Beschreibung aus Schnittstelle kopiert: BeamSearchContextGenerator

Returns the context for the specified position in the specified sequence (list).

Angegeben von:

getContext in Schnittstelle BeamSearchContextGenerator<String>

Parameter:

index - The index of the sequence.

sequence - The sequence of items over which the beam search is performed.

priorDecisions - The sequence of decisions made prior to the context for which this decision is being made.

additionalContext - Any additional context specific to a class implementing this interface.

Beschreibung aus Schnittstelle kopiert: LemmatizerContextGenerator

Returns the contexts for lemmatizing of the specified index.

Angegeben von:

getContext in Schnittstelle LemmatizerContextGenerator

Parameter:

index - The index of the token in the specified toks array for which the context should be constructed.

toks - The tokens of the sentence. The toString() methods of these objects should return the token text.

tags - The POS tags for the specified toks.

preds - The previous decisions made in the tagging of this sequence. Only indices less than i will be examined.

Gibt zurück:

An array of predictive contexts on which a model basis its decisions.
