Class ConjunctionTransform

java.lang.Object

edu.ucla.sspace.dependency.ConjunctionTransform

All Implemented Interfaces:

DependencyTreeTransform

public class ConjunctionTransform
extends Object
implements DependencyTreeTransform

Transforms the dependency tree by adding conjunction relations between head words and a list of words joined by a conjunction. For example, consider the sentence "There are many types of mammals, such as cats, dogs, and dolphins." If "such as" is the dominate node over the list of animals, starting with "cats", and each animal node is connected to proceeding node with "conj" link, then this method will add a link from "such as" to each of the animal nodes. Essentially, this bubbles up the conjunction link so that elements in a list are directly connected to the head node.
