A Novel Attribute Reduction Algorithm of Concept Lattice

Concept lattice is a form of conceptual classification of the object or concept hierarchy based on the crisp relation between object set and attribute set. It has been used with a high intensity to knowledge reduction. Through the in-depth study of concept lattice, this paper presents the definition and natures of attribute importance in concept lattice, and accordingly illuminates an attribute reduction algorithm of concept lattice. An example shows that the algorithm is feasible and effective.
