| 摘 要： | 针对运行在电子商务等交互式应用领域中的案例推理系统时,其案例库的规模很容易达到成千上万条且不能削减的特点,提出同时从两方面着手完成案例库维护:一方面用覆盖算法将案例库划分成覆盖领域,实现案例的选择性过滤使用;另一方面应用多层前馈神经网络改进案例匹配,提高检索效率.实验表明,该方法可以用来处理海量的高维数据,保证了系统的可用性. |
| 关 键 词： | 案例库维护 非精简案例库 选择性过滤 多层前馈神经网络 覆盖算法 |

| Abstract: | Case-based reasoning(CBR) systems running in interactive domains like E-commerce,easily accumulate thousands of cases that are not reducible and thus presenting a problem to the efficiency of retrieval.To solve this problem,a new method was proposed to achieve case-base maintenance(CBM)from both sides: one was employing the alternative-covering algorithm to partition the case library to many covering domains,thus realizing selective filtering;the other was using multi-layer feedforward neural networks(MFNN) to deal with case retrieval within the large-scale case library.Experimental results indicate that the proposed method is especially feasible for processing vast and high dimensional data,which can effectively guarantee the system's usability and enhance its capability. |
| Keywords: | CBM irreducible case library selective filter MFNN covering algorithm |
