Problems and Changes in Digital Libraries in the Age of Big Data From the Perspective of User Services

Based on the investigation of the position of user service for constructing digital libraries in the big data era, this paper points out that not only data resources of modem digital library have the characteristics of big data, but also the existing library services need to use big data methods to achieve reform and innovation, including resource transferring, resource utilization, social identity, thinking innovation. We focus on the importance of user services and types of big data resources that digital libraries can utilize, which include big data within libraries such as user behavior data and digital literature resource, and other big data outside libraries such as scholarly big data. We also examine the problems and potential of digital libraries in the age of big data relative to data, technology, services, and users. Using existing big data resources and considering the characteristics of current users' needs from the perspective of users, more effective ideas and methods to improve existing services in digital library can be put forward. At the same time, it is the personalized need of users in the age of big data that constitute the driving factor for the development of digital library from resource-sharing service to user oriented service.
