基于共词分析的技术跟踪可视化研究—以公路工程领域为例

Visualization of Technology Tracking Based on Co-Word Analysis： An Empirical Study of Highway Engineering

通过技术跟踪，可以了解某一技术领域的现状和发展态势，为技术战略的制定提供决策信息支持，但目前对技术跟踪的研究还不够深入。基于此，文章从共词分析的角度，以计算机技术为手段，从数据采集、数据分析和数据可视化三个方面，提出技术跟踪的可视化方法，详细地阐述了此种方法的结构和具体实现步骤。在此基础上。以公路工程领域为例，从个人、机构和国家三个层面进行可视化实验，并着重对中国在此领域的技术情况进行了详细的分析，以此判别技术领域的深层次结构，为技术发展战略的制定做一些基于工程技术分析手段的支撑性工作。

Technology tracking is a useful method in identifying the current situation and trend of development in related technical areas, and can help us provide the information decision-making support for establishment of technical strategy, but the indepth research of technology tracking is not enough. Based on the co-word analysis, the article makes preliminary discussion on the method of technology tracking visualization from three perspective of the data collection, data analysis and data visualization. Meanwhile author try to study visualization experiments of highway engineering from individuals, institutions, national and focus of China is this field of detailed analysis in order to discriminate this field of deep-seated structural, which as a kind of technical analysis is fundamental to of technology strategy selection.
