| 摘 要： | 目的研究多粒度面向对象概念格的构造。方法在单粒度面向对象概念格外延集上作并运算,得到多粒度面向对象概念的外延集,再运用下近似粒算子,得到多粒度面向对象概念的内涵集,进而构造多粒度面向对象概念格。结果给出了由单粒度面向对象概念格构造多粒度面向对象概念格的方法。结论多粒度面向对象概念格的提出进一步完善了概念格理论。

| Abstract: | Aim To reserch the structure of multi-granulation object oriented concept lattices.Methods Based on the extents of a single granulation object oriented concept lattice,the exents of multi-granulation object oriented concept lattice are obtained,with the lower approximation granular operator,the intents of multi-granulation object orenented concept lattices are obtained.Finally,the multi-granulation object oriented concept lattice can be constructed.Results The multi-granulation object oriented concept lattice can be constructed by some single granulation lattices.Conclusion The introduction of multi-granulation object oriented concept lattice is to improve the object-oriented concept lattice. |
