Recently a model that incorporates user profiles for a priori query improvement has been proposed.* By personalizing the user query, we obtain two immediate and important advantages. It is possible to retrieve broader range of documents, part of which would not be brought to the user's attention if only queries were used. It is also possible to tailor the retrieved information to a particular user's interests and preference. Since a user's interest will probably be changed as time goes, it seems more appropriate that document space should not only change but have different density which reflects the weights of the information in user profile. Dynamic user profile issues and design are considered. Conversion process of a Boolean query into a standardized form for incorporating user profile into the conventional Boolean system is also considered.
