| Abstract: | The concept of the information quantity of decision attribute with relation to given condition attributes is proposed and method how to deal with deduction of attribute in consistent decision tables is given accordingly. In addition,it is proved that this method is consistent with the classical algebraic method. It is shown that this method is feasible and effective through running an example. |
