Package edu.stanford.nlp.trees

Class UnnamedConcreteDependency

java.lang.Object

edu.stanford.nlp.trees.UnnamedDependency

edu.stanford.nlp.trees.UnnamedConcreteDependency

All Implemented Interfaces:

Dependency<Label,Label,Object>, Serializable

public class UnnamedConcreteDependency
extends UnnamedDependency

An individual dependency between a head and a dependent. The dependency is associated with the token indices of the lexical items.

A key difference between this class and UnnamedDependency is the equals() method. Equality of two UnnamedConcreteDependency objects is defined solely with respect to the indices. The surface forms are not considered. This permits a use case in which dependencies in two different parse trees have slightly different pre-processing, possibly due to pre-processing.
