Attribute reduction in generalized one-sided formal contexts

In this paper, we present a new pair of adjoint mappings between a power set and the direct product of complete lattices. The proposed pair of adjoint mappings form a Galois connection and the corresponding concept lattice is constructed from a generalized one-sided formal context. We also propose a...
