我国医学专业机器学习相关学位论文文献计量学分析

Bibliometric analysis of Chinese academic dissertations in medical machine learning

目的探寻和解析我国机器学习相关学位论文的基本情况及其研究热点。方法基于中国知网、万方数据知识服务平台,检索时间自建库起至2023年2月14日,检索关键词包含“医学”和“机器学习”的所有全文发表的中文学位论文。采用Microsoft Excel 2016软件进行数据整理,提取的数据包括学位论文收录年份、学位授予单位、导师、被引频次信息。运用VOS viewer软件对高频关键词进行可视化分析。结果共检索出299所高校机器学习相关学位论文2662篇,论文数量排名前10位的学校论文数量之和占全部论文的29.9%(797/2662)。学位论文指导教师共2533名,论文被引频次分布为0至204次。在所有已经发表的学位论文中有46.2%(1229/2662)的论文未曾被引用。学位论文的研究主题主要包括医学影像的辅助诊断、电子病历文本提取、医学图像分割算法优化、多模型高效准确利用等。结论医学专业机器学习相关学位论文及其所属单位和导师数量均较多,但论文质量有待提高,论文热点相对集中于医学辅助诊断方面。

Objective To find and analyze the research trends and future research directions of academic dissertations of medical machine learning in China.Methods All academic dissertations on medical machine learning published in full text in Chinese were obtained by searching the CNKI and Wanfang database.The retrieval period was from the establishment of the database to February 14,2023.The search keywords included″medicine″and″machine learning″.Microsoft Excel 2016 software was used to organize data from retrieved records,including the year of thesis inclusion,institution of degree,supervisor and cited frequency.VOS viewer software was used to visualize and analyze the high-frequency keywords.Results A total of 2662 academic dissertations in the field of machine learning were retrieved from 299 universities.The combined number of dissertations from the top 10 universities accounted for 29.9%(797/2662)of all the dissertations.There were 2533 academic dissertation supervisors,and the citation frequency of the dissertations ranged from 0 to 204 times.However,46.2%(1229/2662)of the published dissertations had never been cited.The research topics of the dissertations mainly included assisted diagnosis in medical imaging,extraction of electronic medical record texts,optimization of medical image segmentation algorithms,and efficient and accurate utilization of multimodal models.Conclusions There is a relatively large number of machine learning-related dissertations in the field of medicine,as well as a significant number of institutions and supervisors.However,the quality of the dissertations needs improvement,and the research hotspots are relatively concentrated in the area of medical assisted diagnosis.
