A tag-based document fragmentation algorithm built on DOM-based algorithm was then proposed to determine document filler points by fragmenting tag structure,so as to reduce the comparisons between element fan-outs and threshold.

• 然后；在此基础上；对标签结构进行剪切以确定文档的剪切点；提出了基于标签的XML流数据剪切分片算法；有效地减少了节点扇出度与阈值的比较次数.
