Abstract

The invention discloses a method for personalized recommendation based on an OCEAN model. By establishing the OCEAN model of microblog users, the method for personalized recommendation based on the user OCEAN model is realized. When building the user's OCEAN model, the user's microblog text is imported into the LDA model, and the implicit meaning is found from the text in an unguided way to improve the accuracy of prediction. At the same time, the personalized recommendation is based on user clustering, which narrows the user's search range and reduces the calculation amount of real-time recommendation. Combining the user's OCEAN model with personalized recommendation, and in-depth research on the user's personality characteristics, the personalized recommendation process is more in line with the user's psychology and has higher accuracy.
