This paper introduces the concepts of augmented formal contexts and generalized approximable concepts, and proves that in an augmented formal context, the generalized approximable concepts generate a continuous lattice, and vice versa. Furthermore, the notion of C-mappings is proposed to describe the relationships between augmented formal contexts, and it is shown that this category is equivalent to the category of continuous lattices with morphisms being Scott continuous functions.
We introduce the notions of augmented formal contexts and generalized approximable concepts and show that all the generalized approximable concepts of an augmented formal context generates a continuous lattice under inclusion order, on the contrary, each continuous lattice can be obtained by this way. Furthermore, the notion of C-mappings is proposed between augmented formal contexts to obtain a category of augmented formal contexts. Then we show the category is equivalent to that of continuous lattices whose morphisms are Scott continuous functions.
