DESCRIPTION

DTA::CAB::Analyzer::DmootSub provides a DTA::CAB::Analyzer subclass for type-wise chained analysis of token-wise disambiguated input. Specifically, it was designed to invoke a morphological analyzer ('morph') on the output of a dynamic lexicon HMM ('dmoot'). This class inherits from DTA::CAB::Chain and implements the DTA::CAB::Analyzer API.

Methods: Constructors etc.

new

 $obj = $CLASS_OR_OBJ->new(chain=>\@analyzers, %args);

%$obj, %args (see also DTA::CAB::Chain):

 chain => [$a1, ..., $aN],    ##-- sub-analysis chain (e.g. chain=>[$morph,$mlatin])
 dmootLabel => $label,        ##-- label of source dmoot object (default='dmoot')
 standalone => $bool,         ##-- if true, no sub-analysis or morph parsing will be done (default=false)

Methods: I/O

chain

 \@analyzers = $ach->chain();
 \@analyzers = $ach->chain(\%opts);

Get selected analyzer chain. NEW: just return $ach->{chain}, since analyzers may still be disabled here (argh)

ensureLoaded

 $bool = $ach->ensureLoaded();

Returns true if any chain member loads successfully (or if the chain is empty). Hack: removes undefined chain-links before attempting to load sub-analyzers.

Methods: Analysis

doAnalyze

 $bool = $anl->doAnalyze(\%opts, $name);

Override: only allow analyzeSentences().

analyzeSentences

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

Post-processing for 'dmoot' object. Extracts dmoot targets, builds pseudo-type hash, calls sub-chain analyzeTypes(), & expands back into 'dmoot' sources.

typeKeys

 @keys = $anl->typeKeys();

Returns list of type-wise keys to be expanded for this analyzer by expandTypes(). Override returns empty list.

Methods: Analysis: Generic

canAnalyze

 $bool = $ach->canAnalyze();
 $bool = $ach->canAnalyze(\%opts)

Returns true if analyzer can perform its function (e.g. data is loaded & non-empty). Override always returns 1 because of 'toka' hack.

enabled

 $bool = $anl->enabled(\%opts);

Returns true if just $anl is enabled, even if no sub-analyzers are enabled.
