Detailed Description

to keep track of the various things that can produce a score, we use this evil implementation-inheritance to give them each a unique, sequential (read: good for vector indices) ID

Note:

do not confuse this with a producer/consumer pattern. this is not a producer in that sense.

[inline]

virtual size_t Moses::ScoreProducer::GetNumInputScores

(

)

const [inline, virtual]

returns the number of scores gathered from the input (0 by default)

Reimplemented in Moses::DistortionScoreProducer, Moses::WordPenaltyProducer, Moses::UnknownWordPenaltyProducer, and Moses::PhraseDictionaryFeature.

virtual size_t Moses::ScoreProducer::GetNumScoreComponents

const [pure 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

virtual std::string Moses::ScoreProducer::GetScoreProducerWeightShortName

(

)

const [pure virtual]

returns the weight parameter name of this producer (used in n-best list)

Implemented in Moses::DistortionScoreProducer, Moses::WordPenaltyProducer, Moses::UnknownWordPenaltyProducer, Moses::GenerationDictionary, Moses::GlobalLexicalModel, Moses::LanguageModel, Moses::LexicalReordering, and Moses::PhraseDictionaryFeature.
