This paper examines an addition strategy for constructing an attribute reduct based on three-way classification of attributes. Properties of three-way classification of attributes are used to design an algorithm for constructing a reduct by using useful attributes. The algorithm makes sure that every attribute to be added, together with already added attributes, will form a partial reduct (i.e., a subset of a reduct). Based on the results of this paper, it is possible to study a wide class of addition based reduct construction algorithms. Finally, variations of the proposed algorithm are discussed.
