A Novel Concept Acquisition Approach Based on Formal Contexts

Algorithm 1

(1) input context,

(2) step = 1,

(3) get first step set (),

(4) intent set = former step set,

(5) step++,

(6) later step set ={𝛽∶𝛽= make arbitrary two ranks meet in the context},

(7) while (step ≤ max rank of context)  {former step set = later step set;

   intent set = union of later step set and intent set; step++;},

(8) output the set of intents.
