The problem of answering XML queries using path-based indexes is to find efficient
methods for accelerating the XML query with pre-designed index structures over the XML …

Due to its flexibility, XML is becoming the de facto standard for exchanging and querying
documents over the Web. Many XML query languages such as XQuery and XPath use label …

The emergence of the Web has increased interests in XML data. XML query languages such
as XQuery and XPath use label paths to traverse the irregularly structured data. Without a …

Various index structures have been proposed to speed up the evaluation of XML path
expressions. However, existing XML path indices suffer from at least one of three limitations …

As many metadata are encoded in XML, and many digital libraries need to manage XML
documents, efficient techniques for searching in such formatted data are required. In order to …

With the advent of XML as a standard for data representation and exchange on the Internet,
storing and querying XML data becomes more and more important. Several XML query …

XML is an emerging standard for data representation and exchange on the Web. XML is
represented as a tree and the query as a regular path expression (RPE). The query is …

A number of indexing techniques have been proposed in recent times for optimizing the
queries on XML and other semi-structured data models. Most of the semi-structured models …

Finding the occurrences of structural patterns in XML data is a key operation in XML query
processing. Existing algorithms for this operation focus almost exclusively on path-patterns …

XML's increasing diffusion makes efficient XML query processing and indexing all the more
critical. Given the semistructured nature of XML documents, however, general query …
