Interface  Description 

Counter<E> 
An Object to double map used for keeping weights or counts for objects.

EquivalenceClasser<IN,OUT> 
A strategytype interface for specifying a function from
Object s
to their equivalence classes. 
ProbabilityDistribution<E> 
This is an interface for probability measures, which will allow
samples to be drawn and the probability of objects computed.

Sampler<T> 
An interace for drawing samples from the label
space of an object.

Scorer<L>  
TwoDimensionalCounterInterface<K1,K2> 
Interface representing a mapping between pairs of typed objects and double
values.

Class  Description 

AbstractCounter<E> 
Default implementations of all the convenience methods provided by
Counter . 
AccuracyStats<L> 
Utility class for aggregating counts of true positives, false positives, and
false negatives and computing precision/recall/F1 stats.

ClassicCounter<E> 
A specialized kind of hash table (or map) for storing numeric counts for
objects.

Counters 
Static methods for operating on a
Counter . 
Distribution<E> 
Immutable class for representing normalized, smoothed discrete distributions
from
Counters . 
GeneralizedCounter<K> 
A class for keeping double counts of
List s of a
prespecified length. 
IntCounter<E> 
A specialized kind of hash table (or map) for storing numeric counts for
objects.

MultiClassAccuracyStats<L>  
MultiClassChunkEvalStats 
Calculates phrase based precision and recall (similar to conlleval)
Handles various encodings such as IO, IOB, IOE, BILOU, SBEIO, []
Usage: java edu.stanford.nlp.stats.MultiClassChunkEvalStats [options] < filename
r  Do raw token based evaluation
d

MultiClassPrecisionRecallExtendedStats<L> 
Extension of MultiClassPrecisionRecallStats that also computes accuracy

MultiClassPrecisionRecallExtendedStats.MultiClassStringLabelStats  
MultiClassPrecisionRecallExtendedStats.StringStringConverter  
MultiClassPrecisionRecallStats<L>  
PrecisionRecallStats 
Utility class for aggregating counts of true positives, false positives, and
false negatives and computing precision/recall/F1 stats.
