First Claim
1. A prediction information system for use between a user and a collaborative filtering electronic rating broker, comprising:
- (a) user interface means for presenting items as information to the user;
(b) input means for receiving data input by the user;
(c) processing means, operatively coupled to the user interface means and input means, for obtaining a particular implicit measure, generating an implicit rating as a function of the particular implicit measure, submitting the implicit rating to the collaborative filtering rating broker, receiving prediction results for other items from the collaborative filtering, rating broker, and presenting the prediction results to the user on the user interface means.

Abstract
A prediction information system for use between a user and an electronic rating broker is provided. The prediction information system includes a user interface for presenting items as information to the user. An input mechanism receives data input by the user. A processor in cooperation with the user interface and the input mechanism performs an algorithm for: obtaining a particular implicit measure, generating an implicit rating as a function of the particular implicit measure, submitting the implicit rating to the rating broker, receiving prediction results for other items from the rating broker, and presenting the prediction results to the user through the user interface. In addition, a method for operating an electronic rating broker on a computer system in order to provide prediction information to a user based on implicit ratings is provided. Also, a storage device readable by a computer system for implementing this method is provided.
