System, method, and article of manufacture for generating implicit ratings based on receiver operating curves

摘要

An electronic rating broker is provided. The rating broker includes an input mechanism for obtaining an implicit measure concerning items presented to a user. A processor is operatively coupled to the input mechanism and an output device to cooperatively perform several functions. These functions include generating an implicit rating as a function of the implicit measure using a receiver operating curve (ROC). The output device is provided the implicit rating by the processor. In addition, a method is provided for operating an electronic rating broker on a computer system in order to provide an implicit rating generated with an ROC. Also, a storage device readable by a computer system for implementing this method is provided.
