【Abstract】 The core attribute of a strongly decision formal context by the closed label of a concept was studied.Using the closed label of a concept,a method of judging a set whether if is a consistent set of the strongly decision formal context was given.Further,a function of computing the reductions was defined,and the reduction set was obtained.Finally,through a collection of simple set operations,the core attribute of the strongly decision formal context was achieved.更多还原
