Interface Summary

Chunk	The Chunk interface specifies a slice of a character sequence, a chunk type and a chunk score.
Chunker	The Chunker interface specifies methods for returning a chunking given a character sequence or character slice.
Chunking	The Chunking interface specifies a set of chunks over a shared underlying character sequence.
ConfidenceChunker	The ConfidenceChunker interface specifies a method for returning an iterator over chunks in order of confidence.
NBestChunker	An NBestChunker is a chunker that is able to return results iterating over scored chunkings or scored chunks in order of decreasing likelihood.

Class Summary

AbstractCharLmRescoringChunker<B extends NBestChunker,O extends LanguageModel.Process,C extends LanguageModel.Sequence>	An AbstractCharLmRescoringChunker provides the basic character language-model rescoring model used by the trainable CharLmRescoringChunker and its compiled version.
CharLmHmmChunker	A CharLmHmmChunker employs a hidden Markov model estimator and tokenizer factory to learn a chunker.
CharLmRescoringChunker	A CharLmRescoringChunker provides a long-distance character language model-based chunker that operates by rescoring the output of a contained character language model HMM chunker.
ChunkAndCharSeq	The ChunkAndCharSeq is an immutable composite of a chunk and a character sequence.
ChunkerEvaluator	The ChunkerEvaulator class provides an evaluation framework for chunkers.
ChunkFactory	The ChunkFactory provides static factory methods for creating chunks from components.
ChunkingEvaluation	A ChunkingEvaluation stores and reports the results of evaluating response chunkings against reference chunkings.
ChunkingImpl	A ChunkingImpl provides a mutable, set-based implementation of the chunking interface.
HmmChunker	An HmmChunker uses a hidden Markov model to perform chunking over tokenized character sequences.
RegExChunker	A RegExChunker finds chunks that matches regular expressions.
RescoringChunker<B extends NBestChunker>	A RescoringChunker provides first best, n-best and confidence chunking by rescoring n-best chunkings derived from a contained chunker.
TokenShapeChunker	A TokenShapeChunker uses a named-entity TokenShapeDecoder and tokenizer factory to implement entity detection through the chunk.Chunker interface.
TrainTokenShapeChunker	A TrainTokenShapeChunker is used to train a token and shape-based chunker.
