Recently, fuzzy FCA becomes popular in researchers for representing the knowledge precisely. In this study we present a method for decomposition of given fuzzy formal context into several crisp formal contexts with help of distinct granules of fuzzy relation. The presented method reduces the lattice of given fuzzy formal context into several lattices for refining the interested patterns. From the obtained crisp formal contexts, we can generate the formal concepts in order to visualize them in lattice structure for describing the knowledge of given research field. Proposed method can be helpful for the researchers for reducing number of concepts, visualization of concepts for distinct fuzzy relations, and reduction of fuzzy lattice into several lattices in fuzzy context related fields. © 2012 Published by Elsevier Ltd.
