SYSTEM AND METHOD OF USING MOVIE TASTE FOR COMPATIBILITY MATCHING
First Claim
1. A method of predicting the compatibility of at least one item of interest to a user of a web-based system, comprising the steps of:
- (a) providing a survey of items for rating by the system user;
(b) collecting a set of ratings for the survey of items from the system user;
(c) collecting a set of ratings for the survey of items from each of a plurality of raters;
(d) calculating a correlation coefficient between the system user and each of the plurality of raters to obtain a set of correlation coefficients for the survey of items;
(e) selecting a group of raters from the plurality of raters, the group of raters selected on the basis that each member of the group of raters has provided a rating of the at least one item of interest; and
(f) predicting the compatibility of the at least one item of interest to the system user from the ratings provided by the group of raters and the correlation coefficients calculated between the system user and each of the group of raters.

Abstract
A method of predicting the compatibility of at least one item of interest to a user of a web-based system. The method includes the steps of providing a survey of items for rating by the system user, collecting a set of ratings for the survey of items from the system user, collecting a set of ratings for the survey of items from each of a plurality of raters, calculating a correlation coefficient between the system user and each of the plurality of raters to obtain a set of correlation coefficients for the survey of items, selecting a group of raters from the plurality of raters, the group of raters selected on the basis that each member of the group of raters has provided a rating of the at least one item of interest and predicting the compatibility of the at least one item of interest to the system user from the ratings provided by the group of raters and the correlation coefficients calculated between the system user and each of the group of raters.

16. In a web-based system, a method of predicting the compatibility of a first user of the system to at least one other user of the system, comprising the steps of:
-
(a) providing a survey of items for rating by the first system user; (b) collecting a set of ratings for the survey of items from the first system user; (c) collecting a set of ratings for the survey of items from each of a plurality of raters; (d) calculating a correlation coefficient between the first system user and each of the plurality of raters to obtain a set of correlation coefficients for the survey of items; (e) predicting the compatibility of the first system user to at least one of the plurality of raters from the correlation coefficients calculated between the system user and each of the group of raters; and (f) providing to the first system user at least one other user selected on the basis of correlation to the first system user from the plurality of raters. - View Dependent Claims (17, 18, 19, 20)

21. A multi-user web-based computer system for predicting the compatibility of at least one item of interest to a user of the system, comprising:
-
(a) a web server for communicating with users of the web-based computer system and components thereof; (b) a user profile database for storing information on system users; (c) a user rating module for providing a survey of items for rating by the system user and collecting a set of ratings for storage within said user profile database; (d) a computational process module, said computational process module having a correlation module for calculating a correlation coefficient between the system user and each of a plurality of raters to obtain a set of correlation coefficients for the survey of items and a predictive module for predicting the compatibility of the at least one item of interest to the system user from the ratings provided by the plurality of raters and the correlation coefficients calculated between the system user and each of the plurality of raters; (e) a compatibility-based matched items table for receiving an output regarding the compatibility of the at least one item of interest to the system user from the computational process module; and (f) a recommendation process module for receiving information from said compatibility-based matched items table and returning the information to said web server for transmitting to the system user. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
