A Novel Concept Acquisition Approach Based on Formal Contexts

Algorithm 2

(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)  {if (later step set is not the subset of

   former step set)  {former step set = later step set; intent set = union of

   later step set and intent set; step++;} else {return}},

(8) output the set of intents.
