摘要
基于工业机器人专利数据中的德温特手工代码,从频次强度与概念强度两方面构建高频词关联矩阵,结合社会网络分析方法,分析其各个时期阶段的技术主题结构演化。结果发现:工业机器人领域技术主题可以划分为3个阶段时期,其结构显现出分散到集聚再到分散的变化;3个阶段时期的技术主题产生了变化但仍存在较大相似性,其中有6个完整德温特手工代码所表征的技术主题是3个阶段时期的共性技术主题,应时刻引起关注。
Based on Derwent manual code of industrial robot patent data,the high-frequency word correlation matrix is constructed from frequency intensity and concept strength.Combined with social network analysis method,the evolution of technology topic structure in each period is analyzed.It is found that the technical subject of the industrial robot field can be divided into three time periods,and its structure shows changes from dispersion to agglomeration to dispersion;the technical topics of the three time periods have changed but there are still large similarities,of which there are six virtues.Winter’s manual code is a common technical theme for three time periods.
