A user-interface method of selecting and presenting a collection of
content items based on user navigation and selection actions associated
with the content is provided. The method includes associating a relevance
weight on a per user basis with content items to indicate a relative
measure of likelihood that the user desires the content item. The method
includes receiving a user's navigation and selections actions for
identifying desired content items, and in response, adjusting the
associated relevance weight of the selected content item and group of
content items containing the selected item. The method includes, in
response to subsequent user input, selecting and presenting a subset of
content items and content groups to the user ordered by the adjusted
associated relevance weights assigned to the content items and content
groups.
