Attribute-oriented fuzzy concept lattices and standard fuzzy concept lattices induce the same similarity on objects ?
G. Ciobanu, C. V?ideanu (2015) [1] define the similarity of objects in attribute-oriented fuzzy concept lattice and claim that it is different from the similarity of objects induced by the corresponding fuzzy context. We show that this claim is wrong and that the two similarities are equal. As a consequence we get that attribute-oriented concept lattices and standard concept lattices induce the same similarity on objects.
