Reasoning with organizational case bases in the absence of negative exemplars
13 Jun 2013
Abstract
Organizational case bases are gathered based on the organization they serve; cases are not selected taking reasoning into account. Thus, organizational case bases may lack negative exemplars and have multiple solutions to one problem, making it difficult learn weights for reasoning. Case bases in typical Process-Oriented Case-Based Reasoning (POCBR) contexts are organizational, thus inheriting those problems. This paper describes an approach to identify a subset of cases from an organizational case base that meets the criterion that similar problems have similar solutions. This subset is then used to characterize classes, establishing positive and negative exemplars that are then used to learn weights for reasoning with the entire case base. We apply this approach to three organizational case bases, showing significant improvements in accuracy with weights learned with this approach in case bases without negative exemplars.
