技术坐标视角下的主题分析——以第三代移动通信技术为例

Technology Focus Analysis in the Perspective of Technical Coordinate： A Case for the Third Generation Mobile Communication

以第三代移动通信技术领域为例，本文从17864项专利文献的标题和摘要中抽取了技术术语，之后对其进行了技术坐标视角下的共词分析。在卡龙的技术子簇的构建方法基础上，运用饱和值标准进行聚类和技术主题的划分，从技术术语的频次和年份的角度，本文构建了关注度和新颖度指标，并在实证分析中将共词分析法、聚类分析法与技术坐标分析法相结合，绘制出了技术坐标图，展示了第三代移动通信技术领域的技术研发现状和发展趋势。探寻的结果表明，位于技术坐标1、2象限的技术主题超过一半，表明在技术主题中多数是近些年来的研发主题；位于1、4象限备受关注的中心主题和基础主题较少，位于2、3象限属于次级或边缘的技术主题居多。

Taking the patents of third generation mobile communication （3G） in Derwent Innovation Index as data source, the paper extracted the technical terms from the title and abstract to make co-word analysis in the perspective of technical Coordinate. Based on Callon＇s technical cluster method, the paper clustered the different technology focus with saturation limit, then focus indicator and novelty indicator were constructed to reveal the important technology focus. Through the combination of co-word analysis. , cluster analysis and technical Coordinate, the research situation in 3G was displayed in the diagram, furthermore, the paper found that the technology focuses in the first and second quartile, the recent research object, were more than a half, the core research in the first quartile and the basic research in the f^urth quartile less, and the secondary research in the second quartile and the periphery research a little more.
