Interface Summary

Interface	Description
ActiveLearningAlgorithm	Active Learning algorithms are those, which can use feedback from an oracle.
AxiomLearningAlgorithm<T extends org.semanticweb.owlapi.model.OWLAxiom>
AxiomLearningProgressMonitor	The AxiomLearningProgressMonitor interface should be implemented by objects that wish to monitor the progress of an axiom learning algorithm.
AxiomScoreCalculator
BaseReasoner	Contains the following reasoning/query operations: queries for elements contained in the knowledge base (classes, properties, ...) basic reasoning requests related to the knowledge base as a whole (e.g.
ClassExpressionLearningAlgorithm	Basic interface for algorithms learning OWL/DL class expressions.
Component	Base interface of all components.
FuzzyClassExpressionLearningAlgorithm	Basic interface for algorithms learning fuzzy OWL/DL class expressions.
Heuristic
IndividualReasoner	Reasoning requests/queries related to individuals in the knowledge base.
KnowledgeSource	Basic interface for all DL-Learner knowledge sources.
LearningAlgorithm	Basic interface for all DL-Learner learning algorithms.
LearningProblem	Basic interface for all DL-Learner learning problems.
Oracle	An oracle can be used by a learning algorithm to interactively ask for the classification of an individual.
Reasoner	List of available reasoning/query methods.
ReasonerComponent	Base class of reasoner all components.
ResumableLearningAlgorithm	Interface for learning algorithms, which can be paused and later continued.
SchemaReasoner	Reasoning requests related to the schema of the knowledge base.
SparqlQueryLearningAlgorithm	Basic interface for algorithms learning SPARQL queries.
StoppableLearningAlgorithm	Interface for algorithms, which can be stopped and checked whether they are running.
