The split in 

my @word = split " ", $_;

[download]
could be rewritten as 
my @words = 
    map { lc }          # convert to lower case
    split /[\s.]+/, $_; # split on white space and "."

[download]
this will have the effect of removing all white space and periods and giving a list of lower case words. You need to read it backwards, the split happens before the map.
