基于LDA-SNA和多维空间专利地图的核心技术主题及创新机会识别研究

为把握核心技术、精准高效研判技术机会，提出一种基于LDA-SNA和多维空间专利地图的核心技术主题及创新机会识别方法。首先，采用LDA-SNA方法提取技术主题及要素并筛选核心技术主题；其次，依托多维空间专利地图对核心技术主题要素进行归维处理，并选取创新法则依据维法耦合原理生成基于核心技术主题的技术创新机会；最后，以钛白粉浆料制备技术为例，检索并搜集到1 962条专利为数据集。研究结果识别出6个核心技术主题的7个创新机会，验证该方法的可行性，为相关企业进行技术机会识别以高效开展技术创新提供决策参考依据。

Research on identification of core technology topics and innovation opportunities based on LDA-SNA and multi-dimensional space patent map

In order to grasp the core technology in its field, accurately and efficiently study and judge technological opportunities, a core technology topic and innovation opportunity identification method based on LDA-SNA and multi-dimensional space patent map is proposed. First, LDA-SNA method was used to extract technical topic elements and screen core technical topics; Secondly, the core technology topic elements are dimensioned, and the innovation rules are selected to generate the technology innovation opportunities based on the core technology topics according to principle of dimension-method coupling. Finally, taking titanium dioxide slurry preparation technology as an example, 1962 patents were retrieved and collected as a data set. The research results identify six core technology topics and seven innovation opportunities, verify the feasibility of this method, and provide a reference basis for decision-making for related enterprises to identify technology opportunities to carry out technological innovation efficiently.
