摘  要:
[目的 /意义]国家自然科学基金的立项资助是科研能力的重要体现,分析双一流大学的科研基金的立项数据有助于为大学建设提供战略支持。[方法 /过程]研究国家自然科学基金委员会在1998年—2017年资助项目的关键词数据,先对双一流大学进行预处理,然后利用MATLAB中t-SNE算法对结果进行数据降维和可视化。从时间维度和依托单位维度进行建模,研究过去20年内,双一流大学项目的关键词分布。[结果 /结论]方法比传统基于结构化分析的方法更直观,为大学建设战略制定的提供参考。另外,相关学者也可以在笔者研究基础上,进一步建模和编程,尝试例如进行交互式的可视化建模,对海量项目数据进行快速定位,以提高科研效率。

摘  要:
[Purpose/Significance] The National Natural Science Foundation's project funding is an important indicator of scientific research capabilities. Analysis of the data of the establishment of the research funds of double first-class universities is helpful to provide strategic support for university construction. [Purpose/Significance] This article studies the keyword data of the National Natural Science Foundation of China from 1998 to 2017. At first we preprocess double first-class universities' data, and then use the t-SNE algorithm in MATLAB to reduce the dimension of the data and visualize the results. This paper models from the time dimension and the unit-dependent dimension, and studies the keyword distribution of double first-class universities' projects in the past 20 years. [Results/Conclusions] The method in this paper is more intuitive than the traditional method based on structured analysis and provides a reference for the formulation of Chinese universities' construction strategies. In addition, other scholars can further model and program based on this research for such purposes as interactive visual modeling and fast and positioning of massive project data to improve scientific research efficiency.
