Member Function Documentation

virtual void Moses::StatelessFeatureFunction::Evaluate	(	const PhraseBasedFeatureContext &	context,
		ScoreComponentCollection *	accumulator
	)			const [pure virtual]

This should be implemented for features that apply to phrase-based models.

Implemented in Moses::WordPenaltyProducer, Moses::UnknownWordPenaltyProducer, Moses::MetaFeatureProducer, Moses::GenerationDictionary, Moses::GlobalLexicalModel, Moses::PhraseLengthFeature, Moses::PhrasePairFeature, MockStatelessFeatureFunction, Moses::SourceWordDeletionFeature, Moses::TargetWordInsertionFeature, Moses::PhraseDictionary, and Moses::WordTranslationFeature.

Referenced by Moses::Hypothesis::EvaluateWith().

Here is the caller graph for this function:

virtual void Moses::StatelessFeatureFunction::EvaluateChart	(	const ChartBasedFeatureContext &	context,
		ScoreComponentCollection *	accumulator
	)			const [pure virtual]

Same for chart-based features.

Implemented in Moses::WordPenaltyProducer, Moses::UnknownWordPenaltyProducer, Moses::MetaFeatureProducer, Moses::GenerationDictionary, Moses::GlobalLexicalModel, Moses::PhraseLengthFeature, Moses::PhrasePairFeature, MockStatelessFeatureFunction, Moses::SourceWordDeletionFeature, Moses::TargetWordInsertionFeature, Moses::PhraseDictionary, and Moses::WordTranslationFeature.
