- Class
  Description
  DefaultLemmatizerContextGenerator
  Simple feature generator for learning statistical lemmatizers.
  DefaultLemmatizerSequenceValidator
  The default lemmatizer `SequenceValidator` implementation.
  DictionaryLemmatizer
  A `Lemmatizer` implementation that works by simple dictionary lookup into a `Map` built from a file containing, for each line:
  LemmaSample
  Represents a lemmatized sentence.
  LemmaSampleEventStream
  Class for creating an event stream out of data files for training a probabilistic `Lemmatizer`.
  LemmaSampleSequenceStream
  A `SequenceStream` implementation encapsulating `samples`.
  LemmaSampleStream
  Reads data for training and testing the `Lemmatizer`.
  Lemmatizer
  The common interface for lemmatizers.
  LemmatizerContextGenerator
  Interface for the context generator used for probabilistic `Lemmatizer`.
  LemmatizerEvaluationMonitor
  A marker interface for evaluating `lemmatizers`.
  LemmatizerEvaluator
  The `LemmatizerEvaluator` measures the performance of the given `Lemmatizer` with the provided reference `samples`.
  LemmatizerFactory
  The factory that provides `Lemmatizer` default implementation and resources.
  LemmatizerME
  A probabilistic `Lemmatizer` implementation.
  LemmatizerModel
  The `LemmatizerModel` is the model used by a learnable `Lemmatizer`.
  ThreadSafeLemmatizerME
  A thread-safe version of the `LemmatizerME`.
