Abstract :
Based on concept lattice theory and rough set theory, this paper mainly studies the relationship between the property-oriented concept lattice and the partition under the same formal context. Firstly, the approach to change the property-oriented concept lattice into partition is studied. Secondly, the approach to construct the extensions of the property-oriented concept by partition is proposed, thus, the corresponding concept lattice can be obtained naturally. Finally, two algorithms are given.
