Hello perl monk.

This is "synlink" table of WordNet. Like this.

synset1    synset2    link
07125096-n 07128527-n hype
07126228-n 07109847-n hype
...

I thought I would like to overview how synsets link each other. For that, I have to do a recursive call and it took too much cost for querying SQLite each time, so I load it to a hash like this.

'07125096-n' => [ ['07128527-n', 'hype'], ..... ]
[download]

When I load it from database, it took about 3.6 secs. And I found loading from text file is far faster, and it took about 1.2 secs. Here I almost satisfied, but I would like to ask for monk's wisdom.

My Question is: 1) Is there a faster way ? 2) Please give me advice when you have experience for wordnet.

My fastest script is simple like below.(commented out for HiRes wrapping my time module)

use strict;
use warnings;
#use Data::Dumper;
#use MyTime;

    my $href={};
    #my $timeinf=MyTime->new();
    #$timeinf->push('before open');
    open(my $fh, "<", "04.txt") or die $!; 
    while(<$fh>){
        chomp;
        push @{ $href->{ substr($_,0,10)} }, [ substr($_,10,10), subst
+r($_,20)];
    }
    close $fh;
    #$timeinf->push('after load');
    #print $timeinf->as_string;

    print "count=", scalar keys %{$href} ,"\n";
    #print "test item:" , Dumper $href->{'01785341-a'} , "\n\n";

I put sample text file at here.
