LBJ2.classify
Class MultiValueComparer

java.lang.Object
  LBJ2.classify.Classifier
      LBJ2.classify.ValueComparer
          LBJ2.classify.MultiValueComparer

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class MultiValueComparer
extends ValueComparer

This classifier applies another classifier to the example object and returns a Boolean feature (with value "true" or "false") indicating whether a given feature value appeared in the output of the classifier. This behavior differs from that of ValueComparer because it does not assume that the given classifier will return only a single feature.

Method Detail

classify

public FeatureVector classify(java.lang.Object o)

Returns a Boolean feature (with value "true" or "false") indicating whether the output of ValueComparer.labeler applied to the argument object contained the feature value referenced by ValueComparer.value.

Overrides:

classify in class ValueComparer

Parameters:

o - The object to make decisions about.

Returns:

A feature vector containing the feature described above.

toString

public java.lang.String toString()

The String representation of a ValueComparer has the form "ValueComparer(child), where child is the String representation of the classifier whose value is being compared.

Overrides:

toString in class ValueComparer

Returns:

A string of the form described above.
