A system for determining selections that a user is likely to be interested in.
The determination is made based on the user's prior indicated preferences. The
user designates his or her preferred selections as entries in a user's preference
list. Entries in the user's list are compared with entries in the other users'
lists. When a significant number of matches have been found between two lists,
the unmatched entries of the other user's preference list are extracted. The unmatched
entries are further processed. Those unmatched entries with a high correlation
to the user's preference list are presented to the user as selections in which
the user is likely to be interested.
