(1) Innovating the concept of library information service The era of artificial intelligence has had a certain impact on the information service of university libraries. Library information service conforms to the needs of the times, attaches importance to the application of advanced technology, promotes the innovation of library information service and improves the level of library information service. First of all, in the process of development, libraries should strengthen the analysis of audience groups, locate readers' reading preferences and preferences, build an all-round intelligent system of library information service by using artificial intelligence technology, exchange, analyze, produce, share and accept information data in the network platform through the application of internet technology, and develop a library information service model through processing these information data to provide guidance for readers' reading service. For example, according to teachers' professional teaching mode and students' professional learning needs, artificial intelligence technology is used to accurately meet teachers' reading needs and provide teachers with professional resource information; For students, we should develop an autonomous learning platform to enhance the wisdom of reading promotion, so as to improve students' learning ability. Secondly, in the library's book information service, we should establish a "reader-centered" working thinking, explore and analyze readers' reading preferences with the technical mode of artificial intelligence perception, mining and dissemination, and provide them with all-round information services.
