用文献计量数据解读中国和印度的科技发展

An Overview of China's and India's Science and Technology Literature

该文采用SCI/SSCI数据库,对通信联系人中至少含有一位印度/中国人的科技论文进行了文献计量学和计算语言学分析。依据对印度和中国科技文献单独分析的结果,深入地探讨了两国在科技领域的差异。借助不同的分析技术,包括影响因子分析、相关性图解以及文档聚类(传统聚类和模糊聚类),多角度地分析了中国和印度科技文献的基本学科结构体系(主要作者、研究单位等)与主要学科结构(学科重点以及学科重点之间的关系)。第一部分内容介绍了中国科技文献评估,第二部分阐述了印度科技文献评估,第三部分则为印度和中国科研成果的多角度比较。

The science and technology （S＆T） literatures of India and China were analyzed individually, then compared. Records having at least one author with an India or China address were retrieved from the Science Citation Index/Social Science Citation Index databases. Bibliometrics and computational linguistics analyses were performed on these retrieved records to generate the technical infrastructure （key authors, Centers of Excellence, etc） and technical structure （pervasive technical thrusts, relationships among thrusts） of the Chinese and Indian S＆T literatures, and to compare these literatures. A variety of analytical techniques were used to examine the infrastructure and technical structure from multiple perspectives, including factor analysis, correlation mapping, and document clustering （both traditional and fuzzy）. The summary results and conclusions from these studies were described. The first section of the paper presented an assessment of China＇s S＆T literature; the second section presented an assessment of India＇s S＆T literature; and the third section compared India＇s and China＇s research outputs from multiple perspectives.
