| 摘 要： | 目的/意义] 提出三重耦合概念，以期通过改变传统耦合的作者频次计算方法，改进因偶然因素产生的过耦合现象，提高领域知识谱图绘制的准确度。方法/过程] 将原始矩阵构建从二重耦合计数改进为三重耦合计数，转化为相关矩阵后，对三维矩阵进行降维处理，通过Gephi软件绘制科学知识图谱并进行数据揭示与分析。结果/结论] 实证研究结果显示，三重耦合一方面保留了二重耦合的领域分析能力，另一方面提高了聚类结果的准确性，更为有效地进行作者可视化分析，有利于领域图谱绘制和子领域发现，挖掘出科学共同体的更多细节。

| Abstract: | Purpose/significance] This paper proposesthe concept of author bibliographic tripling analysis in order to decrease the negative effects of over-bibliographic-coupling by modifying the definition of author bibliographic coupling method. The main purpose of author bibliographic tripling analysis is to improve the accuracy of knowledge domain mappings. Method/process] This paper modifies the coupling frequency calculation into tripling frequency calculation and decreases the number of dimensions of the three-dimension matrix. Gephi is employed to analyze the data and visualize the network. Result/conclusion] According to the results of the empirical studies, our proposed author bibliographic tripling method enhances the performance of knowledge domain mappings, which facilitates to find more sub-fields in visializations. |
