Since the boom in new proposals on techniques for efficient querying of XML data is now
over and the research world has shifted its attention toward new types of data formats, we …

With XML becoming a ubiquitous language for data interoperability purposes in various
domains, efficiently querying XML data is a critical issue. This has lead to the design of …

In XML search systems twig queries specify predicates on node values and on the structural
relationships between nodes, and a key operation is to join individual query node matches …

With the advent of IoT, storing, indexing and querying XML data efficiently is critical. To
minimize the cost of querying XML data, researchers have proposed many indexing …

Searching for occurrences of a twig pattern query (TPQ) in an XML document is a core task
of all XML database query languages. The generalized twig pattern (GTP) extends the TPQ …

In recent years, many approaches to XML twig pattern searching have been developed.
Holistic approaches such as TwigStack are particularly significant in that they provide a …

An evaluation of XML queries such as XQuery or XPath expressions represents a
challenging task due to its complexity. Many algorithms have been introduced to cope with …

In recent years, many approaches to XML twig pattern searching have been developed.
Holistic approaches are particularly significant in that they provide a theoretical model for …

The F&B-index is used to speed up pattern matching in tree and graph data, and is based on
the maximum F&B-bisimulation, which can be computed in loglinear time for graphs. It has …

Twig joins are key building blocks in current XML indexing systems, and numerous
algorithms and useful data structures have been introduced. We give a structured …
