基于差异特征的案例可拓修改方法研究与应用
Research and application of case extension revision method based on character difference
摘要
Abstract
Case revision, as a crucial and difficult step in case-based reasoning technology, exists defects on the hard acquisition of revision knowledge and poor generality for modifying method. Aiming at these problems, in the paper, the extension theory is combined. On the basis of unified and deep case description and similarity retrieve by the basic-element models, the satisfaction evaluation is made for the similar cases. Then, for the evaluated incompatible similar cases, a case-replacement extension repair approach is proposed based on the character difference. Finally, an assessment is applied to determine the best solution from the modified cases. Therefore, a complete case extension revision strategy is formed. The determination of the number for the theoretical plate in the distillation columns is taken as an example for the verification of the proposed strategy. The application result indicates that the strategy has a lower dependence on knowledge and stronger learning ability, which provides a new idea for the further study on the case revision technology.关键词
