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 Segment s produced by a Transducer . 
GammaAverageConfidenceEstimator 
Calculates the confidence in an extracted segment by taking the
average of P(s_io) for each state in the segment. 
GammaProductConfidenceEstimator 
Calculates the confidence in an extracted segment by taking the
product of eP(s_io) for each state in the segment. 
InstanceWithConfidence 
Helper class to store confidence of an Instance. 
IsolatedSegmentTransducerCorrector 
Corrects a subset of the Segment s 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 01 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.
