There are six steps to construct user portraits for public welfare book users: user data collection, user data processing, user data label extraction, user data interaction association, user data application implementation, and user data feedback. Constructing the user portrait model of public welfare books in China is theoretically and technically feasible. Still, it faces some difficulties in the process of promotion and application: it is difficult to collect data, it is difficult to achieve the accuracy of real-time user portraits, there is a lack of feedback process, and the analysis of user growth process is neglected. It is suggested that effective targeted countermeasures should be adopted to solve the problem: diversification of data collection indicators, detailed classification of user tags, maintenance of the positive image of public welfare book reading service providers, and a friendly visual interface for feedback.
