1. A rule generation system comprising: a memory storage device comprising: an evaluative expression framework defining an evaluative expression category; an evaluative expression parameter associated with the evaluative expression category, wherein the evaluative expression parameter defines the evaluative expression category type of an evaluative expression; and executable instructions that define: an evaluative expression parameter module operative to receive an evaluative expression parameter value that represents the evaluative expression category type for the evaluative expression parameter; and an evaluative expression generator module operative to generate an evaluative expression using the received evaluative expression parameter value, wherein the evaluative expression defines a conditional statement that corresponds to the evaluative expression category type; and a processor operative to execute the executable instructions.
