classify

public String classify(List<org.cleartk.ml.Feature> features)

Description copied from class: RelationExtractorAnnotator

Predict an outcome given a set of features. By default, this simply delegates to the object's classifier. Subclasses may override this method to implement more complex classification procedures.

Overrides:

classify in class RelationExtractorAnnotator

Parameters:

features - The features to be classified.

Returns:

The predicted outcome (label) for the features.
