Module Version: 0.08663   Source   Latest Release: Treex-Core-0.08664

NAME ^

Treex::Core::BundleZone - contains a sentence and its linguistic representations

VERSION ^

version 0.08663

SYNOPSIS ^

 use Treex::Core;
 my $doc = Treex::Core->new;
 my $bundle = $doc->create_bundle();
 my $zone = $bundle->create_zone('en','reference');
 $zone->set_sentence('John loves Mary.');

DESCRIPTION ^

Document zones allow Treex documents to contain more texts, typically parallel texts (translations), or corresponding texts from different sources (text to be translated, reference translation, test translation).

ATTRIBUTES ^

Treex::Core::BundleZone instances have the following attributes:

language
selector
sentence

The attributes can be accessed using semi-affordance accessors: getters have the same names as attributes, while setters start with set_. For example, the attribute sentence has a getter sentence() and a setter set_sentence($sentence)

METHODS ^

Construction

Treex::Core::BundleZone instances should not be created by the constructor, but should be created exclusively by calling one of the following methods of the embedding Treex::Core::Bundle instance:

create_zone
get_or_create_zone

Access to trees

There are four types of linguistic trees distinguished in Treex, each of them represented by one letter: a - analytical treex, t - tectogrammatical trees, p - phrase-structure trees, n - named entity trees. You can create trees by following methods:

$zone->create_tree($layer);
$zone->create_atree();
$zone->create_ttree();
$zone->create_ptree();
$zone->create_ntree();

You can access trees by

$zone->get_tree($layer);
$zone->get_atree();
$zone->get_ttree();
$zone->get_ptree();
$zone->get_ntree();
$zone->get_all_trees();

Presence of a tree of a certain type can be detected by

$zone->has_tree($layer);
$zone->has_atree();
$zone->has_ttree();
$zone->has_ptree();
$zone->has_ntree();

You can remove trees by

$zone->remove_tree($layer);

Access to embedding objects

$bundle = $zone->get_bundle();

returns the Treex::Core::Bundle instance which the zone belongs to

$doc = $zone->get_document();

returns the Treex::Core::Document instance which the zone belongs to

Other

$zone1 = $zone0->copy($selector1);

creates a copy of the zone (currently copies only the a-tree) under the same language and a new selector
