Optimal nonrecursive datalog rewritings of linear TGDs and bounded (Hyper)Tree-width queries
P. 1–12.
Bienvenu M., Kikot S., Kontchakov R., Ryzhikov V., Zakharyaschev M.
Our concern is answering ontology-mediated queries (Ο q), whereΟ is a set of linear tgds and q a conjunctive query (CQ) of bounded hypertree width. Assuming that the arity of predicates is bounded, we show that polynomial-size nonrecursive Datalog rewritings can be constructed and executed in (i) LOGCFL for OMQs with ontologies of bounded existential depth; (ii) NL for OMQs with ontologies of bounded depth and CQs whose hypertree decompositions have a bounded number of leaves; (iii) LOGCFL for OMQs with acyclic CQs whose join trees have a bounded number of leaves.

Most of scientific research involves the use of computational tools, while researchers have low IT competences. The efficiency of working with computational modules for scientific research can be significantly increased by guaranteeing reproducibility, interactivity, and reusability of producing artifacts. This can be achieved by using a reactive environment with a standardized set of UI controls, ...

Integrating an Ontology-Driven Approach to Data Visualization and AI Based Visualization with Plotly
A.D. Dzheiranian, L.N. Lyadova, Proceedings of the Institute for System Programming of the RAS 2025 Vol. 37 No. 4 P. 191–206
This study introduces an AI-driven assistant prototype that automates the generation of data visualization scripts from natural language queries, eliminating the need for users to have programming skills. The article examines research aimed at developing tools for effective data visualization, compares data visualization systems based on the use of artificial intelligence, and shows the limitations ...

From its very beginning, the field of game studies is haunted by the question of video game ontology: what is a game and what are its fundamental components? Numerous authors, such as Ian Bogost and Alex Gekker, have written on the impossibility of establishing an exhaustive ontology of games. At the same time, game design ...

Несмотря на широкую полемику о тех или иных интеллектуальных результатах проекта И. Канта в посткантовской философии, значимость «коперниканского переворота», осуществленного в «Критике чистого разума», очевидна. Ни три проекта позитивизма (которые необходимо отличать от идей эпигонов физикализма), ни феноменология и герменевтика, ни аналитическая философия не смеют претендовать на непосредственное познание мира самого по себе, а если ...

This paper deals with L. Wittgenstein's philosophy of language. Author examines the legitimacy of Wittgenstein‘s ideas for contemporary pragmatism and references for his philosophy in H. Putnam's late works. The seeming contradictions between the theories of two philosophers are demonstrated. Nevertheless, it is argued that Wittgenstein's epistemology and ontology has intellectual relevance for Putnam's project. ...

We present a computational model for Parsing Expression Grammars (PEGs). The predecessor of PEGs top-down parsing languages (TDPLs) were discovered by A. Birman and J. Ullman in the 1960-s, B. Ford showed in 2004 that both formalisms recognize the same class named Parsing Expression Languages (PELs). A. Birman and J. Ullman established such important properties ...

Existential threat is often mentioned in political rhetoric. While it is mostly used to denote threats to humanity as a whole, like climate change or AI, it is also used on a smaller scale. Existential threat to a state or a similar entity is often evoked too. Such a threat is considered grave enough to ...

The article is about the discussion between realists and illusionists on phenomenal consciousness, phenomenal properties or qualia. The author considers what he calls epistemological-ontological transition made by illusionists and realists – transition from epistemologically significant statements to ontologically significant ones. The option to avoid such transition is tested in order to overcome some obstacles that ...

Forest is a multi-layered canopy, where overstory and understory implement different biogeochemical cycles, phenology and functional role. Remote sensing products typically estimate forest total Leaf Area Index (LAI), while few quantify its components. The theoretical understanding of foliage distribution between layers is still quite limited. In this study we’ve developed a semi-empirical model for decomposition ...
