To create a rating of a tangible or non-tangible object, raters grade the object against another object with respect to an attribute. Multiple such grades are collected in a computing system. These grades are combined to create a single numeric score, which serves as the rating, for the object or object-attribute pair. This method of rating an object is superior to obtaining absolute numeric scores about a particular object or object-attribute pair because this method accurately reflects how an object ranks with respect to other objects.
