摘　　要：案例库维护是基于案例推理系统的重要组成部分。针对此将查询性能预测思想应用于基于案例推理系统的案例库维护中,设计了案例增加策略及案例删除策略,分析了基于异构案例的组织方式,重点论述了案例检索日志的构建方法。实验结果表明,该方法能够使案例库维护具有较好的自适应性。Case-base maintenance is the core part of case-based reasoning systems.The paper applies the thought of query performance prediction in case-base maintenance based on case reasoning system,designs the increasing strategy and deleting strategy of case,analyzes the organization manner based on heterogeneous case,emphasizes on the building methods of case retrieval log.The experimental results prove that the method enables the maintenance of case base to have a good self-adaptability.
