@KFStep(category="Tools", toolTipText="Label instances according to substring matches in String attributes") public class SubstringLabeler extends JPanel implements BeanCommon, Visible, Serializable, InstanceListener, TrainingSetListener, TestSetListener, DataSourceListener, EventConstraints, EnvironmentHandler, DataSource
A bean that finds matches in string attribute values (using either substring or regular expression matches) and labels the instance (sets the value of a new attribute) according to the supplied label for the matching rule. The new label attribute can be either multivalued nominal (if each match rule specified has an explicit label associated with it) or, binary numeric/nominal to indicate that one of the match rules has matched or not matched.
