Research on User Profile based on Interest Dynamic Change Modeling

Abstract

The profile study based on the modeling of the dynamic change of user interest is a research method that realizes the dynamic update of interest tags by constructing the time decay function of interest transfer, and then constructs the dynamic model to achieve more accurate personalized recommendation and other functions. This article mainly introduces the construction of user interest model based on forgetting mechanism,by comparing various interest models, it can be found that the dynamic change model of interest based on the forgetting mechanism is more capable of constructing a user profile system with accurate delivery effects.
