Object oriented concept lattice construction through the combination of formal contexts

This paper studies the construction of object oriented concept lattice through the combination of formal contexts. Based on two original formal contexts with a fixed object set, the construction method for all object oriented concepts and corresponding concept lattice of the combined formal context is obtained. The method can be generalized to the case of many original formal contexts. This method will simplify the construction of concept lattices and facilitate the process of knowledge discovery, especially for large and complex formal contexts.
