目的/意义]现代社会已进入大数据时代，基于用户画像的智能信息服务深刻地改变了人们的生活，对图书馆领域产生了重要影响，研究用户画像对社会的发展具有重要作用。方法/过程]以CNKI中国学术文献网络出版总库中的用户画像文献作为研究对象，使用CiteSpace绘制可视化知识图谱，进行关键词分析，揭示我国用户画像研究的时间分布、学科领域、主题演变和研究热点问题。结果/结论]我国用户画像研究划分为初始阶段、起步阶段和发展阶段，从2015年开始快速发展，但基础理论研究较少，研究成果尚未形成体系；用户画像研究文献从最初的计算机和电子商务等学科领域逐渐向管理学、经济学、人文社科领域发展，呈现出明显的跨学科特征；大数据构成了用户画像研究的数据基础，随着计算机和信息网络技术的发展，用户画像研究和实践应用不断发展，图书情报与数字图书馆是用户画像研究的重要领域；研究热点包括基础理论、核心技术、实践应用和基础数据四方面内容。

Research of Knowledge Network and Hotspots of User Portraits in China

Purpose/Significance]The modern society has entered the era of big data.Intelligent information services based on user portraits have profoundly changed people's lives.Studying portraits of users plays an important role in the development of society.Method/Process]Using the user portrait literature in the CNKI Chinese academic literature web publishing library as the research object,CiteSpace was used to draw the visual knowledge map and keyword analysis,revealing the time distribution,subject areas,and theme evolution of the user portrait study in China.Result/Conclusion]The study of user portraits in China has developed rapidly since 2015,but the research results have not yet formed a system;the user portrait study literature has gradually moved from the initial computer and e-commerce fields to management,economics,humanities and social sciences.The development showed an obvious interdisciplinary character;big data constitutes the data foundation for the study of user portraits.With the development of computer and information network technologies,the study of user portraits and the practice and application in various industries were continuously developing.Library Information and Digital Library were important area for user portrait studies;research hotspots included basic theory,core technology,practical application,and basic data.
