Class ComponentCombo

java.lang.Object
  org.dllearner.utilities.components.ComponentCombo

public class ComponentCombo
extends Object

A mix of components, which are typically combined to create a full learning task. Add more constructors if you like (they should be useful in general, not just for a very specific scenario).

Constructor Detail

ComponentCombo

public ComponentCombo(AbstractKnowledgeSource source,
                      AbstractReasonerComponent reasoner,
                      AbstractLearningProblem problem,
                      AbstractCELA algorithm)

Builds a component combination object from the specified components.

Parameters:

source - A knowledge source.

reasoner - A reasoner.

problem - A learning problem.

algorithm - A learning algorithm.

ComponentCombo

public ComponentCombo(Set<AbstractKnowledgeSource> sources,
                      AbstractReasonerComponent reasoner,
                      AbstractLearningProblem problem,
                      AbstractCELA algorithm)

Builds a component combination object from the specified components.

Parameters:

sources - A set of knowledge sources.

reasoner - A reasoner.

problem - A learning problem.

algorithm - A learning algorithm.

ComponentCombo

public ComponentCombo(URL owlFile,
                      Set<String> posExamples,
                      Set<String> negExamples)

Builds a standard combination of components. Currently, this is an OWL File, the FastInstanceChecker reasoning algorithm, a definition learning problem with positive and negative examples, and the example based refinement algorithm.

Parameters:

owlFile - URL of an OWL file (background knowledge).

posExamples - Set of positive examples.

negExamples - Set of negative examples.

Method Detail

initAll

public void initAll()
             throws ComponentInitException
