Interface Summary

Interface	Description
AdaptiveFeatureGenerator	An interface for generating features for name entity identification and for updating document level contexts.
ArtifactToSerializerMapper
FeatureGeneratorFactory	Deprecated do not use this interface, will be removed!
FeatureGeneratorResourceProvider	The FeatureGeneratorResourceProvider provides access to the resources provided in the model.

Class Summary

Class	Description
AdditionalContextFeatureGenerator	The AdditionalContextFeatureGenerator generates the context from the passed in additional context.
AggregatedFeatureGenerator	The AggregatedFeatureGenerator aggregates a set of AdaptiveFeatureGenerators and calls them to generate the features.
BigramNameFeatureGenerator
BrownBigramFeatureGenerator	Generates Brown cluster features for token bigrams.
BrownCluster	Class to load a Brown cluster document: word\tword_class\tprob http://metaoptimize.com/projects/wordreprs/ The file containing the clustering lexicon has to be passed as the value of the dict attribute of each BrownCluster feature generator.
BrownCluster.BrownClusterSerializer
BrownTokenClasses	Obtain the paths listed in the pathLengths array from the Brown class.
BrownTokenClassFeatureGenerator	Generates Brown cluster features for current token and token class.
BrownTokenFeatureGenerator	Generates Brown cluster features for current token.
CachedFeatureGenerator	Caches features of the aggregated AdaptiveFeatureGenerators.
CharacterNgramFeatureGenerator	The CharacterNgramFeatureGenerator uses character ngrams to generate features about each token.
CustomFeatureGenerator
DictionaryFeatureGenerator	The DictionaryFeatureGenerator uses the DictionaryNameFinder to generated features for detected names based on the InSpanGenerator.
DocumentBeginFeatureGenerator
FastTokenClassFeatureGenerator	Deprecated Use TokenClassFeatureGenerator instead!
FeatureGeneratorAdapter	This class provides empty implementations of some of the optional methods in AdditionalContextFeatureGenerator to make implementing feature generators easier.
FeatureGeneratorUtil	This class provide common utilities for feature generation.
GeneratorFactory	Creates a set of feature generators based on a provided XML descriptor.
InSpanGenerator	Generates features if the tokens are recognized by the provided TokenNameFinder.
OutcomePriorFeatureGenerator	The definition feature maps the underlying distribution of outcomes.
PrefixFeatureGenerator
PreviousMapFeatureGenerator	This FeatureGeneratorAdapter generates features indicating the outcome associated with a previously occuring word.
PreviousTwoMapFeatureGenerator	This FeatureGeneratorAdapter generates features indicating the outcome associated with two previously occuring words.
SentenceFeatureGenerator	This feature generator creates sentence begin and end features.
StringPattern	Recognizes predefined patterns in strings.
SuffixFeatureGenerator
TokenClassFeatureGenerator	Generates features for different for the class of the token.
TokenFeatureGenerator	Generates a feature which contains the token itself.
TokenPatternFeatureGenerator	Partitions tokens into sub-tokens based on character classes and generates class features for each of the sub-tokens and combinations of those sub-tokens.
TrigramNameFeatureGenerator	Adds trigram features based on tokens and token classes.
WindowFeatureGenerator	Generates previous and next features for a given AdaptiveFeatureGenerator.
WordClusterDictionary
WordClusterDictionary.WordClusterDictionarySerializer
WordClusterFeatureGenerator
