ABSTRACT:
A method and system for generating notifications of auctions based on user notification requests. In one embodiment, the notification system receives from users selection specifications that specify the types of auctions for which the user is to be notified. The selection specifications may include a category of the auctions, keywords for identifying auctions, and values for attributes associated with the category. When the notification system receives a selection specification, it determines whether that selection specification is the same as or nearly the same as other selection specifications that have been received. The notification system periodically determines whether any new auctions satisfy a selection specification by submitting a query to an auction database and then notifies the users when new auctions are identified. The notification may include a list of auctions that is sorted based on access patterns of users who are presented with lists of auctions using selection specifications with similar category, attribute, or keyword values.
