| 摘 要： | 基于专利引文的科学—技术关联探测方法包括三大步骤:以引用关系为纽带,建立代表技术知识的专利方数据集与代表科学知识的论文方数据集之间的对应关系;确定论文方所代表的科学学科和专利方所代表的技术领域;建立科学学科与技术领域间的映射,描述并显示双方的知识溢出关系。但这三大步骤中分别存在以下问题:一是不区分专利对论文的引用类型将导致探测误差;二是依据IPC的分类方法不能反映专利方子技术领域的知识类别;三是现有探测方法中缺失科学论文对技术创新的反向引用计量。

| Abstract: | The method to detect the linkage between science and technology based on patent citation includes 3 major steps:take the citation relationship as the link to establish the corresponding relationships between patent data set representing technological knowledge and thesis data set representing scientific knowledge;determine the scientific discipline represented by the thesis and the technological domain represented by the patent;establish the mapping between scientific discipline and technological domain to ... |
