| Abstract: | Aim To study the construction of property oriented concept lattice through the combination of formal contexts.Methods The theory of property oriented concept lattices.Results The theory can obtain property oriented concept lattice of the combined formal context through property oriented concept lattices of two original formal contexts.Conclusion This results will simplify the construction of concept lattices and facilitate the process of knowledge discovery,especially for large and complex formal contexts. |
