Input

Domain text;

Output

Domain word set dw[];

Step1

Initializations:spaces number ns; MI_2,threshold; compound word cw[];

Step2

Get MI_i,threshold = MI_2,threshold;

Step3

Calculate MI_3,threshold and MI_4,threshold with formula (7);

For (int i = 1; I < n; i++)

Step4

Get cw set [n];

Step5

Calculate ns_i;

Step6

Calculate MI_i with formula (3~5)；

Step7

If (MI_i > MI_i,threshold)

{dw[] = cw_i;}

End
