文章以Web of Science中收录的文献数据为分析对象,以计算机科学领域为例,验证国际合作是否能提高科学研究的影响力。为了检验国家数量与被引频次之间的相关性,开展了相关性分析和比较分析,并且分析了合作网络以了解各个国家所发挥的不同作用和影响。结果表明,国际合作论文的被引频次总体上高于国内作者的论文,但国家数量与被引频次之间仅存在弱相关关系。我国在2007—2009年期间共与65个国家开展了合作研究,其中19个国家在提高平均被引频次方面发挥了重要作用。
The article takes the literature data collected in Web of Science as the analysis object, and takes computer science as an example to verify whether international cooperation can improve the influence of scientific research. In order to examine the correlation between the number of countries and their cited frequency, a correlation analysis and a comparative analysis were carried out, and the cooperation network was analyzed to understand the different roles and impacts of each country. The results show that the number of cited citations of international collaborative papers is generally higher than that of domestic authors, but there is only a weak correlation between the number of countries and the cited citations. In 2007-2009, my country conducted a collaborative study with 65 countries, of which 19 countries played an important role in raising the average number of citations per second.
