摘要
基于专利中术语共现关系,采用同质块建模方法对连续时间段术语共现网络的变化情况进行聚类,以识别技术演化过程中的新兴技术系统构成,并且以硬盘驱动器领域磁头技术为例进行实证分析。实证结果表明,该方法能够对技术系统构成进行有效识别。
Based on terminologies＇ cooccurrence among patent documents, this paper clusters difference between terminologies＇ cooccurrence network of sequential phrases via homogeneity block modeling on purpose of getting upand coming technological architecture component during technological evolution process. After that we employ head techniques of hard disk drive to execute our empirical analysis, the result shows that our method can recognize technological architecture component effectively.
