Member Function Documentation

add_declaration()

void CGNTagger::add_declaration ( folia::Document &  doc, folia::processor *  proc  ) const

virtual

add POS annotation as an AnnotationType to the document

Parameters

doc	the Document the add to
proc	the processor to add

Implements BaseTagger.

add_tags()

void CGNTagger::add_tags	(	const std::vector< folia::Word * > &	wv,
		const frog_data &	fd
	)		const

add the tagger results to the folia:Word list

Parameters

wv	The folia::Word vector to add to
fd	the frog_data structure with the tagger results

getSubSet()

string CGNTagger::getSubSet	(	const std::string &	val,
		const std::string &	head,
		const std::string &	fullclass
	)		const

get a specific subset value. (FoLiA output only)

Parameters

val	the val to look up
head	the head of the CGN POS-tag
fullclass	the original full CGN tag, used for error messages only

Returns

a string with the found value or throws when there is a problem

Note

for a well-trained CGN tagger, all values should belong to a subset AND there may never be a constraints conflict

A full class may be N(soort,ev,basis,zijd,stan), so the head is N.

For every value in 'soort,ev,basis,zijd,stan' we lookup the subset in the cgn_subsets, and when the constraints on the head are satisfied we return the subset.

For instance: 'soort' is found in the subsets to belong to the subset 'ntype' and there are no 'head' constrainst on ntype, so the lookup for 'soort' yields 'ntype'

And would the fullclass have been VNW(betr,pron,stan,vol,persoon,getal) then the subset for 'getal' is 'getal' AND the constraints for 'getal' are 'VNW, N', so these are satisfied and the result is 'getal'

init()

bool CGNTagger::init ( const TiCC::Configuration &  config )

virtual

initalize a CGN tagger from 'config'

Parameters

config

the TiCC::Configuration

Returns

true on succes, false otherwise

first BaseTagger::init() is called to set generic values, then the CGN specific values for subset and constraints file-names are added and those files are read, except when these have the value 'ignore'

Reimplemented from BaseTagger.

post_process()

void CGNTagger::post_process ( frog_data &  words )

virtual

add the found tagging results to the frog_data structure

Parameters

words

The frog_data structure to extend

Implements BaseTagger.
