Class TreebankLinker

java.lang.Object

      opennlp.tools.coref.DefaultLinker
          opennlp.tools.lang.english.TreebankLinker

All Implemented Interfaces:

Linker

public class TreebankLinker
extends DefaultLinker

This class perform coreference for treebank style parses. It will only perform coreference over constituents defined in the trees and will not generate new constituents for pre-nominal entities or sub-entities in simple coordinated noun phrases. This linker requires that named-entity information also be provided. This information can be added to the parse using the -parse option with EnglishNameFinder.
