【摘要】：中国国家自然基金是由国家自然基金委员会管理的基金项目。这个面向全国的资助项目根据国家科学技术发展的方向以及国家发展迫切需求对基础研究与应用进行资助。因此,历年来资金分布的变化揭示了国家科学技术的发展趋势。国家自然基金分布的数据并非是静止不变的。每年国家资助项目都会根据科学技术发展,国家需求,地域学科研究的扶植以及人才培养等问题进行调整。为了捕捉这种动态的数据变化,需要对国家自然基金资助项目的数据进行动态的数据可视化。由此,我们可以相应地更改其他相关的产业。大部分的动态数据可视化都期望揭示整个大型数据集中所有数据的变化情况,而本文所做的是一个略微轻量级的研究,即对国家自然基金数据集中项目,领域的变化情况进行可视化分析以期对国家科技发展趋势的研究有所帮助。在本篇论文中我们使用泰森多边形可视化技术,运用细胞增长消亡自然过程的视觉隐喻来模拟国家自然基金数据的动态变化。这种视觉流程能够使非专业观众可以直接感知国家自然基金分布的变化。使用泰森多边形的动态可视化过程分为两个部分。第一个部分即静止的每个泰森多边形代表不同的领域,颜色代表所受到的投资的程度。第二层为动态增加或者减少的泰森多边形代表了新领域的出现或者旧领域的消亡。三个研究案例将展示它们的不同应用。
[Abstract]:China's National Nature Fund is a fund project managed by the State Nature Fund Committee. This national funded project supports basic research and application according to the direction of national science and technology development and the urgent need of national development. Therefore, the change of capital distribution over the years reveals the development trend of national science and technology. The data on the distribution of the National Nature Fund are not static. Every year, the state-funded projects will be adjusted according to the development of science and technology, the needs of the country, the support of regional discipline research and the cultivation of talents. In order to capture this dynamic data change, it is necessary to visualize the data of projects funded by the National Nature Fund. As a result, we can change other related industries accordingly. Most of the dynamic data visualization is expected to reveal the changes of all the data in the whole large data set, and what this paper does is a slightly lightweight research, that is, the visual analysis of the changes in the data set projects and fields of the National Nature Fund in order to be helpful to the research of the development trend of national science and technology. In this paper, we use Tyson polygons visualization technology to simulate the dynamic changes of National Nature Fund data by using the visual metaphor of the natural process of cell growth and extinction. This visual process enables non-professional audiences to directly perceive changes in the distribution of the National Nature Fund. The dynamic visualization process using Tyson polygons is divided into two parts. The first part, each Tyson polygons at rest, represents a different field, and the color represents the degree of investment received. The second layer is the dynamic increase or decrease of Tyson polygons, which represents the emergence of new fields or the demise of old ones. Three study cases will show their different applications.
