[Purpose/significance] Constructing the user's cognitive structure, and recognizing the digital library users'real knowledge needs, this paper aims to provide the basis for the personalized knowledge service of digital library. [Method/process] The paper uses the spreading activation theory of cognitive psychology to analyze the cognitive procedure of users,and studies the users' cognitive based on their browsing behavior information in the digital library. [Result/conclusion] This paper's experiments show that whether the index of recPrecision or the index of ranPrecision reach a high level which proves the validity of the digital library user's cognitive structure mining method based on spreading activation theory.
