  • Method Details

    • 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
