With the advent of the era of digital intelligence, the reading environment of university art exhibition halls has undergone profound changes. The characteristics of digital reading form, diversified reading content, data-driven reading recommendation and cross-border integrated reading experience bring users a more convenient, personalized and diverse reading experience. This paper proposes an intelligent digital art exhibition and knowledge dissemination system based on digital technology, and uses digital twin technology to show the intelligent interaction between virtual and reality. Moreover, this paper uses cloud computing, edge computing and distributed storage technologies to store and analyze each user’s behavior information, so as to sort out the user’s personalized information set and feed it back to the art exhibition hall. The experimental results show that the implementation of this mode not only improves the personalization degree of knowledge recommendation, but also promotes knowledge sharing and innovation, and achieves the optimization of knowledge service mode.
