Class KnowledgeManager

Object

kb.KnowledgeManager

public class KnowledgeManager
extends Object

Used for organizing the various sources of knowledge used by CharGer and Craft. A knowledge source is either a conceptual graph or a repertory grid. This class is generally reserved for high level methods dealing with the knowledge source management; most of the "lower level" detailed methods are found in ConceptManager.

Method Detail

performKnowledgeSummary

public void performKnowledgeSummary(JFrame owner)

Invokes Reporter's "displaySummary" for all the existing knowledge.

addKnowledgeSource

public void addKnowledgeSource(KnowledgeSource s)

Tells the Knowledge Manager that it's supposed to manage this particular knowledge source.

Parameters:

s - A knowledge source to be managed.

KnowledgeSource

forgetKnowledgeSource

public void forgetKnowledgeSource(KnowledgeSource s)

findTypeDescriptor

public AbstractTypeDescriptor[] findTypeDescriptor(String term,
                                                   boolean includeDuplicates)

Get all the type descriptors from any known knowledge sources that correspond to a term.

Parameters:

term - The term to look for.

includeDuplicates - Whether to include duplicates if they are found. A duplicate is defined to be any type descriptor that "equals" another one.

charger.obj.TypeDescriptor#equals

removeDuplicateDescriptors

public static AbstractTypeDescriptor[] removeDuplicateDescriptors(AbstractTypeDescriptor[] ts)

getAllGraphs

public Graph[] getAllGraphs()

getAllGrids

public TrackedRepertoryGrid[] getAllGrids()

findGraphsWithTypeHierarchy

public Graph[] findGraphsWithTypeHierarchy()

Locate any graphs that have type labels. Ideally there should be only one hierarchy, but I'd rather not get into the one-size-fits-all argument with the ontology group(s).

Returns:

a (possibly-empty) set of available knowledge source graphs that contain at least one type label.

createCurrentTupleMatcher

public AbstractTupleMatcher createCurrentTupleMatcher()

Uses Hub.matchingStrategy to determine which class to use for an instance of a tuple matcher. Any valid tuple matcher will work here, but usually the name is chosen from a list in the Preferences window. It's assumed that the matcher will be in the "kb" package, unless the name contains a period (".")
