摘要
解析新兴技术主题的概念,同时结合专利文献的特点,利用专利文献提出识别新兴技术主题的初步技术框架,并以工业生物技术领域的专利文献为数据来源,采用文本聚类技术、共词战略坐标分析、共词网络分析、专利分析等方法对该技术领域的新兴技术主题进行实证分析。
This paper investigates the concept of emerging technology topics. With the characteristics of patent documents, the paper proposes the technology framework of detecting emerging technology topics. Taking industrial biology patent documents as data source, integrating the methods of text cluster, strategic diagram analysis, word co-occurrence network analysis etc, it completes the tasks of emerging technology topics identification.
