Abstract: This paper points out that the traditional knowledge service model is still on the base of the inherent resources or system, and its service is “point-to-point” extensive static service specific to users independent interests, which is low efficiency; however, the users’ research process is dynamic, there is a significant demand shift state, forming a dynamic continuous process. Thus proposed the concept of Elaborating Knowledge Service, based on users’ academic research process, this paper would dynamic trace the demand shift state of users in different study process, using “face-to-face” knowledge space to greatly improve the effect of knowledge service, and through experimental study validate the formation of user demand shift and knowledge space, as well as the theoretical and practical significance of the issues raised in this paper.

Key words: refined knowledge service, study process, demand shift, knowledge space
