面向技术演化分析的多主路径方法研究

目的/意义]基于当前技术演化分析方法的发展现状,提出一种能够在微观层次上突出既定领域中主要技术发展脉络的多主路径方法。方法/过程]将专利文本挖掘和动态规划方法应用于专利引文网络,以路径上所有专利对的语义相似度总和最优作为启发策略进行路径搜索,以获取若干能够分别聚焦于特定主题的主路径,供研究者总览既定技术领域中主要技术主题的发展脉络及其相互关系。结果/结论]实证结果表明,将该方法应用于硬盘驱动器磁头领域,可以有效抽取其中主要技术主题的演化轨迹。

Research on Multiple Main Paths Method Oriented to Analysis of Technological Evolution

Purpose/significance]Based on current development of technological evolution analysis methods, this paper proposes a new method which can highlight main technology paths simultaneously on certain field.Method/process]Taking global optimum of certain defined function as heuristics, this method applies text mining and dynamic programming on patent citation network to search multiple main paths which focus on certain technology topics, so enable researchers to overview main trajectories for technologies focusing on different topics, then explore relation between these technologies.Result/conclusion]We apply this method on technology of hard disk drive head, and the empirical result shows that it can extract evolution trajectories of main technology in target field effectively.
