The application of LDA model on user profile

This paper puts forward the method of user profile technology based on LDA model. Abstracting the behavior and transaction information of the research object into the document, the LDA model can be trained and the research object can be described into the property tags, thereby to realize the user profile. The experimental results show that describing the research object as multidimensional labels based on LDA model can effectively characterize the research object and form their user profile.
