Method Detail

getLL

public BigDecimal getLL()

Get the Log-Likelihood of all the examples/queries.

Overrides:

getLL in class AbstractEDGE

Returns:

the log-likelihood of all the examples/queries

getTimeMap

public Map<String,Long> getTimeMap()

Description copied from class: AbstractParameterLearningAlgorithm

Gets the map of the time in milliseconds spent by various algorithms.

Overrides:

getTimeMap in class AbstractEDGE

Returns:

init

public void init()
          throws ComponentInitException

Description copied from interface: Component

Method to be called after the component has been configured. Implementation of components can overwrite this method to perform setup and initialisation tasks for this component.

Specified by:

init in interface Component

Overrides:

init in class AbstractEDGE

Throws:

ComponentInitException - This exception is thrown if any exceptions occur within the initialisation process of this component. As component developer, you are encouraged to re-throw occurring exception as ComponentInitException and giving an error message as well as the actually exception by using the constructor ComponentInitException(String, Throwable).

getParameter

public BigDecimal getParameter(org.semanticweb.owlapi.model.OWLAxiom ax)
                        throws ParameterLearningException

Description copied from class: AbstractParameterLearningAlgorithm

Gets the probabilistic parameter of an axiom

Overrides:

getParameter in class AbstractEDGE

Returns:

the probabilistic parameter of the axiom

Throws:

ParameterLearningException

getLearnedOntology

public org.semanticweb.owlapi.model.OWLOntology getLearnedOntology()

Overrides:

getLearnedOntology in class AbstractEDGE

changeSourcesOntology

public void changeSourcesOntology(org.semanticweb.owlapi.model.OWLOntology ontology)

Overrides:

changeSourcesOntology in class AbstractEDGE

reset

public void reset()

Overrides:

reset in class AbstractEDGE

getLOGZERO

public BigDecimal getLOGZERO()

Overrides:

getLOGZERO in class AbstractEDGE

start

public void start()

Description copied from interface: LearningAlgorithm

Starts the algorithm. It runs until paused, stopped, or a termination criterion has been reached.
