摘　　要：提出了决策表中决策属性相对于条件属性的条件信息量的概念,由此从信息量角度给出了一致决策表的属性约简方法,并且证明了该方法与属性约简的代数方法是一致的.通过实例表明该方法是可行的和有效的.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.
