Abstract: In this paper, we introduce the notion of BF-contexts and show that the set of hyper-concepts of the BF-contexts is a bifinite domain. Conversely, given a bifinite domain we can obtain a BF-context such that all the hyper-concepts of it is isomorphic to the bifinite domain. Further, We obtain category equivalent to that of bifinite domains and BF-contexts.
Keywords: Rough approximable concept, BF-context, Bifinite domain, categorical equivalence
