Research of classification intersection hierarchical granularity algorithm based on concept lattice

Both of the lattice structure of the concept lattice and hierarchical models of the quotient space can be used to layering, and can be obtained figures under certain conditions. Because of the close links between the above, this paper uses the basic method of the lattice structure, upgrades the direct intersection concept at first, then makes up the additional points for this layer, and searches the equivalence classes with the quotient attribute functions, ensures the integrity of the domain in each layer. On this basis, a new algorithm is proposed which integrates hierarchical models and lattice structures to achieve the layering of classification intersecting situation. Example shows the method feasible.
