Class SurfacePattern

java.lang.Object

edu.stanford.nlp.patterns.surface.SurfacePattern

All Implemented Interfaces:

Serializable, Comparable<SurfacePattern>

public class SurfacePattern
extends Object
implements Serializable, Comparable<SurfacePattern>

To represent a surface pattern in more detail than TokenSequencePattern (this class object is eventually compiled as TokenSequencePattern via the toString method). See PatternToken for more info on how matching of target phrases is done. Author: Sonal Gupta (sonalg@stanford.edu)
