Re^3: makeing refering faster ? by perldeveloper (Scribe) on Aug 16, 2004 at 15:23 UTC
Well, I'm answering now... You'd need to change the code to place information about the words that bind the sentences among each other inside the `@temp` array. This means something like this: `my %referencedSentences = (); foreach my $j (@{$words[$i]}) { if (($j ne "$j") \|\| ($j ne "v")) { if (exists $sentences->{$j}) { %referencedSentences{%j} = $sentences->{$j}; } } } push (@temp, \%referencedSentences);` [download] So, to clarify, here is the logical structure of the `@temp` array: `@temp` contains the sentence no. `i` at position `2 * i` and a hash indexed by words that other sentences start with at position `2 * i + 1`. Assume sentence `my $sentence = $temp[2 * 10]` and its hash `my $hash = $temp[2 * 10 + 1]` The hash contains all words in the sentence that other sentences start with. You can get a list of these words like this: `my @listOfWordsOtherSentencesStartWith = keys %{$hash}`. Say a word (`my $word`) belongs to this list of words. Then, `$hash->{$word}` returns a reference to an array that contains the indices (starting from `0`) of all sentences that start with word `$word`. So to get a list of these sentences, you'd write: `my @listOfSentencesThatStartWithThisWord = @{$hash->{$word}}` To get a list of all sentences referenced by a sentence, you'd write something like `my @list; foreach my $refToIndicesArray (values %{$hash}) { push (@list, @{$refToIndicesArray}); }` [download] I hope that answers your questions and good luck with your Perl project. Don't hesitate to ask again, though.	[reply] [d/l] [select]

@temp

    my %referencedSentences = ();
    foreach my $j (@{$words[$i]}) {
        if (($j ne "$j") || ($j ne "v")) {
            if (exists $sentences->{$j}) {
                %referencedSentences{%j} = $sentences->{$j};
            }
        }
    }
    push (@temp, \%referencedSentences);

@temp

@temp contains the sentence no. i at position 2 * i and a hash indexed by words that other sentences start with at position 2 * i + 1. Assume sentence my $sentence = $temp[2 * 10] and its hash my $hash = $temp[2 * 10 + 1]
The hash contains all words in the sentence that other sentences start with. You can get a list of these words like this: my @listOfWordsOtherSentencesStartWith = keys %{$hash}. Say a word (my $word) belongs to this list of words. Then, $hash->{$word} returns a reference to an array that contains the indices (starting from 0) of all sentences that start with word $word. So to get a list of these sentences, you'd write: my @listOfSentencesThatStartWithThisWord = @{$hash->{$word}}

To get a list of all sentences referenced by a sentence, you'd write something like

my @list;
foreach my $refToIndicesArray (values %{$hash}) {
   push (@list, @{$refToIndicesArray});
}
