引文耦合分析可视化系统设计与实现

Research and Implementation of Bibliographic Coupling Analysis Visualization System

根据引文耦合分析流程,基于开源可视化工具开发引文耦合分析可视化系统,包括数据存储、引文耦合计算、可视化等三个模块,能够实现三种相似度规范化系数、用户自主设置阈值、抽取子结构、输出基础文献等功能,还提供多种交互设置,方便用户在多种条件下进行可视化分析。最后,以竞争情报为例,利用该系统可视化分析该领域1998-2008年的研究热点,并输出相应的基础文献。

Based on the process of bibliographic coupling analysis,the authors develop bibliographic coupling analysis visualization system with the open source visualization tool. This system consists of three modules ： data storing module, computing modules of bibliographic coupling, visualizing module. It has implemented many functions, such as three similarity measures for normalizing bibliographic coupling strength, user self-set threshold, extracting sub structure, outputting intellectual base. Also, it is very convenience for users to explore visualization analysis by providing many functions of human computer interaction. Finally, the authors take competitive intelligence as an example, explore the visualization analysis of competitive intelligence in China between 1998 to 2008 by this system, and output the corresponding intellectual base.
