Traditional grouping method could not use all attributes of entity and fuzzy correlation space based approach needed more match computation . fuzzy grouping method added two new techniques based on the fuzzy correlation space approach : fuzzy consistent relation based weight distribution and grid based preprocessing 由于传统的分组方法不能充分利用实体所有的属性，而基于模糊关联空间的分组方法需要过多的运算量，本文提出一种模糊分组方法，该分组方法在基于模糊关联空间方法的基础上加入基于模糊一致性的权值分配方法和基于格子的预处理分组方法。
