You should also enable warnings and strictures to let Perl help you find mistakes.

open( FILE, "< $ARGV[0]" );
[download]

You should always verify that the file opened correctly.

open FILE, '<', $ARGV[ 0 ] or die "Cannot open '$ARGV[ 0 ]' $!";
[download]

while ( <FILE> ) {

        my $line = $_;

        chomp ($line);
        my @word = split / /, $line;
[download]

Or simply:

while ( my $line = <FILE> ) {
        chomp $line;
        my @word = split ' ', $line;
[download]

        $count = 0;
        while ( $word[ $count ] ) {
                $word[ $count ] =~ tr/^[\-a-zA-Z]//;
                $word[ $count ] =~ s/\'/\\\'/g;
                $count++;
        }
[download]

That is usually written as:

        for ( @word ) {
                tr/^[\-a-zA-Z]//;
                s/\'/\\\'/g;
        }
[download]

But tr/^[\-a-zA-Z]// doesn't do anything in this context so why is it there?

while ( $key = keys %uword ) {
[download]

That looks like you should be using each instead of keys as that produces an infinite loop.
