[Purpose/significance] With the rapid development of big data and artificial intelligence, the research of user portraits has quietly emerged. Reviewing and combing the research status has important theoretical and practical significance for promoting the long-term development of user portraits. [Method/process] Based on China Knowledge Network (CNKI) database, Emerald and Web of Science English database, the paper used Citespace, Vosviwer and other visualization tools to analyze quantitatively the current user image research in the library and information field, in terms of research institutions, cited journals, research hotspots and the density of hotspots, etc. The paper also used the mind map to elaborate on the research theme, research algorithms and techniques, model construction and the practice and application of user portraits of user portraits in the field of library and information at home and abroad. [Result/conclusion] As an emerging research tool, the research on user portraits in China is still weak, which has a large space for exploration. The future research of user portraits should focus on:broadening the research theme of user portraits, paying attention to the behavior analysis of user portraits and optimizing the research model of user portraits.
