Path-based keyword search over XML streams
Recently, a great deal of attention has been focusing on processing keyword search over XML and XML streams. The keyword search is simple and provides a user-friendly way of retrieving required data from an XML data. Though its popularity, there is a concern over its efficiency. For this reason, several methods have been proposed to enable keyword search over XML streams. However, most of them ...

متن کاملEfficient XML Query Rewriting over the Multiple XML Views
{gaojun, dqyang, tjwang }@ pku.edu.cn Abstract XML query rewriting in the distributed computing environment receives high attention recently. Different from existing work, we focus on the query rewriting in the cases that there are multiple views at the client side. We design two data structures to manage the multiple XML views. MPTree is constructed from the main path of the XML views to gener...
متن کاملEfficient XML Keyword Search: From Graph Model to Tree Model
Keyword search, as opposed to traditional structured query, has been becoming more and more popular on querying XML data in recent years. XML documents usually contain some ID nodes and IDREF nodes to represent reference relationships among the data. An XML document with ID/IDREF is modeled as a graph by existing works, where the keyword query results are computed by graph traversal. As a compa...
متن کاملAn Efficient and Flexible Approach of Keyword Search in XML
In this chapter, firstly, the LCA-based approaches for XML keyword search are analyzed and compared with each other. Several fundamental flaws of LCA-based models are explored, of which, the most important one is that the search results are eternally determined nonadjustable. Then, the chapter presents a system of adaptive keyword search in XML, called AdaptiveXKS, which employs a novel and fle...
