		sentence::iterator	start,
		sentence::iterator	end,
		int	fs,
		bool &	built,
		ner_status *	st

const [virtual]

pure virtual function to be provided by the child class .

Resets automaton internal variables when a new search is started.

Implements freeling::automat< ner_status >.

Reimplemented in freeling::np.

void freeling::ner_module::SetMultiwordAnalysis	(	sentence::iterator	i,
		int	fstate,
		const ner_status *	st

Member Data Documentation

unsigned int freeling::ner_module::AllCaps_Title_length [protected]

std::wstring freeling::ner_module::NE_tag [protected]

Tag to assign to detected NEs.

bool freeling::ner_module::splitNPs [protected]

if we want to split NEs, set this to true

unsigned int freeling::ner_module::Title_length [protected]

length beyond which a multiword made of all capitialized words ("WRECKAGE: TITANIC DISAPPEARS IN NORTHERN SEA") will be considered a title and not a proper noun.

A value of zero deactivates this behaviour.
