Are you sure you don't mean an array? How would you break the words up into keys and values? If you just want to stuff values into the keys of the hash (with '1' as the value), the basic form looks like this: 
my $sentence = 'This is a test';
my %hash = map { $_, 1 } ($sentence =~ /\w+/g);

If you need a count, you could do this: 
my $sentence = 'This is a test';
my %hash;
for ($sentence =~ /\w+/g) {
    $hash{ $_ }++;
}
