摘要
本文将专利共类关系界定为生产知识(主分类号)和接收知识(副分类号)。在此基础上,引入IPC技术索引表将共类矩阵转换为技术知识流网络。基于德温特创新索引(DII)收录的4G技术专利,利用块模型方法挖掘4G技术知识流网络,发现了兼具内聚性和外联性的关键技术子群。
Co- classification was decomposed into knowledge producer (main IPC) and knowledge receiver (attxiliary IPC) in tiffs study. Then, coclassification matrix was transformed into technological knowledge (TKF) network according to IPC- Technology Concordance Table. 4G patents were collected from Derwent Innovation Index (DII) to construct a technological knowledge flow network. Key technology cluster with high cohesion and external connection was revealed from 4G TKF network by blockmodels analysis.
