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 TargetPhrase &	cur_hypo,
		ScoreComponentCollection *	accumulator
	)			const [virtual]

Evaluate for stateless feature functions. Implement this.

Reimplemented from Moses::StatelessFeatureFunction.

const [inline, virtual]

returns the number of scores that a subclass produces. For example, a language model conventionally produces 1, a translation table some arbitrary number, etc

Implements Moses::ScoreProducer.
