Package edu.nyu.jet.hmm

The HMM package includes the classes for Hidden Markov Models, and part-of-speech and name taggers implemented using HMMs. A separate description is available of the overall structure and external representation of these models, provided for those who wish to modify the models.

Class Summary

Class	Description
ActiveLearner
ActiveLearnerTool
BasicHMMemitter	a simple HMMemitter, with statistics based only on exact match to a token in the training corpus.
BigramHMMemitter	an HMMemitter, using statistics for exact token match (including case), for token match (ignoring case), for token bigrams (ignoring case) and for word 'shape'.
BIOWriter	converts an XML-annotated named entity file (with the tag ENAMEX) into a BIO-format file.
HMM	A Hidden Markov Model.
HMMannotator	HMMAnnotator provides methods for training and using HMMs with annotated Documents.
HMMarc	an arc (from one state to another) in a Hidden Markov Model.
HMMemitter	this abstract class specifies the methods required for any class which computes the emission probabilities for an HMM.
HMMNameTagger	a Named Entity tagger based on the generic HMM (Hidden Markov Model) mechanism.
HMMstate	a state of a Hidden Markov Model.
HMMTagger	a POS (part-of-speech) tagger using a bigram model.
LineByLineNameTagger	reads a series of files, with each file containing one sentence per line, and writes out the sentences with named entity tags.
Retagger	class Retagger provides methods for converting Penn part-of-speech tags into Jet part-of-speech tags, and using the result to filter the entries in the Jet lexicon.
SuffixHMMemitter	an HMMemitter, using statistics for exact token match (including case), for token match (ignoring case), for suffix, and for word 'shape'.
WordFeatureHMMemitter	an HMMemitter, using statistics for exact token match (including case), for token match (ignoring case), and for word 'shape'.
XNameTagger	A modified version of HMMNameTagger for experiments with N-best tagging.
