Approximate XQuery Reformulation Based on GLAV Mapping and Unification
The mediation is based on an essential component called mediator. The main role of the mediator is to reformulate a user query, written in terms of global schema, in queries written in terms of sources schemas. This paper describes an algorithm for reformulation of XQuery queries. The algorithm is based on the principle of logical equivalence, simple and complex unification, to obtain a better ...

This paper describes an algorithm for reformulation of XQuery queries. The mediation is based on an essential component called mediator. The main role of the mediator is to reformulate a user query, written in terms of global schema, in queries written in terms of sources schemas. Our algorithm is based on the principle of logical equivalence, simple and complex unification, to obtain a better ...
متن کاملReformulating Aggregate Queries Using Views
We propose an algorithm to reformulate aggregate queries using views in a data integration LAV setting. Our algorithm considers a special case of reformulations where aggregates in the query are expressed as views over aggregates in the view definitions. Although the problem of determining whether two queries are equivalent is undecidable, our algorithm returns an equivalent reformulation if on...
متن کاملReformulating Queries: Theory and Practice
We consider a setting where a user wants to pose a query against a dataset where background knowledge, expressed as logical sentences, is available, but only a subset of the information can be used to answer the query. We thus want to reformulate the user query against the subvocabulary, arriving at a query equivalent to the user’s query assuming the background theory, but using only the restri...
متن کاملReformulating XPath queries and XSLT queries on XSLT views
Applications using XML for data representation very often use different XML formats and thus require the transformation of XML data. The common approach transforms entire XML documents from one format into another, e.g. by using an XSLT stylesheet. Different from this approach, we use an XSLT stylesheet in order to transform a given XPath query or a given XSLT query so that we retrieve and tran...
