| virtual statscore_t MosesTuning::StatisticsBasedScorer::calculateScore | ( | const std::vector< ScoreStatsType > & | totals | ) | const [protected, pure virtual] |
Calculate the actual score.
Implements MosesTuning::Scorer.
Implemented in MosesTuning::BleuScorer, MosesTuning::CderScorer, MosesTuning::HwcmScorer, MosesTuning::M2Scorer, MosesTuning::MeteorScorer, MosesTuning::PermutationScorer, MosesTuning::PerScorer, MosesTuning::SemposScorer, and MosesTuning::TerScorer.
Referenced by score().
| virtual float MosesTuning::StatisticsBasedScorer::getReferenceLength | ( | const std::vector< ScoreStatsType > & | totals | ) | const [inline, protected, virtual] |
Based on vector of sufficient statistics, return length of reference.
Implements MosesTuning::Scorer.
Reimplemented in MosesTuning::BleuScorer, MosesTuning::HwcmScorer, MosesTuning::M2Scorer, and MosesTuning::MeteorScorer.
