| Abstract: | The theory of concept lattice is an important theory of data analysis and knowledge discovery.Since knowledge reduction is an important aspect of knowledge discovery,it is necessary to find a simple and effective approach for knowledge reduction.From the viewpoint of ECII algebraic structure in formal context,this paper studies reduction method of concept lattices,proposes some judgment theorems and attribute characteristics. |
