A fuzzy match groups rows that have approximately the same values. 模糊匹配对具有相似值的行进行分组。
Based on a fuzzy matching model and a fuzzy evaluating model, a multi-layer model is provided for quantitative discription of the similarity at different layers. 该策略在模糊匹配模型和模糊评价模型基础上,通过建立多层次评价模型,定量描述实例在不同层次的相似性,综合评价选出最适当的实例。
