Abstract

The theory of concept lattices is an efficient tool for knowledge discovery and processing. This paper discusses the relation between objects and attributes using the theory of concept lattices. Based on two formal contexts, which describe correlation relations among objects and possessing relations between objects and attributes respectively, the possessing relations between a new object and the known attributes are studied, and the corresponding possessing degrees are obtained. This method can discover the potential and unknown relations between a new object and the known attributes.
