Regular matching and inclusion on compressed tree patterns with constrained context variables
AbstractWe study the complexity of regular matching and inclusion for compressed tree patterns with context variables subject to regular constraints. Context variables with regular constraints permit to properly generalize on unranked tree ...

A central tendency-based privacy preserving model for sensitive XML association rules using Bayesian networks
Intelligent Data Analysis (INDA), Volume 18, Issue 2Pages 281–303The rationale of XML design is to transfer and store data at different levels. A key feature of these levels in an XML document is to identify its components for additional processing. XML components can expose sensitive information after application of ...

Fuzzy XML and prioritized fuzzy XQuery with implementation
Journal of Intelligent & Fuzzy Systems: Applications in Engineering and Technology (JIFS), Volume 26, Issue 1Pages 303–316In real life, as opposed to virtual, most information comes in the form of imprecise or incomplete values. XML technology has made great progress in the field of storage and data transfer. We developed XML extension which combines indefiniteness in the ...

Queries on Xml streams with bounded delay and concurrency
Information and Computation (ICOM), Volume 209, Issue 3Pages 409–442https://doi.org/10.1016/j.ic.2010.08.003Query answering algorithms on Xml streams check answer candidates on the fly in order to avoid the unnecessary buffering whenever possible. The delay and concurrency of a query are two measures for the degree of their streamability. They count the ...
