技术领域主题发现研究——以基因工程疫苗领域为例

摘要

The paper systematically summarizes the development process of research methods on technological domain recognition based on patent documents,proposes a research flow to efficiently obtain patent technical keywords and generate the strategic diagram,and makes an experimental analysis on the technological domain distribution and development trend taking gene engineered vaccine technology for example.The research result proofs that,under the co-word analysis flow proposed by the paper,patent co-words clustering and strategic diagram can be used effectively to recognize technological domains and their development currents.%本文梳理基于专利文献进行技术领域主题发现的研究方法发展进程,提出一套高效获取专利技术主题词、生成战略坐标图的研究流程,并以基因工程疫苗技术为例,对我国基因工程疫苗技术主题分布及发展趋势进行实证分析.研究结果显示,采用本文构建的共词分析流程和方法,利用专利共词聚类和战略坐标图能较好地识别技术主题及其发展现状.
