【摘要】：[目的 /意义]运用文本分析与可视化等方法绘制基本科学指标数据库(Essential Science Indicators,简称ESI)研究前沿的科学全景图谱,在此基础上绘制全球研究前沿视野下的纳米研究前沿图谱,分析中国在世界纳米前沿的科研表现。[方法 /过程]计算研究前沿间关联关系,利用OpenOrd布局算法可视化科学图谱,并根据图谱中研究前沿的位置关系自动识别研究前沿群。选取含纳米文章超过60%的研究前沿,结合专家判读绘制纳米研究前沿图谱。[结果 /结论]研究表明,科学图谱揭示的科学结构与作者先前的研究成果和业界已有科学图谱的分布较为一致,能有效揭示ESI研究前沿数据隐含的科学结构特征,反映科学前沿分布情况。以世界纳米前沿全貌图为基图,叠加中美在各研究前沿的论文份额,对比分析了中国和美国在世界纳米前沿上优势及发展重心的差异,结合专家研判给出对策建议,助力纳米领域的发展趋势研究,取得了实际应用价值。
[Abstract]:[objective / significance] to draw the scientific panoramic map of the research frontiers of basic scientific index database, including text analysis and visualization, on the basis of which the frontiers of nanometer research are drawn under the vision of the global research frontier. Analysis of China's scientific research performance in the world's nanometer frontier. [method / process] calculate and study the relationship between frontiers, visualize the scientific map by using OpenOrd layout algorithm, and automatically identify the frontier groups according to the position relation of the research frontier in the map. Selecting more than 60% of the research frontier of nanometer articles and combining with expert interpretation to draw the frontier map of nano research. [results / conclusions] the research shows that the scientific structure revealed by the scientific map is consistent with the distribution of the author's previous research results and the existing scientific maps in the industry, and it can effectively reveal the implied scientific structural characteristics of the ESI research frontier data. It reflects the distribution of scientific frontier. Based on the whole picture of the world's nanometer frontier, this paper overlay the share of papers of China and the United States in each research frontier, compares and analyzes the differences between China and the United States in the advantage and development center of development in the world's nanometer frontier, and puts forward some countermeasures and suggestions in combination with the study of experts. The research on the development trend of nano-field has gained practical application value.
