The goal of Information Filtering Systems(IF Systems) is to support users in finding relevant information from a dynamic base of data objectsIF Systems base their relevance computation on socalled user profiles in which they maintain representation of the user's interests.Whenever user's interest change,user profiles become inaccurate and the prediction quality decreases.The more dynamic user's interest is,the more important it is for IF Systems to update user profiles rapidly to shorten this period of decreased prediction quality.A research on method of user profile of existing systems,we analyze them with advantages and limitations.
