Abstract: 【Purpose/significance】University library is a hot field of data intelligence application, constructing a collaborative and effi⁃ cient smart service system by means of data intelligence technology helps to speed up the process of smart construction of university li⁃ brary.【Method/process】This paper summarizes the application status of data intelligence technology in the smart service of university library, through the method of literature investigation and Internet Survey. Expands and deepens the application scenarios of data intel⁃ ligence technology in smart service of university library and constructs the basic mode of smart service synergy system under the guid⁃ ance of synergetic theory.【Result/conclusion】This system provides guidance for the integration and cooperation of data intelligent ap⁃ plication and service scenario, and makes the smart service of university library adapt to the development needs of the data intelli⁃ gence era.【Innovation/limitation】This paper fuses data intelligence technology with smart service scenario of university library, and introduces the theory of synergy. In the future, we will deeply study the specific application scenarios of data intelligence technology in the construction of smart library.
