摘要
目的研究合成背景下面向属性概念格的生成。方法面向属性概念格理论。结果由两个简单形式背景的面向属性概念格获得了合成形式背景的面向属性概念理论。结论推广了已知结果,易于获得复杂形式背景的面向属性概念格,从而更有利于知识发现。
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.
