Text::Info - Retrieve information about, and do analysis on, text.
Version 0.01.
use Text::Info; my $text = Text::Info->new( "Some text..." ); say "The text is written in language '" . $text->language . "', and"; say "has a readability score (FRES) of " . $text->readability->fres;
Text::Info is an extensible and easy to use solution for retrieving useful information about texts based on the Germanic languages.
For the time being it has a limited feature set, but the plan is to use this as a basis for NLP-solutions.
The solution is under heavy development, and the API will definitely change. Please respect these facts if you intend to use it.
Contributions and suggestions are welcome!
This solution is - and will be - heavily based on language-specific features. This means that if you use this solution on languages that doesn't have the required "support modules", you're on your own. For the time being this only affects the Text::Info::Readability functionality, but will in the future also include stemming- and stop word-functionality (and probably many other things).
What you can do to help on this, is to create the missing supported modules, for example create a Lingua::__::Syllable module specific for your language.
Returns a new Text::Info object. Can take text as a single argument, optionally tld (top level domain, for better language detection), and/or optionally language if you want to specify the text's language yourself.
text
tld
language
my $text = Text::Info->new( 'Dette er en norsk tekst.' ); # ...or... my $text = Text::Info->new( text => 'Dette er en norsk tekst.', tld => 'no', ); # ...or... my $text = Text::Info->new( text => 'Dette er en norsk tekst.' language => 'no', );
It really doesn't make sense to set both tld and language, as the former is a helper for detecting the correct language of the text, while the latter overrides whatever that detection algorithm returns.
Returns an instance of the text's Text::Info::Readability class, which in turn can be used to retrieve readability information about the text in question.
Returns an array reference of the text's sentences as Text::Info::Sentence objects. This method is derived from Text::Info::BASE.
Text::Info::Sentence
Keep in mind that this method tries to remove any separators, so the sentences returned should NOT contain those. For example "This is a sentence!" will be returned as "This is a sentence".
Returns the number of sentences in the text. This method is derived from Text::Info::BASE.
Returns the average length of the sentences in the text. This method is derived from Text::Info::BASE.
Returns an array reference containing the text's words. This method is derived from Text::Info::BASE.
Returns the number of words in the text. This is a helper method and is derived from Text::Info::BASE.
Returns the average length of the words in the text. This is a helper method and is derived from Text::Info::BASE.
Returns an array reference containing the text's ngrams of size $size. Default size is 2 (i.e. bigrams). This method overrides Text::Info::BASE's ngrams() method, as it takes into accounts building ngrams based on the text's sentences, not the text's complete list of words.
$size
ngrams()
Returns an array reference containing the text's unigrams, i.e. the same as ngrams(1). This is a helper method and is derived from Text::Info::BASE.
ngrams(1)
Returns an array reference containing the text's bigrams, i.e. the same as ngrams(2). This is a helper method and is derived from Text::Info::BASE.
ngrams(2)
Returns an array reference containing the text's trigrams, i.e. the same as ngrams(3). This is a helper method and is derived from Text::Info::BASE.
ngrams(3)
Returns an array reference containing the text's quadgrams, i.e. the same as ngrams(4). This is a helper method and is derived from Text::Info::BASE.
ngrams(4)
Returns the number of syllables in the text. This method requires that Lingua::__::Syllable is available for the language in question. This method is derived from Text::Info::BASE.
