Production of alternative fuels from waste: assumptions for the design of new fuel recipes
International Journal of Sustainable Engineering, 2021 Alternative fuel (RDF) is known as stable and safe energy source for the cement and energy industries. In connection with the quality standards of the main recipients of RDF, there is a need for a comprehensive look at issues related to the production of

THE USE OF SPARQL LANGUAGE IN ONTOLOGICAL MODELING OF MULTI-AGENT SYSTEMS IN SEMANTIC WEB
Известия высших учебных заведений. Поволжский регион:Технические науки, 2020 Background. The widespread use of multi-agent systems conception and technologies of the semantic Web, as well as the beginning of their active joint use in the design and implementation of information systems, requires the development of new adequate

Formal Foundations for RDF/S KB Evolution [PDF]
, 2012 There are ongoing efforts to provide declarative formalisms of integrity constraints over RDF/S data. In this context, addressing the evolution of RDF/S knowledge bases while respecting associated constraints is a challenging issue, yet to receive a ...

Model Theory and Entailment Rules for RDF Containers, Collections and Reification [PDF]
, 2009 An RDF graph is, at its core, just a set of statements consisting of subjects, predicates and objects. Nevertheless, since its inception practitioners have asked for richer data structures such as containers (for open lists, sets and bags), collections

Extended RDF: Computability and Complexity Issues [PDF]
, 2015 ERDF stable model semantics is a recently proposed semantics for ERDF ontologies and a faithful extension of RDFS semantics on RDF graphs. In this paper, we elaborate on the computability and complexity issues of the ERDF stable model semantics. Based
