Thanks a lot! very good points! I agree for the "sub to_hash" but for the "sub MI", I dont want the count of keys for hashes. instead of 
my $prob_es = ( keys %$hash_es ) / 6939873;
my $prob_en = ( keys %$hash_en ) / 6939873;

I want : 
my $prob_es = ( $#{$hash_es{$string_es}} + 1) / 6939873;
my $prob_en = ( $#{$hash_es{$string_en}} + 1 ) / 6939873;

[download]
which is the number of elements of the value array of each key!

The same goes for MI, I need the intersection between the array of both value arrays for the keys to thw two hashes.
