1) path frequency tree
路径频率树
1.
Based on the Hole-Filler model,a path frequency tree(PFT) is defined according to the statistic information on queries about XML to set out a sibling-based document fragmentation policy including corresponding algorithm.
在Hole-Filler模型的基础上,首先利用XML的查询统计信息,定义了路径频率树,提出了基于兄弟关系的XML流数据剪切分片策略及其算法。
