Interface Summary

TransducerCorrector

Interface for transducerCorrectors, which correct a subset of the Segments produced by a Transducer.

Class Summary

ConfidenceCorrectorEvaluator	Calculates the effectiveness of "constrained viterbi" in propagating corrections in one segment of a sequence to other segments.
ConfidenceEvaluator
ConfidenceEvaluator.EntityConfidence	a simple class to store a confidence score and whether or not this labeling is correct
ConstrainedForwardBackwardConfidenceEstimator	Estimates the confidence of a Segment extracted by a Transducer by performing a "constrained lattice" calculation.
ConstrainedViterbiTransducerCorrector	Corrects a subset of the Segments produced by a Transducer.
GammaAverageConfidenceEstimator	Calculates the confidence in an extracted segment by taking the average of P(s_i|o) for each state in the segment.
GammaProductConfidenceEstimator	Calculates the confidence in an extracted segment by taking the product of eP(s_i|o) for each state in the segment.
InstanceWithConfidence	Helper class to store confidence of an Instance.
IsolatedSegmentTransducerCorrector	Corrects a subset of the Segments produced by a Transducer.
MaxEntConfidenceEstimator	Estimates the confidence of a Segment extracted by a Transducer using a MaxEnt classifier to classify segments as "correct" or "incorrect." xxx needs some interface work
MaxEntSequenceConfidenceEstimator	Estimates the confidence of a Sequence extracted by a Transducer using a MaxEnt classifier to classify Sequences as "correct" or "incorrect." xxx needs some interface work.
MinSegmentConfidenceEstimator	Estimates the confidence of an entire sequence by the least confidence segment.
NBestViterbiConfidenceEstimator	Estimates the confidence of an entire sequence by the probability that one of the the Viterbi paths rank 2->N is correct.
PipedInstanceWithConfidence	Helper class to store confidence of an Instance.
QBCSequenceConfidenceEstimator	Estimates the confidence of an entire sequence by the "disagreement" among a committee of CRFs.
RandomConfidenceEstimator	Randomly assigns values between 0-1 to the confidence of a Segment.
RandomSequenceConfidenceEstimator	Estimates the confidence of an entire sequence randomly.
SegmentProductConfidenceEstimator	Estimates the confidence of an entire sequence by combining the output of a segment confidence estimator for each segment.
SequenceConfidenceInstance	Stores a Sequence and a PropertyList, used when extracting features from a Sequence in a pipe for confidence prediction
TransducerConfidenceEstimator	Abstract class that estimates the confidence of a Segment extracted by a Transducer.
TransducerSequenceConfidenceEstimator	Abstract class that estimates the confidence of a Sequence extracted by a Transducer.Note that this is different from TransducerConfidenceEstimator, which estimates the confidence for a single Segment.
ViterbiConfidenceEstimator	Estimates the confidence of an entire sequence by the probability of the Viterbi path normalized by the probabliity of the entire lattice.
ViterbiRatioConfidenceEstimator	Estimates the confidence of an entire sequence by the ration of the probabilities of the first and second best Viterbi paths.
