| 摘 要： | 共词分析是图情领域的基本分析方法之一,探索构建时序共词网络并实现其动态可视化,对于改进、丰富经典共词分析方法具有一定的意义。本文提出时序共词网络构建及其动态可视化方法,首先抽取关键词时间标签,利用关键词的时间标签及其共现关系构建时序共词网络邻接表单数据;然后,基于可视化方法构建时间分层的共词网络图谱,并结合交互式可视化技术实现时序共词网络的动态可视化,从而有效揭示共词网络的动态演变过程。通过对我国图书馆学、情报学领域的数据挖掘相关研究进行实证,验证了本文提出方法的可行性和有效性。

| Abstract: | Co-word analysis is a basic analysis method in the field of information. Exploring the construction of a temporal Co-word network and its dynamic visualization has certain significance for improving and enriching classical Co-word analysis methods. In this paper, a method of constructing a temporal Co-word network and its dynamic visualization is proposed. First, the time label of keywords is extracted and then the adjacent form data of the temporal Co-word network are constructed by using the time label of keywords and their co-occurrence relationships. Then, a time-stratified Co-word network map is constructed, on the basis of the visualization method, and the dynamic visualization of the temporal Co-word network is based on interactive visualization technology, thus effectively revealing the dynamic evolution process of the Co-word network. The feasibility and validity of the method proposed in this paper have been verified through empirical study of data mining in the field of Library and Information Science in China. |
