基于CiteSpace对diffusion model的研究趋势分析

Research Trend Analysis of Diffusion Model Based on CiteSpace

文章利用citespace以扩散模型(diffusion model)为标题,日期为2012—2022年的文献进行数据分析,分别对扩散模型文献的发文量、国家、机构、关键词、文献的引用等这几个方面进行了客观的分析,得到扩散模型的发文量一直呈上升的趋势,说明对扩散模型的研究一直是近几年学者研究的热点。通过对国家和机构的分布,以及发文量的分析,发现中国和美国对扩散模型的研究较多,且各个国家之间线条连接较紧密,说明国家之间对扩散模型的学术交流较广泛,机构之间的合作也较密切,其中中国科学院(Chinese Acad Sci)发文量最多,美国的主要是一些大学机构发表较多。通过对关键词的共现、聚类、突显词、引用文献的分析,可以知道2012—2022年扩散模型在医学类研究领域是一个热点主题,结合其它聚类的标签词,可以知道,扩散模型在生态领域的研究也较广泛,在传染病,机器学习类也受到学者广泛的青睐。

In this paper,Citespace uses the diffusion model as the title and the documents dated from 2012 to 2022 to conduct data analysis.It objectively analyzes the number of documents,countries,institutions,keywords,references and other aspects of the diffusion model documents,and obtains that the number of documents issued by the diffusion model has been on the rise,indicating that the research on the diffusion model has been a hot topic for scholars in recent years.Through the analysis of the distribution of countries and institutions,as well as the number of papers issued,it is found that China and the United States have more research on the diffusion model,and the lines between countries are closely connected,which indicates that the academic exchanges between countries on the diffusion model are more extensive,and the cooperation between institutions is also closer.Among them,the Chinese Academy of Sciences has the largest number of papers issued,while some universities and institutions in the United States have published more.Through the analysis of keyword co-occurrence,clustering,highlighted words and references,it can be seen that the diffusion model in 2012-2022 is a hot topic in the field of medical research.In combination with other clustering tagwords,it can be seen that the diffusion model is also widely studied in the ecological field,and in infectious diseases,machine learning is also widely favored by scholars.
