| Abstract: | 【Purpose/significance】The personalized recommendation method based on context-aware has attracted wide at?tention and become a new research hotspot.Method/process]This paper proposes a recommendation model of knowledge resources based on context-aware and presents a collaborative filtering recommendation algorithm based on an improved Restricted Boltzmann Machine with contexts to get the recommended resource in the user's mobile situation.Result/conclusion] The experiments are conducted by real data set,and the result shows that the proposed recommendation method has higher accuracy and better recommendation effect.The proposed model and algorithm based on con text-aware can effectively solve the personalized recommendation problem for users of university in a mobile environment. |
