ClassDescriptionAn interface for generating features for name entity identification and for updating document level contexts.The
AdditionalContextFeatureGeneratorgenerates the context from the passed in additional context.TheAggregatedFeatureGeneratoraggregates a set ofAdaptiveFeatureGenerators and calls them to generate the features.Generates Brown cluster features for token bigrams.Class to load a Brown cluster document: word\tword_class\tprobGenerates Brown clustering features for token bigrams.Generates Brown clustering features for token classes.Generates Brown clustering features for current token.Obtain the paths listed in the pathLengths array from the Brown class.GeneratesBrownClusterfeatures for current token and token class.GeneratesBrownClusterfeatures for current token.Caches features of the aggregatedgenerators.TheCharacterNgramFeatureGeneratoruses character ngrams to generate features about each token.TheDictionaryFeatureGeneratoruses theDictionaryNameFinderto generated features for detected names based on theInSpanGenerator.TheFeatureGeneratorResourceProviderprovides access to the resources available in the model.This class provide common utilities for feature generation.Creates a set of feature generators based on a provided XML descriptor.Generates features if the tokens are recognized by the providedTokenNameFinder.The definition feature maps the underlying distribution of outcomes.Adds the token POS Tag as feature.ThisAdaptiveFeatureGeneratorgenerates features indicating the outcome associated with a previously occurring word.ThisAdaptiveFeatureGeneratorgenerates features indicating the outcome associated with two previously occurring words.This feature generator creates sentence begin and end features.Recognizes predefined patterns in strings.Generates features for the class of the token.Generates a feature which contains the token itself.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.Adds trigram features based on tokens and token classes.Generates previous (left-sided) and next (right-sided) features for a givenAdaptiveFeatureGenerator.AnAdaptiveFeatureGeneratorimplementation of a word cluster feature generator.Defines a word cluster generator factory; it reads an element containing 'w2vwordcluster' as a tag name.
