Abstract :
In this paper, a double universe formal context is constructed based on an information system, and a double universe concept lattice is introduced. Properties of them are discussed. Then a dependence space based on the double universe concept lattice is shown. According to the congruence on the dependence space, a closed set can be obtained, and a new approach to construct the double universe concept lattice is proposed
