public static class CleartkExtractor.Focus extends Object implements CleartkExtractor.Context
CleartkExtractor.Context for extracting the focus annotation. This is mainly useful when the focus
annotation should be combined with other annotations using, e.g. a CleartkExtractor.Bag or CleartkExtractor.Ngram
to aggregate over several contexts.| Constructor and Description |
|---|
CleartkExtractor.Focus()
Constructs a context that will extract features over the focus annotation.
