Creates a new instance of RandomConversationBlockSelector

Method Detail

getNextFeatureKeyImpl

protected FeatureKey getNextFeatureKeyImpl(Problem problemSoFar,
                                           RetrievalResults casesUnderConsideration,
                                           CCBRDomain domain)

Specified by:

getNextFeatureKeyImpl in class AbstractConversationBlockSelector

reset

public void reset()

Reset the state of the conversation block selector, to prepare for a new conversation. For some conversation block selectors, this may be a dummy operation.

Specified by:

reset in interface ConversationBlockSelector

initConversationImpl

protected void initConversationImpl(Problem initialProblem)

Specified by:

initConversationImpl in class AbstractConversationBlockSelector

toSwing

public javax.swing.JComponent toSwing(Domain domain)

Specified by:

toSwing in interface SwingRepresentableWithDomain

toSwing

public javax.swing.JComponent toSwing(int detailLevel)

Detail level may be ignored by implementations. If used, the standard is for detailLevel 0 to be least detail, with higher values growing more detailed. 0 is least detail, higher numbers are more

Specified by:

toSwing in interface SwingRepresentable

makeSuggestions

public SuggestionSet makeSuggestions(java.lang.Object[] args,
                                     double totalStrength)

By default, a conversation block selector as an ensemble member gives all its strength to its single greatest suggestion.

Specified by:

makeSuggestions in interface EnsembleMember

Parameters:

args - The arguments take the following form:
args[0] is Problem problemSoFar
args[1] is RetrievalResults casesUnderConsideration
args[2] is CCBRDomain domain

totalStrength - The total amount of strength that this ensemble member may divide among its suggestions. The simplest case has each ensemble member with totalStrength = 1.0, giving all its strength to its single strongest suggestion.

decisionMade

public void decisionMade(java.lang.Object decision)

The decision indicates the key chosen by the ensemble, so don't consider that key again.

Specified by:

decisionMade in interface EnsembleMember
