  edu.washington.cs.knowitall.extractor.conf.ReVerbOpenNlpClassifierTrainer

public class ReVerbOpenNlpClassifierTrainer
extends Object

Used to train the ReVerb confidence function using the features described by ReVerbFeatures. Given a set of LabeledBinaryExtraction instances, this class featurizes them and trains a logistic regression classifier using Weka's Logistic class. This class can be called from the command-line to train a classifier and save the resulting model to a file.
