In view of the needs of ADS-Advertisers which are used in social network sites,user interests are divided into two categories which are long-term interest and short-term interest.By using the user registers information to get long-term interest and short-term interest could be gathered by catching users′browser behavior,the stable interest model and the immediate interest model could be built separately.Using both models together,a real time user interest model will be created which could form complete interest of users in real-time.Meanwhile,the update method is based on natural forgetting that means to combine human forgetting with the model update method.In the end,the validity and accuracy of this model will be verified by the experiment.
