%X The inequality between algebra view and information view of rough set theory leads to the different result from the inconsistent decision table. Firstly, the differences between the two kinds of the views are studied. Moreover, a new entropy calculation method for decision table is proposed in this paper. Based on this method, a new information view that could comprehensively illustrate the algebra view is introduced, and more efficient algorithms of knowledge reduction will be developed on the base of the new information view which is proved equals to the algebra view.
