Efficient Evaluation of Multiple Queries on Streamed XML Fragments [chapter]

Huan Huo, Rui Zhou, Guoren Wang, Xiaoyun Hui, Chuan Xiao, Yongqian Yu
2006 Lecture Notes in Computer Science  
Based on tid+ tree, it then proposes a notion of FQ-Index as the core in M-XFPro to index both multiple queries and XML fragments for processing multiple XPath queries involving simple path and twig path  ...  By taking advantage of schema information for XML, this paper proposes a model of tid+ tree to construct multiple queries over XML fragments and to prune off duplicate and dependent operations.  ...  In this paper, we present an efficient framework and a set of techniques for processing multiple XPath queries over streamed XML fragments.  ...

Efficient Fragmentation of Large XML Documents [chapter]

Angela Bonifati, Alfredo Cuzzocrea
Lecture Notes in Computer Science  
This allows us to predict bounding intervals of structural properties of output (XML) fragments for efficient query processing of distributed XML data.  ...  Fragmentation techniques for XML data are gaining momentum within both distributed and centralized XML query engines and pose novel and unrecognized challenges to the community.  ...  XFrag [4] is a framework for processing XQuery-formatted queries on XML fragments in order to reduce memory processing.  ...
