NAME

DTA::CAB::Analyzer::Morph::Helsinki - morphological analysis via Gfsm automata, for use with Helsinki-style transducers

SYNOPSIS

use DTA::CAB::Analyzer::Morph::Helsinki;

$morph = DTA::CAB::Analyzer::Morph::Helsinki->new(%args);
$morph->analyze($tok);

DESCRIPTION

DTA::CAB::Analyzer::Morph::Helsinki is a simplified wrapper for DTA::CAB::Analyzer::Automaton::Gfsm which sets the following default options:

##-- analysis selection
label => 'morph',        ##-- analysis output property
wantAnalysisLo => 0,     ##-- don't output lower label paths
tolower => 1,            ##-- bash input to lower-case

It also adds TAGH-style tag-extraction post-processing in its analyzeTypes() method.

Morphological transducers are available in HFST format for various languages from https://sourceforge.net/projects/hfst/files/resources/morphological-transducers/. In order to be used with this package, the HFST transducers must be converted to Gfsm format, and may require additional transducer-specific adjustments (e.g. alphabet conventions for tag-extraction heuristics).
