Оптимизация вычисления обратных осей языка XML Path при его реализации функциональными методами.

open access: yesТруды Института системного программирования РАН, 2004
XPath – это язык для адресации структурных частей XML-документа. Функциональный язык программирования Scheme позволяет естественным образом представлять и обрабатывать XML-документы в виде SXML и обеспечивает единую среду для реализации XML-приложений.

Executable First-Order Queries in the Logic of Information Flows [PDF]

open access: yesLogical Methods in Computer Science
The logic of information flows (LIF) has recently been proposed as a general framework in the field of knowledge representation. In this framework, tasks of procedural nature can still be modeled in a declarative, logic-based fashion.

Twig Query Optimization Based on Partial Evaluation [PDF]

open access: yesJisuanji gongcheng, 2016
TreeMatch algorithm is widely considered to be an effective Twig query algorithm.According to the disadvantage of TreeMatch algorithm’s repeated analysis on Twig pattern,partial evaluation technology in the field of compilation is applied,and a Twig ...

Pathfinder: XQuery - The Relational Way [PDF]

open access: yes, 2005
Relational query processors are probably the best understood (as well as the best engineered) query engines available today. Although carefully tuned to process instances of the relational model (tables of tuples), these processors can also provide a ...

Datacubes as enabler for advanced decision support systems in land management

open access: yesLand Degradation &Development, Volume 35, Issue 11, Page 3579-3592, 15 July 2024.
Abstract Informed, wise, land management has been a challenge since a long time, but has gained extra importance through the need for responding to climate change effects. The European Green Deal is one example of a concertation effort in a world where data availability, sharing options, and just‐in‐time exploitation are not entirely solved.

Complete Subhedge Projection for Stepwise Hedge Automata

open access: yesAlgorithms
We demonstrate how to evaluate stepwise hedge automata (Shas) with subhedge projection while completely projecting irrelevant subhedges. Since this requires passing finite state information top-down, we introduce the notion of downward stepwise hedge ...

TypEx : a type based approach to XML stream querying [PDF]

open access: yes, 2003
We consider the topic of query evaluation over semistructured information streams, and XML data streams in particular. Streaming evaluation methods are necessarily eventdriven, which is in tension with high-level query models; in general, the more ...

Logics for Unranked Trees: An Overview [PDF]

open access: yes, 2005
Labeled unranked trees are used as a model of XML documents, and logical languages for them have been studied actively over the past several years. Such logics have different purposes: some are better suited for extracting data, some for expressing ...

Satisfiability of XPath Expressions [PDF]

open access: yes, 2004
In this paper, we investigate the complexity of deciding the satisfiability of XPath 2.0 expressions, i.e., whether there is an XML document for which their result is nonempty. Several fragments that allow certain types of expressions are classified as either in PTIME or NP-hard to see which type of expression make this a hard problem.

An empirical study to compare three web test automation approaches: NLP‐based, programmable, and capture&replay

open access: yesJournal of Software: Evolution and Process, Volume 36, Issue 5, May 2024.
A new advancement in test automation is the use of natural language processing (NLP) to generate test cases from natural language text. NLP is innovative in this context and promises of reducing test cases creation time and simplifying understanding. This paper investigates the adoption of NLP‐based test automation in the web context with a series of ...
