Conjunctive Regular Path Queries under Injective Semantics [PDF]

open access: yes, 2023
We introduce injective semantics for Conjunctive Regular Path Queries (CRPQs), and study their fundamental properties. We identify two such semantics: atom-injective and query-injective semantics, both defined in terms of injective homomorphisms. These semantics are natural generalizations of the well-studied class of RPQs under simple-path semantics ...

Weakly Complete Semantics Based on Undecidedness Blocking [PDF]

open access: yesarXiv, 2021
In this paper we introduce a novel family of semantics called weakly complete semantics. Differently from Dung's complete semantics, weakly complete semantics employs a mechanism called undecidedness blocking by which the label undecided of an attacking argument is not always propagated to an otherwise accepted attacked argument.

An Automated Semantic Annotation Tool Supported by an Ontology in the Computer Science Domain

open access: yesProceedings of the 7th International Joint Conference on Knowledge Discovery, Knowledge Engineering and Knowledge Management, 2015
The annotation of documents can be performed manually, semi-assisted or automated, also it can use the help of different knowledge resources as a set of rules or ontology. In this paper, we show the design of a semantic annotation tool that works automatically on power in order to efficiently manage academic documents in spanish produced in ...

Serret-Frenet Frame and Curvatures of Bézier Curves

open access: yesMathematics, 2018
The aim of this study is to view the role of Bézier curves in both the Euclidean plane E 2 and Euclidean space E 3 with the help of the fundamental algorithm which is commonly used in Computer Science and Applied Mathematics and without ...

TRX: A Formally Verified Parser Interpreter [PDF]

open access: yesLogical Methods in Computer Science, 2011
Parsing is an important problem in computer science and yet surprisingly little attention has been devoted to its formal verification. In this paper, we present TRX: a parser interpreter formally developed in the proof assistant Coq, capable of producing

Co-evolutionary Game Dynamics of Competitive Cognitions and Public Opinion Environment

open access: yesFrontiers in Physics, 2021
Competitive cognition dynamics are widespread in modern society, especially with the rise of information-technology ecosystem. While previous works mainly focus on internal interactions among individuals, the impacts of the external public opinion ...

Formal Semantics and Formally Verified Validation for Temporal Planning [PDF]

open access: yesarXiv, 2022
We present a simple and concise semantics for temporal planning. Our semantics are developed and formalised in the logic of the interactive theorem prover Isabelle/HOL. We derive from those semantics a validation algorithm for temporal planning and show, using a formal proof in Isabelle/HOL, that this validation algorithm implements our semantics.

On More or Less Appropriate Notions of ‘Computation’

open access: yesSouth African Computer Journal, 2018
Half a century after the emergence of computer science (a.k.a. informatics) as an academic discipline, the notion of “computation” is not yet “settled”. On the contrary: recent developments in the natural sciences, in mathematics, as well as in computer ...

The global environmental agenda urgently needs a semantic web of knowledge

open access: yesEnvironmental Evidence, 2022
Progress in key social-ecological challenges of the global environmental agenda (e.g., climate change, biodiversity conservation, Sustainable Development Goals) is hampered by a lack of integration and synthesis of existing scientific evidence.
