摘要：
The main purpose of this paper is to present the methods of recognizing attribute characteristic and determining attribute reduction. Based on the binary relation between objects and attributes in a formal context, the properties of irreducible elements in extent closure systems are discussed. Some equivalence conditions that can recognize attribute characteristics are presented. A new reduction approach in concept lattices is derived by using the classification of attributes determined by the irreducible elements.
