of the pervasive technical topics identified from the clustering (Wireless Networks and Mobile Communication, Signal Processing, Materials Science and Engineering, Chemistry) were analyzed further using bibliometrics, in order to identify the infrastructure of these research areas. Finally, the citation performance of Finnish research in the four pervasive technical topics above, and in other technical topics obtained by analysis of Abstract phrases, was compared to that of two Scandanavian countries with similar population and GDP, Norway and Denmark.  相似文献

This Research Note updates our 2006 and 2009 China/USA nanotechnology and nanoscience (NN) research output comparisons.A 2009 comparison of China/USA research publication outputs showed that China is about to overtake the USA in NN research output. As predicted by the extrapolated 2009 curve, China has passed USA in NN research publication output. This transition occurred in the 2008/2009 time frame, and if the 2011 results (taken at mid-2011) hold for the full year, will become quite pronounced (~ 20%).When specific sub-disciplines are examined, the differences between China and USA become more pronounced. For example, the 2009 paper presented the time trend for China/USA publications in nanocomposites, an important sub-discipline of NN. The updated nanocomposites curve has increased about twice the rate of the overall NN curve, and shows no sign of abating.The USA papers lead in the numbers of citations by all metrics considered, but the Chinese papers are showing significant improvement with time. Overall, the Chinese papers are cited very modestly, but there is a core of 'heavy hitters' that appears to be increasing substantially with time, and is increasingly making its presence known in the higher Impact Factor journals.  相似文献

This ‘country study’ analyses substantial samples of research papers by Brazilian authors drawn from two global databases. The approach and the findings may each be of interest. Our approach is to examine R&D outputs through bibliometrics (to identify key authors, institutions, journals, etc.) and text mining with taxonomy generation (to identify pervasive research thrusts). We extend prior country studies by providing for interactive data access and exploring military-relevant R&D information. The resulting publication activity profiles provide insight on Brazilian R&D strengths and investment strategies, and help identify opportunities for collaboration. Brazil, a nation of 190 million, evidences a substantial research enterprise, with major capabilities in the life and biomedical sciences, as well as the physical sciences. We benchmark research patterns and trends against several other countries. We find a large measure of international collaboration, particularly with the USA.  相似文献

Research in the field of financial crisis has generated a considerable amount of literature in the past, yet there has neither been any study to assess the contributions to the literature made by individuals or institutions, nor any to measure the impact of the articles and researchers. This study represents an attempt to: (1) investigate the major journals in publishing financial crisis research, (2) assess the contributions of individual researchers and institutions using the credited contribution approach and (3) measure the impact of individual publications and individual researchers on the financial crisis literature through citation analysis, based on the publications in Social Science Citation Index (SSCI) journals from 1990 to 2008. The findings provide a useful benchmark for assessing individual and institutional research productivity, and trends for future research and venues for publications are identified.  相似文献

The objective of this research work is to study the progress of research on technological uncertainties, social uncertainties and emerging markets and outline and identify the key disciplines, journals, articles and authors. For this the author studied the existing literature from the various fields in which technological uncertainties, social uncertainties and emerging markets research work have been published using ISI Web of Knowledge database. The paper finds that there is increasing research work on technological uncertainties, social uncertainties and emerging markets and the bibliographical search resulted in ninety-one documents written by one-hundred-sixty-one authors in eighty-four journals in seventy-two disciplines. The five major disciplines and their underlying journals are business and economics, agriculture, psychology, public administration, and environmental sciences and ecology accounting for majority of publications. In journals the most prolific, measured by number of articles published are Harvard Business Review, Social Science and Medicine, World Development, and Higher Education; and most influential, measured by the global citation received, are Harvard Business Review, Social Science and Medicine and Sociological Review. The top 10% of the journals are responsible for 23% of all publications but 85% of all global citations received. This highlights that despite the high, diverse and increasing number of journals; only few are dominating and shaping the research arena of technological uncertainties, social uncertainties and emerging markets. Further, in the ten most cited articles, no author appears more than once.  相似文献

Hounshell and Smith's Science and Corporate Strategy: DuPont R&D, 1902- 1980 is one of the most comprehensive business history books ever written. In addition, it highlights the important relationship between corporate strategy and R&D activities. The purpose of this current paper is to update the information on DuPont's R&D activities using secondary data and bibliometrics. Our findings are that DuPont underwent a series of dramatic shifts in their R&D efforts during the 1980s and into the 1990s. For example, there was a focus on life sciences, a concerted attempt to reduce R&D, and an endeavour to align R&D more with core businesses. Beyond the bibliometrics, we found that corporate performance and changes in the top management team may have precipitated these changes in R&D. The implications of such relationships are also discussed.  相似文献

A comparison was made of the research output literatures of India and China. Both bibliometric and computational linguistics approaches were used in the comparison. China has rapidly outpaced India in both volume and citation performance of publications. China's rapid publication growth rate over the past two decades is continuing, while India's is re-starting after a relatively dormant period of almost two decades.  相似文献

In the essays prepared by NAS for the first Outlook, current research in the natural sciences and technology were treated carefully and thoughtfully, but the social sciences were largely overlooked. To remedy this in the second Outlook, the Social Science Research Council was asked to prepare essays on the ways in which social science research can illuminate national problems or contribute to policy discussions. Six such essays describe continuing and developing research traditions on social problems such as aging and health.  相似文献

This paper presents measures of the research output of Australian economics departments. Our study covers the 640 academic staff at rank Lecturer and above in the 27 Australian universities with economics departments containing eight or more staff in April 2002. We construct publication measures based on journal articles, which can be compared with weighted publication measures, and citation measures, which can be compared with the publication measures. Our aim is to identify the robustness of rankings to the choice of method, as well as to highlight differences in focus of departments' research output. A striking feature of our measures is that the majority of economists in Australian university departments have done no research that has been published in a fairly long list of refereed journals over the last dozen years. They may publish in other outlets, but in any event their work is rarely cited. Thus, average research output is low because many academic economists in Australia do not view research as part of their job or, at least, suffer no penalty from failing to produce substantive evidence of research activity.  相似文献

ABSTRACT

The amalgamation of machine learning and big data has led to a revolution in data science with several influencing applications to various domains. To gain insights on the current research trends on machine learning for big data analytics, this study follows a bibliometric analysis methodology of citation data to review and quantitatively assess the explosion and impact of literature and research performance in this vibrant research area, which has witnessed rapid changes and rising interest in business, industry and academia. Using a variety of bibliometric measures and visualisation techniques, the paper examines and identifies several related issues including research productivity and directions, major contributors, publication trends and growth rates, citation and collaboration analysis, and others. The relevant bibliographic units for the study were collected from the Core Collection of the Web of Science bibliographic database. Nearly all the relevant publications prior to February 2018 were included in the analysis. The overwhelming productivity and wide-spread applications in several multidisciplinary domains have been revealed, with one-to-two ratio of journal to conference publications. Three countries (USA, China, India) are dominating the research output with more than two-thirds of the total productivity.  相似文献
