Effective XQuery keyword using XML query processing

Effective keyword query structuring using NER for XML retrieval

Integrating Keyword Search into XML Query Processing

Due to the popularity of the XML data format, several query languages for XML have been proposed, specially devised to handle data whose structure is unknown, loose, or absent. While these languages are rich enough to allow for querying the content and structure of an XML document, a varying or unknown structure can make formulating queries a very difficult task. We propose an extension to XML ...

XQuery: An XML query language

The World Wide Web Consortium has convened a working group to design a query language for Extensible Markup Language (XML) data sources. This new query language, called XQuery, is still evolving and has been described in a series of drafts published by the working group. XQuery is a functional language comprised of several kinds of expressions that can be nested and composed with full generalit...

Processing XML Keyword Search by Constructing Effective Structured Queries

Recently, keyword search has attracted a great deal of attention in XML database. It is hard to directly improve the relevancy of XML keyword search because lots of keyword-matched nodes may not contribute to the results. To address this challenge, in this paper we design an adaptive XML keyword search approach, called XBridge, that can derive the semantics of a keyword query and generate a set...

Exploit keyword query semantics and structure of data for effective XML keyword search

Keyword search is a natural and user-friendly mechanism for querying XML data in information systems and Web based applications. One of the key tasks is to identify and return meaningful fragments as results, due to the limited expressiveness and the ambiguity of keyword queries. In this paper, we first studied query keyword patterns in order to exploit the user’s search intention behind the in...
