NAME

Lingua::YaTeA::TagSet - Perl extension for managing the set of Part-of-Speech tags and inflected that can be accepted in the terms.

SYNOPSIS

  use Lingua::YaTeA::TagSet;
  Lingua::YaTeA::TagSet->new();

DESCRIPTION

This module provides methods for managing a set of Part-of-Speech tags of inflected forms that can be accepted in the terms to extract. Such lists of tags or inflected form are used by the Parsing Patterns while the syntactic analusys of the maximal noun phrases. This information is generally stored in the c<TagSet> configuration file. The definition of the different classes is provided: CANDIDATES}(the content words), DETERMINERS (the determiner words), PREPOSITIONS (the preposition words) and COORDINATIONS (the coordination words).

METHODS

new()

    $file = "/home/thierry/YaTeAconfig/EN/TagSet";
    new($file);

This method creates an object with 5 fields CANDIDATES, PREPOSITIONS, DETERMINERS, COORDINATIONS, ANY and loads the tags contained in the file $file. The field ANY contains all the tags. A field designates a class of tags and is a hash table.

loadTags()

    loadTags($file);

This method opens the file $file and loads all the tagsets.

addTag()

    addTag($subset,$tag);

This method stores the tag $tag in the right class $subset.

getSubset()

    getSubset($subset);

This method returns the field of the current object that contains tags of the class $subset.

getTagList()

    getTagList($subset);

This method returns all the tags of the class $subset.

existTag()

    existTag($subset,$tag);

This methods indicates whether the tag $tag exists in the subset of tags $subset (it returns the value 1) or not (its returns the value 0). The field of the objet corresponding to the structure is set.

parseSubset()

    parseSubset($line);

This method parses a line containing the definition of a subset of tags. it sets the corresponding field in the object calling the method. In case of an error of format, the method dies.

makeALL()

    makeALL($subset, \@tags);

The method sets the field ALL of the subset $subset with the tags contained in the array \@tags given by reference. This field is a string containg a regex. Each tag is an alternative.

sort()

    sort(\@tags);

The method returns a regex where each element of the array given by reference is a alternative and is sorted.
