Method and system for selecting an information item

摘要

A system for enabling a user to select an information item from a set of information items displays a classification scheme comprising categories and sub-categories. After selection of a category by the user, the system modifies the displayed classification scheme by displaying non-selected categories and sub-categories in a way that is dependent on the selected category. The modified scheme then comprises sub-categories that are relevant to the non-selected category, thereby helping the user to find information of interest, without overwhelming the user with too many sub-categories.
