Path-Based Range Query Processing Using Sorted Path and Rectangle Intersection Approachof the query points in P was revisited. We further present two techniques for PRQ that improves the running time of the two pruning rules, called sorted path and rectangle intersection. Empirical results from real life datasets supported our theoretic results that PRQ using sorted path is better than the other approaches.

A Lightweight XML Repository Supporting Dynamic Partial Update of XML Datasenders to the receiving devices. The proposed XML repository for the receiving devices deals with the XML data in such a way that the XML fragments can be efficiently reconstructed, searched and retrieved, while dynamic updates and versioning of the XML fragments are supported with marginal costs.

UB-Tree Based Efficient Predicate Index with Dimension Transform for Pub/Sub System feasibility of the proposed index is evaluated in simulated publish/subscription environment. Results show that in almost all the cases, the performance our proposed index is 4 order of magnitude faster than counting algorithm. Because our index can support both equality operator (=) and non-equali

Emergent Semantics Principles and Issuesand partially connected central servers rose an intricate web of millions of information sources loosely connecting one to another. Today, we expect to witness the extension of this revolution with the wide adoption of meta-data standards like RDF or OWL underpinning the creation of a semantic web.

SF-Tree: An Efficient and Flexible Structure for Estimating Selectivity of Simple Path Expressions w. structure to store a summary of the path expressions that are present in an XML document collection. In this paper we propose a new structure called .to address the selectivity estimation problem. SF-Tree provides a flexible way for the users to choose among accuracy, space requirement and selecti
