public interface LexicalSmoother

Interface for a lexical smoother.

A lexical smoother computes the lexically smoothed probabability of a word given a part of speech tag, e.g., p( word | tag ).

Method Summary

Methods

Method Detail

setPartOfSpeechTagger

void setPartOfSpeechTagger(PartOfSpeechTagger posTagger)

Set the part of speech tagger for this smoother.

Parameters:

posTagger - Part of speech tagger for which this smoother provides probabilities.

cachedProbabilitiesCount

int cachedProbabilitiesCount()

Get the number of cached lexical probabilities.

Returns:

The number of cached lexical probabilities.

clearCachedProbabilities

void clearCachedProbabilities()

Clear cached probabilities..

lexicalProbability

Probability lexicalProbability(java.lang.String word,
                             java.lang.String tag)

Get lexically smoothed probability of a word given a tag.

Parameters:

word - The word.

tag - The part of speech tag.

Returns:

Lexically smoothed probability of word given tag, e.g., p( word | tag ).
