国内外专利挖掘研究的可视化分析

Visualization Analysis of Patent Mining at Home and Abroad

专利挖掘是专利分析研究中的重要课题,为反映国内外专利挖掘现状与趋势,文章基于CNKI中国学术期刊全文数据库(1981年～2017年)的数据以及WOS数据库(1999年～2017年)的数据,借助可视化工具Citespace、SATI和Ucinet,对国内外专利挖掘领域文献进行可视化分析,选择的可视化项目主要有:作者合作、机构合作、关键词共现。可视化分析结果显示,国内外专利挖掘领域作者合作团体小且少、机构合作较少且多为机构内合作、研究机构多为大学、关键词聚类团较多,还需要进一步增强合作、拓广领域范围、注重应用,才能取得领域突破。参考文献19。

The patent mining is an important subject in the research of patent analysis.In order to reflect the current situation and trend of patent mining both at home and abroad,based on the data of CNKI Chinese Academic Journal(1981-2017)and the data of WOS database(1999-2017),visualization tools Citespace,SATI and Ucinet and selecting the following visualization projects:the author cooperation,institutional cooperation and keyword co-occurrence,this paper gives a visual analysis on the domestic and international patent mining literature.The results show that the cooperation groups in the field of patent mining at home and abroad are small and less cooperative,and the organizations have less cooperation and the cooperation is mostly within the organizations.The research institutions are mostly universities,the keyword clusters are more and need to further enhance the cooperation,broaden the field scope and pay attention to the application to obtain a breakthrough in the field.
