【摘要】：[目的 /意義]運用文本分析與可視化等方法繪制基本科學指標數(shù)據(jù)庫(Essential Science Indicators,簡稱ESI)研究前沿的科學全景圖譜,在此基礎(chǔ)上繪制全球研究前沿視野下的納米研究前沿圖譜,分析中國在世界納米前沿的科研表現(xiàn)。[方法 /過程]計算研究前沿間關(guān)聯(lián)關(guān)系,利用OpenOrd布局算法可視化科學圖譜,并根據(jù)圖譜中研究前沿的位置關(guān)系自動識別研究前沿群。選取含納米文章超過60%的研究前沿,結(jié)合專家判讀繪制納米研究前沿圖譜。[結(jié)果 /結(jié)論]研究表明,科學圖譜揭示的科學結(jié)構(gòu)與作者先前的研究成果和業(yè)界已有科學圖譜的分布較為一致,能有效揭示ESI研究前沿數(shù)據(jù)隱含的科學結(jié)構(gòu)特征,反映科學前沿分布情況。以世界納米前沿全貌圖為基圖,疊加中美在各研究前沿的論文份額,對比分析了中國和美國在世界納米前沿上優(yōu)勢及發(fā)展重心的差異,結(jié)合專家研判給出對策建議,助力納米領(lǐng)域的發(fā)展趨勢研究,取得了實際應用價值。
[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.
