Don't know anything about SAPIS. I guess you are trying to print out the hash or convert it to a some sort of string to view the match. For starters you can use Data::Dumper.

The error message is telling you the $result is a hash ref so you need to treat it as hash to view the contents. Here is an example -

#!/usr/bin/perl

use strict;
use warnings;
use Data::Dumper;

my $result = { 'word1' => 1, 'word2'  => 1};

print Dumper ($result);

# manual printing

print $_, " => " , $result->{$_},$/ for (keys %$result); # note the %$

Output

$VAR1 = {
          'word2' => 1,
          'word1' => 1
        };
word2 => 1
word1 => 1

BTW check out QandASection: hashes for more information on hashes.
