Detailed Description

Discriminatively trained global lexicon model This is a implementation of Mauser et al., 2009's model that predicts each output word from _all_ the input words. The intuition behind this feature is that it uses context words for disambiguation

Member Function Documentation

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

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

Reimplemented from Moses::StatelessFeatureFunction.

Definition at line 182 of file GlobalLexicalModel.cpp.

References Moses::PhraseBasedFeatureContext::GetTargetPhrase(), and Moses::ScoreComponentCollection::PlusEquals().

Here is the call graph for this function:

void Moses::GlobalLexicalModel::EvaluateChart	(	const ChartBasedFeatureContext &	context,
		ScoreComponentCollection *	accumulator
	)			const `[inline, virtual]`

Same for chart-based features.

Reimplemented from Moses::StatelessFeatureFunction.
