Abstract :
FCA is applied into Q-matrix theory and modifies that Q is Boolean algebra in terms of Boolean addition, Boolean multiplication, and complement operator Tatsuoka 1991 1995. The structure of item tree Tatsuoka 1995 is denied, and the concept lattices are constructed which is derived from Q matrix.
