Classes in opennlp.maxent used by opennlp.maxent

AbstractDataIndexer
Abstract class for collecting event and context counts used in training.

Context
Class which associates a real valueed parameter or expected value with a particular contextual predicate or feature.

ContextGenerator
Generate contexts for maxent decisions.

DataIndexer
Object which compresses events in memory and performs feature selection.

DataStream
A interface for objects which can deliver a stream of training data to be supplied to an EventStream.

Evalable
Interface for components which use maximum entropy models and can evaluate the performace of the models using the TrainEval class.

EvalParameters
This class encapsulates the varibales used in producing probabilities from a model and facilitaes passing these variables to the eval method.

Event
The context of a decision point during training.

EventCollector
An interface for objects which read events during training.

EventStream
A object which can deliver a stream of training events for the GIS procedure (or others such as IIS if and when they are implemented).

FileEventStream
Class for using a file of events as an event stream.

GISModel
A maximum entropy model which has been trained using the Generalized Iterative Scaling procedure (implemented in GIS.java).

MaxentModel
Interface for maximum entropy models.

ModelDomain
A simple interface that represents a domain to which a particular maxent model is primarily applicable.

ModelSetter
A object to facilitate the resetting of a MaxentModel variable to a new value (model).

OnePassDataIndexer
An indexer for maxent model data which handles cutoffs for uncommon contextual predicates and provides a unique integer index for each of the predicates.

Prior
This interface allows one to implement a prior distribution for use in maximum entropy model training.

ComparablePredicate
A maxent predicate representation which we can use to sort based on the outcomes.

Context
Class which associates a real valueed parameter or expected value with a particular contextual predicate or feature.

GISModel
A maximum entropy model which has been trained using the Generalized Iterative Scaling procedure (implemented in GIS.java).
