    We study relationships between compositions of fuzzy relations (for- mal fuzzy contexts) and morphisms of the structures (concept lat- tices) associated to the fuzzy relations. In particular, we study concept lattices of both, isotone and antitone concept-forming operators which are associated to the fuzzy relations. The presented theory brings new results on characterization, reduction, and similarity issues regarding concept lattices. Moreover, it brings a new insight to Boolean matrix theory generalizing some of its well-known results to fuzzy setting. In addition, we provide illustrative examples of applications of the presented theory, namely, conceptual scaling to fuzzy attributes and use of block relation to reduce size of a concept lattice.We study relationships between compositions of fuzzy relations (for- mal fuzzy contexts) and morphisms of the structures (concept lat- tices) associated to the fuzzy relations.
