CA 2704396

A system organizes sets of items for navigation, education, selection, and/or acquisition. Sets of items are organized into hierarchical groups according to item attributes and explicitly and implicitly expressed user and/or content provider preferences. Preferences are represented by a preference model that may include a utility function that specifies which types of items are preferred and in which order according to a specific set of preferences. Optimization techniques may be used to find the optimal parameter values for the preference model. The preference model may be updated over time to reflect increased knowledge gathered about the user's and content provider's preferences. Each group of items may include a representative item and a corresponding group description. Representative items and group descriptions may be selected and displayed using the user preference model. The system may receive explicit input when the user submits a query to the keyword search or filters.
