sentence::iterator ner_module::BuildMultiword	(	sentence &	se,
		sentence::iterator	start,
		sentence::iterator	end,
		int	fs,
		bool &	built
	)		[virtual]

Build a Multiword and sets its analysis.

Effectively build multiword, altering sentence.

Reimplemented from automat.

References util::is_capitalized(), and TRACE.

Referenced by bioner::analyze().

int ner_module::ComputeToken	(	int	,
		sentence::iterator &	,
		sentence &
	)		[virtual]

Allow classes under ner to be incomplete automata.

Implements automat.

Reimplemented in np.

void ner_module::ResetActions

(

)

[virtual]

pure virtual function to be provided by the child class .

Resets automaton internal variables when a new search is started.

Implements automat.

Reimplemented in np.

void ner_module::SetMultiwordAnalysis	(	sentence::iterator	i,
		int	fstate
	)		[virtual]

Set the appropriate lemma and tag for the new multiword.

Implements automat.

Reimplemented in np.

References TRACE.

void ner_module::StateActions	(	int	,
		int	,
		int	,
		sentence::const_iterator
	)		[virtual]

pure virtual function to be provided by the child class.

Performs appropriate internal actions, given origin and destinanation states, token code and word.

Implements automat.

Reimplemented in np.

bool ner_module::ValidMultiWord

(

const word &

w

)

[virtual]

Perform last minute validation before effectively building multiword.

Member Data Documentation

unsigned int ner_module::AllCaps_Title_length [protected]

std::wstring ner_module::NE_tag [protected]

Tag to assign to detected NEs.

bool ner_module::splitNPs [protected]

if we want to split NEs, set this to true

unsigned int 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.
