Abstract: Named entity recognition has made great achievements in China after decades of development. In this paper, CiteSpace is used as an analysis tool to visually analyze the papers on the topic of named entity recognition in CNKI. Through author analysis, research organization analysis, and keyword analysis, this paper discusses the research path and research focus of named entity recognition in China. The results show that a number of influential authors and research institutions have emerged in China. The research path of our country has gone through three stages. At present, the research hotspot in our country is the deep learning method of named entity recognition.
