Type Members

1. case class AnchoredPCFGProjector[L, W](threshold: Double = scala.Double.NegativeInfinity) extends ChartProjector[L, W] with Product with Serializable

   Creates a locally-normalized anchored PCFG from some refined forest.

2. case class AnchoredRuleMarginalProjector[L, W](threshold: Double = scala.Double.NegativeInfinity) extends ChartProjector[L, W] with Product with Serializable

   Creates anchorings for a set of trees from some parser using p(rule | sentence) marginals.

3. class AnchoredRuleProjector extends Serializable

   Used for computed the expected number of anchored rules that occur at each span/split.

4. class AnchoredSpanProjector extends Serializable

   Used for computed the expected number of anchored labels that occur at each span

5. trait ChartProjector[L, W] extends AnyRef

   Projects a chart to a span anchoring

6. case class EnumeratedAnchoring[L, W](topology: RuleTopology[L], lexicon: Lexicon[L, W], words: IndexedSeq[W], spanScores: Array[OpenAddressHashArray[Double]], unaryScores: Array[OpenAddressHashArray[Double]], binaryScores: Array[Array[OpenAddressHashArray[Double]]], sparsityPattern: ChartConstraints[L]) extends UnrefinedGrammarAnchoring[L, W] with Serializable with Product with Serializable

   An epic.parser.projections.EnumeratedAnchoring is a compressed forest, with potentially distinct rule and span scores for every possible anchoring.

7. trait GoldTagPolicy[L] extends AnyRef

8. final case class GrammarRefinements[C, F](labels: ProjectionIndexer[C, F], rules: ProjectionIndexer[Rule[C], Rule[F]]) extends Product with Serializable

9. case class LabeledSpanProjector[L, W](topology: RuleTopology[L], threshold: Double = scala.Double.NegativeInfinity) extends ChartProjector[L, W] with Product with Serializable

   Creates a grammar using only span marginals and unary rule marginals

10. class OracleParser[L, L2, W] extends SafeLogging

    Finds the best tree (relative to the gold tree) s.

11. class ParserChartConstraintsFactory[L, W] extends Factory[L, W] with Serializable with SafeLogging

    Creates labeled span scorers for a set of trees from some parser.

12. case class ProjectingCoreGrammar[L, W](parser: Parser[L, W], projector: ChartProjector[L, W]) extends Grammar[L, W] with Product with Serializable

13. final class ProjectionIndexer[C, F] extends (Int) ⇒ Int with Serializable

    For computing projections from a fine grammar to a coarse grammar.

14. case class ProjectionParams(treebank: ProcessedTreebank, parser: File, out: File = ..., name: String = "parseConstraints", maxParseLength: Int = 80, threshold: Double = -7) extends Product with Serializable

15. case class SpanAnchoring[L, W](topology: RuleTopology[L], lexicon: Lexicon[L, W], words: IndexedSeq[W], sparsityPattern: ChartConstraints[L], spanScores: Array[OpenAddressHashArray[Double]], unaryScores: Array[OpenAddressHashArray[Double]]) extends UnrefinedGrammarAnchoring[L, W] with Product with Serializable
