Rewriting XPath queries using materialized XPath views
Let XP(/, //, [ ]) be the fragment of XPath 1.0, consisting of queries that involve only the child and descendant axes, and predicates without disjunction or negation (and no wildcard nodetests); these queries can be represented as tree patterns. We consider the problem of rewriting a query Q using a materialized view V , where Q,V ∈ XP(/, //, [ ]). We present more efficient algorithms for the ...
متن کاملFiltering Unsatisfiable XPATH Queries
The satisfiability test checks, whether or not the evaluation of a query returns the empty set for any input document, and can be used in query optimization for avoiding the submission and the computation of unsatisfiable queries. Thus, applying the satisfiability test before executing a query can save processing time and query costs. We focus on the satisfiability problem for queries formulate...

متن کاملEmbedding Xpath Queries into SPARQL Queries
While XPath is an established query language developed by the W3C for XML, SPARQL is a new query language developed by the W3C for RDF data. Comparisons between the data models of XML and RDF and between the query languages XPath and SPARQL are missing. Since XML and XPath are earlier recommendations of the W3C than RDF and SPARQL, currently more XML data and XPath queries are used in applicati...
متن کاملFuzzy XPath Queries in XQuery
We have recently designed a fuzzy extension of the XPath language which provides ranked answers to flexible queries taking profit of fuzzy variants of and, or and avg operators for XPath conditions, as well as two structural constraints, called down and deep, for which a certain degree of relevance is associated. In this work, we describe how to implement the proposed fuzzy XPath with the XQuer...
