addFeatures

public void addFeatures(Collection<Integer> indices,
                        Predicate pred,
                        Word arg,

performFeatureExtraction

protected void performFeatureExtraction(Sentence s,
                                        boolean allWords)

Description copied from class: SingleFeature

This method works with features that have includeArgs==false. It extracts either from all words (if boolean allWords is true), or from the predicates only (if false)

Overrides:

performFeatureExtraction in class SingleFeature
