public abstract class AbstractHeuristic
extends AbstractComponent
implements Heuristic<OENode>

Search algorithm heuristic for the ontology engineering algorithm. The heuristic has a strong bias towards short descriptions (i.e. the algorithm is likely to be less suitable for learning complex descriptions).

Method Detail

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

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).

compare

public int compare(OENode node1,
                   OENode node2)

Specified by:

compare in interface Comparator<OENode>

getNodeScore

public abstract double getNodeScore(OENode node)

Specified by:

getNodeScore in interface Heuristic<OENode>
