| 摘 要： | 〔摘要〕 对CSSCI来源文献标引主题词进行多维聚类分析:首先选择22个学科及其来源关键词数据，通过建立相似性矩阵分析各学科关系，并采用降维办法在二维平面上显示22个学科的相对位置，然后将各关键词按照其和各学科的关系，通过可视化的主题词分布图绘制中国人文社会科学的科学地图，借助该地图可以可视化地了解当前国内人文社会科学各学科关系，揭示2000-2004年中国人文社会科学发展的基本关系和趋势。

| Abstract: | Map of Science is a helpful tool in analyzing the relations and cross-links between different subjects. This paper gives a multi-dimensional clustering analysis on the CSSCI source documents' indexed subject words: firstly, it chooses 22 subjects and their source keywords data and carries out the analysis on the relations between these subjects by building a similarity matrix., and lays out these subjects on a two-dimensional plane. Secondly, it orders all the keywords by the relational level parameter between subjects and drawing the Map of Science of China humanities & social sciences by the visualized distribution chart of these keywords. Finally, it points out that under the help of this map, the relations between the subjects of China humanities & social sciences can be clearly understood and the development trend can be better surveyed. |
