public interface Dependency<G extends Label,D extends Label,N>
An individual dependency between a governor and a dependent.
The governor and dependent are represented as a Label.
For example, these can be a
Word or a WordTag. If one wishes the dependencies to preserve positions
in a sentence, then each can be a LabeledConstituent or CoreLabel.
Dependencies support an Object naming the dependency type. This may be
null. Dependencies have factories.
