Abstract

The invention discloses a personalized recommendation method based on an OCEAN model, and a personalized recommendation method based on a user OCEAN model is implemented by establishing an OCEAN modelof a microblog user. When the OCEAN model of a user is established, a microblog text of the user is imported into an LDA model, the implied meaning is discovered from the text in an unguided manner,and the accuracy of the prediction is improved. At the same time, the personalized recommendation is built on the basis of user clustering, the search scope of the user is narrowed and the calculationamount of real-time recommendation is reduced. The OCEAN model of the user is combined with the personalized recommendation, an in-depth study is conducted on personality traits of the user, the personalized recommendation process is more in line with the psychology of the user, and the accuracy is higher.
