                                              SegmentationDefinition[] definitions)

Description copied from interface: ProbabilityEstimator

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

Specified by:

getProbabilities in interface ProbabilityEstimator

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
