virtual void Parser::Parser::revise	(	SentenceReader *	sentenceReader,
		char const *	actionFile = 0
	)			[inline, virtual]

Produce a revision of a document parses, using either a model or an action file.

If an actionFile is provided, it must contain a list of actions, one per line, to apply to the parse trees, otherwise the actions to perform revisions are determined using the model.

Reimplemented in Parser::ApParser, Parser::MeParser, and Parser::MlParser.

Definition at line 111 of file Parser.h.

void Parser::Parser::showEval	(	int	tokenCount,
		int	las,
		int	uas,
		int	sentCount
	)			[virtual]

Print accuracy estimates.

Definition at line 237 of file Parser.cpp.

void Parser::Parser::writeHeader

(

std::ostream &

os

)

Write model header to stream.

Parameters:

os
