public interface AdaptiveFeatureGeneratorAn interface for generating features for name entity identification and for updating document level contexts.
Feature generation is not thread safe and a instance of a feature generator must only be called from one thread. The resources used by a feature generator are typically shared between man instances of features generators which are called from many threads and have to be thread safe.
All Methods Instance Methods Abstract Methods Default Methods Modifier and Type Method Description
clearAdaptiveData()Informs the feature generator that the context of the adaptive data (typically a document) is no longer valid.
createFeatures(List<String> features, String tokens, int index, String previousOutcomes)Adds the appropriate features for the token at the specified index with the specified array of previous outcomes to the specified list of features.
updateAdaptiveData(String tokens, String outcomes)Informs the feature generator that the specified tokens have been classified with the corresponding set of specified outcomes.
features- The list of features to be added to.
tokens- The tokens of the sentence or other text unit being processed.
index- The index of the token which is currently being processed.
previousOutcomes- The outcomes for the tokens prior to the specified index.
tokens- The tokens of the sentence or other text unit which has been processed.
outcomes- The outcomes associated with the specified tokens.
