基于序列的XML索引技术

Technologies of sequence-based XML indexing

对基于序列的XML索引技术进行了分析和研究,指出了由于同名兄弟节点的存在,导致了假警报,出现了查询不等价问题。并详细介绍了基于约束序列XML的索引技术,给出了基于序列的XML索引技术未来发展方向。

In this paper, the existing sequence-based method is reviewed and analyzed, and their main problem is query nonequivalence. For this purpose, a series of constraint methods and a constraint sequence matching algorithm that ensure the query equivalence is introduced. Some future directions on sequence-based XML indexing is prospected.
