摘要:... As a mainstream XML query language, XQuery is the core of XML processing. It is critical to take full advantage of multi-core computing to improve XML processing performance through parallelization of XQuery. However, usually it is difficult to parallelize XQuery programs bec...

摘要:... In this paper an XQuery property‐based testing tool is presented, which enables to automatically test XQuery programs. The tool is able to systematically generate XML instances (i.e., test cases) from a given XML schema, and to filter XML instances with input properties sp...

摘要:Abstract(#br)This paper presents an extensive and detailed experimental evaluation of XQuery processors. The study consists of running five publicly available XQuery benchmarks—the Michigan benchmark (MBench), XBench, XMach-1, XMark and X007—on six XQuery processors, three s...

摘要:Abstract(#br)XQuery, the defacto XML query language, is a functional language with operational semantics, which precludes the direct application of classical query optimization techniques. The features of XQuery, such as nested expressions and ordered semantics, further aggravate...

摘要:Abstract(#br)XSLT and XQuery are the languages developed by the W3C for transforming and querying XML data. XSLT and XQuery have the same expressive power and can be indeed translated into each other. Many tools either support XSLT or XQuery. In this paper, we show how to transla...

摘要:Abstract(#br)A substantial part of the database research field focusses on optimizing XQuery evaluation. However, there is a lack of tools allowing to easily compare different implementations of isolated language features. This implies that there is no overview of which engines p...

摘要:Abstract(#br)This paper presents a survey and an analysis of the XQuery benchmark publicly available in 2006—XMach-1, XMark, X007, the Michigan benchmark, and XBench—from different perspectives. We address three simple questions about these benchmarks: How are they used?...

摘要:... We propose the fuzzy XQuery processing techniques for Native XML database systems, wherethe weights of attributes can be described by linguistic terms represented by fuzzy numbers. The proposedfuzzy XQuery processing techniques allow the users to use linguistic terms in the ...

摘要:... However, users may have only a limited knowledge of the XML structure, and may be unable to produce a correct XQuery expression, especially in the context of a heterogeneous information collection. The default is to use keyword-based search and we are all too familiar wi...

摘要:Abstract(#br)To improve the query performance over XML documents in a distributed environment, we develop a semantic caching system named ACE-XQ for XQuery queries. ACE-XQ applies innovative query containment and rewriting techniques to answer user queries using cached queries. W...
