Generalized attribute reduction in consistent decision formal context

Formal concept analysis, as an effective tool for knowledge discovery, has been successfully applied to various fields. This paper deals with approaches to generalized attribute reduction in consistent decision formal context. The concept of generalized attribute reduction in consistent decision formal context is first introduced. The judgement theorems and discernibility matrices are established, from which we provide the approaches to generalized attribute reduction in consistent decision formal context based on concept lattice.
