Method Detail

getProbabilities

SubsetProbabilities[] getProbabilities(String[][] wordsets,
                                       SegmentationDefinition[] definitions)

Estimates the probabilities for the given word sets and the given segmentations.

Parameters:

wordsets - word sets for which the probabilities should be estimated

definitions - definitions how the word sets should be separated

Returns:

the subset probabilities for the single word sets

getFrequencyDeterminer

FrequencyDeterminer getFrequencyDeterminer()

Returns the frequency determiner used by this estimator.

Returns:

the frequency determiner used by this estimator

setFrequencyDeterminer

void setFrequencyDeterminer(FrequencyDeterminer determiner)

Sets the frequency determiner that should be used by this estimator.

Parameters:

determiner - the frequency determiner used by this estimator

getName

String getName()

Returns the name of this probability estimator.

Returns:

the name of this probability estimator

setMinFrequency

void setMinFrequency(int minFrequency)

Sets the minimum frequency a word (or word set) must have to get a probability > 0.

Parameters:

minFrequency - the minimum frequency of a word
