Description

Interface Summary

AdaptiveFeatureGenerator	An interface for generating features for name entity identification and for updating document level contexts.
FeatureGeneratorFactory	The FeatureGeneratorFactory interface is factory for AdaptiveFeatureGenerators.
FeatureGeneratorResourceProvider	The FeatureGeneratorResourceProvider provides access to the resources provided in the model.

Class Summary

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.
CachedFeatureGenerator	Caches features of the aggregated AdaptiveFeatureGenerators.
CharacterNgramFeatureGenerator	The CharacterNgramFeatureGenerator uses character ngrams to generate features about each token.
DictionaryFeatureGenerator	The DictionaryFeatureGenerator uses the DictionaryNameFinder to generated features for detected names based on the InSpanGenerator.
FastTokenClassFeatureGenerator	Generates features for different for the class of the token.
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.
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.
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.
WindowFeatureGenerator	Generates previous and next features for a given AdaptiveFeatureGenerator.
