Class EnglishHeadRules

java.lang.Object

eus.ixa.ixa.pipe.heads.EnglishHeadRules

All Implemented Interfaces:

opennlp.tools.parser.GapLabeler, opennlp.tools.parser.HeadRules

public class EnglishHeadRules
extends Object
implements opennlp.tools.parser.HeadRules, opennlp.tools.parser.GapLabeler

Class for storing the English head rules associated with parsing. The headrules are specified in $src/main/resources/en-head-rules NOTE: This is the very same class than the one inside opennlp.tools.parser.lang.en package. The main change is the return of the getHead() method: Every return constituents[i].getHead() has been replaced by the same return statement without the .getHead() method call. Other changes include removal of deprecated methods we do not need to use and adding some other methods for debugging.
