Abstract: This paper proposed an approach to construct an incomplete context with two complete contexts.Axiomatic characterizations of approximate concept lattices in complete contexts were obtained based on those of Wille’s concept lattices in formal contexts.Then a new method of building approximate concept lattice was presented,enriching the existing theory related to the approximate concept lattice.
