“…), graph (values are linked together by edges in a graph, i.e., ), set (multiple values can be selected at the same time, i.e., [diagnosis={diabetes, hypertension, obesity}]), set-defined (similar to set, but with additional structure added on top of values, i.e., diagnoses in previous example form a hierarchy), interval (numeric values with defined addition and subtraction, zero is not defined), ratio (numeric values with defined multiplication and division), cyclic-ratio (numeric values forming a cycle, i.e., [angle=276..15]), and absolute (numeric values with only order defines and no operations permitted, i.e., social security number). These attribute types along with additional examples are explained in [38]. Attribute types are critical when attempting to generalize and reason with rules, as well as apply constructive induction methods, i.e.…”
