| 摘 要： | 目的基于基概念构造面向属性概念格。方法通过每个对象对应的面向属性概念格的基概念,利用其外延与内涵逐层寻找面向属性概念。结果利用基概念找到全部面向属性概念,从而得到完整的面向属性概念格。结论利用基概念可以逐层获得所有面向属性概念,也可以解决其他类型概念格的构造问题。

| Abstract: | Aim To construct property-oriented concept lattices based on elementary concepts.Methods Through the elementary concepts to search for all property-oriented concepts layer by layer.Results All the extensions of the property-oriented concept lattice are found and corresponding lattice is constructed.Conclusion The novel construction method can find all the extensions layer by layer,and can be used in construction of other kinds of concept lattices. |
