System and method for predicting the ranking of items
First Claim
1. An interactive method of creating a consolidated ranking in response to a request for a prediction from a requestor where the consolidated ranking predicts how the requestor would rank items, which may be unfamiliar to the requester, using reports that have been provided by a plurality of users containing the order that items are ranked, said items selected from one or more of the categories of products, services, performers, competitors, events and the like;
- where the method includes the sequential steps of;
(a) presenting to said users a list containing three or more items, said users may include said requestor;
(b) obtaining from said users, reports ranking three or more of the items presented in step (a);
(c) creating groups of said users by choosing some of the users to be lead users;
calculating correlation between the order that items are ranked in the report of a lead user and the order that the same items are ranked in the report of another user when the reports of both users contain at least three of the same items; and
grouping together all users whose reports have calculated correlation with the lead user in excess of a predefined value;
(d) creating separately for each group formed in step (c), a consolidated ranking of all items included in the reports of at least three users in the group by an iterative process that orders items on the basis of the number of times that users in the group rank an item higher than another item when the number of times such assessment is made is weighted by the sum of weights assigned to the two items where those weights were calculated in the previous iteration and where the items'"'"' weights for the first iteration are predetermined;
(e) calculating correlation between the order in which items are ranked in each user'"'"'s report and the consolidated ranking of every group derived in step (d) and then assigning said user to the group with which the said user is most highly correlated;
(f) repeating step (d) using the new groups formed in step (e);
(g) repeating steps (e) and (f) until there is no change in the membership of any group and no change in the list of items in each group'"'"'s consolidated ranking;
wherein by this process a consolidated ranking for a group, containing predictions based on a request, can be created even though the items in the report of the requester may not overlap with any of the items in the reports of some of the other said users in the same group.

Abstract
An interactive method of responding to a request to predict how a user would rank items which may be unfamiliar to that user. The invention uses reports provided by a plurality of users containing the order in which the users ranked a selection from a list of items. Items are selected from one or more of the categories of products, services, performers, competitors, events and the like. The process involves the creation of a group of users where the group can include some users who have not necessarily ranked any of the same items as the requestor.
