Abstract: Based on analysising the inclusion relation between condition and conclusion of the rules,a new messure of relative significance of attributes is defined,and an approach about the briefest rule acquisition is presented with adding gradually condition attributes.The correctness and effectiveness of the new algorithm are shown in an example.

Key words: rough set, attribute reduction, rule acquisition, significance of attributes
