Abstract: Library user information mining is an effective method to promote library management efficiency, and realize high quality user management and user service. The library user information mining technology based on cloud computing in the big data environment is researched to build the structural system of the library user information mining technology. The data layer of the system includes user′s basic information, book borrowing historical data, book information consultation records and so on. The user information data is preprocessed with the modes of noise reduction processing and missing data processing. The cloud computing layer is based on computing resource and storage resource, in which the type of library user groups are divided into two aspects of users borrowing situation and users′interest type by means of the k?means clustering algorithm. According to the divided users borrowing information, the association rules of user information are obtained to form the rule base by means of the colony rule mining algorithm. The personalized recommendation is performed by the application layer on the basis of the mining results of the cloud computing layer. The mining results of user information show that the researched technology can effectively mine the interest types of library users, user group information and time series information.
Keywords: library user; information mining; cloud computing; big data environment; user classification; personalized recommendation
