DESCRIPTION

DTA::CAB::Analyzer::LangId provides a DTA::CAB::Analyzer interface to the Lingua::LangId language-guessing library. Its current implementation only has proof-of-concept status.

Globals

Variable: @ISA

DTA::CAB::Analyzer::LangId inherits from DTA::CAB::Analyzer and implements the DTA::CAB::Analyzer API.

Constructors etc.

new
$obj = CLASS_OR_OBJ->new(%args);

object structure:

(
 ##-- Filename Options
 mapFile => $filename,     ##-- default: none (REQUIRED)
 ##-- Analysis Options
 analyzeWhich     => $which, ##-- one of 'token', 'sentence', 'document'; default='document'
 vlabel           => $label, ##-- verbose destination key (default='langid')
 label            => $label, ##-- simple destination key (default='lang')
 ##-- Analysis Objects
 map            => $map,   ##-- a Lingua::LangId::Map object
)
clear
$lid = $lid->clear();

(undocumented)

Methods: Generic

mapOk
$bool = $lid->mapOk();

  • should return false iff map is undefined or "empty"

  • default version checks for non-empty 'map' and 'sigs'

Methods: I/O: Input: all

ensureLoaded
$bool = $lid->ensureLoaded();

ensures model data is loaded from default files (if available)

Methods: I/O: Input: Map

loadMap
$lid = $lid->loadMap($map_file);

(undocumented)

Methods: Persistence: Perl

noSaveKeys
@keys = $class_or_obj->noSaveKeys();

returns list of keys not to be saved

loadPerlRef
$loadedObj = $CLASS_OR_OBJ->loadPerlRef($ref);

implicitly calls $obj->clear()

Methods: Analysis: Generic

canAnalyze
$bool = $anl->canAnalyze();

returns true if analyzer can perform its function (e.g. data is loaded & non-empty)

Methods: Analysis: Generic

analyzeThingy
$thingy = $lid->analyzeThingy($thingy, \$str, \%opts);

(undocumented)

Methods: Analysis: v1.x: API

analyzeDocument
$doc = $anl->analyzeDocument($doc,\%opts);

  • analyze a DTA::CAB::Document $doc

  • top-level API routine
