Class NumberOfIterationsConvergence

java.lang.Object
  edu.columbia.cs.cg.prdualrank.inference.convergence.impl.NumberOfIterationsConvergence

All Implemented Interfaces:

ConvergenceFinder

public class NumberOfIterationsConvergence
extends java.lang.Object
implements ConvergenceFinder

This class is used for our implementation of: "Searching Patterns for Relation Extraction over the Web: Rediscovering the Pattern-Relation Duality" . Y. Fang and K. C.-C. Chang. In WSDM, pages 825-834, 2011. For further information, WSDM 2011 Conference Website .

Description

Convergence method based on the number of iterations executed. After the object is asked N times for the method converged, it will return true, meaning that convergence has been reached.
For more information, please read the Algorithm PRDualRank(G,To) in Figure 6 of the mentioned paper.
