public class Reasoner
extends Object

Reasoner provides a collection of static, utility methods to access a case base and perform reasoning tasks such as comparing a target case to source cases.

Constructor Summary

Reasoner()

Method Summary

static List<Case>	getCasesOverSimilarityThreshold(double threshold, Case targetCase, CaseBase caseBase) Retrieves the cases from the case base that are over (or equal to) a specified similarity threshold, when compared to the targetCase.
static Case	getMostSimilarCase(Case targetCase, CaseBase caseBase) Retrieves the case from the case base that most resembles the target case.
static List<Case>	getNMostSimilarCases(int n, Case targetCase, CaseBase caseBase) Given a novel scenario represented as a case find the N most similar cases in the caseBase provided.

Method Detail

getNMostSimilarCases

public static List<Case> getNMostSimilarCases(int n,
                                              Case targetCase,
                                              CaseBase caseBase)

Given a novel scenario represented as a case find the N most similar cases in the caseBase provided.

Parameters:

n - the number of similar cases to return

targetCase - the novel scenario

caseBase - the collection of cases to test against

Returns:

the n most similar cases as a list

getMostSimilarCase

public static Case getMostSimilarCase(Case targetCase,
                                      CaseBase caseBase)

Retrieves the case from the case base that most resembles the target case.

Parameters:

targetCase - the novel case

caseBase - the source cases

Returns:

the most similar source case

getCasesOverSimilarityThreshold

public static List<Case> getCasesOverSimilarityThreshold(double threshold,
                                                         Case targetCase,
                                                         CaseBase caseBase)

Retrieves the cases from the case base that are over (or equal to) a specified similarity threshold, when compared to the targetCase.

Parameters:

threshold - the similarity threshold

targetCase - the novel case

caseBase - the source cases

Returns:

the cases that are greater than or equal to the similarity threshold
