RgbDF: Resource Goal and Behaviour Description Framework
2006
Agent-oriented approach has proven to be very efficient in engineering complex distributed software environments with dynamically changing conditions. The efficiency of underlying modelling framework for this domain is undoubtedly of a crucial importance. Currently, a model-driven architecture has been the most popular and developed for purposes of modelling different aspects of multi-agent systems, including behaviour of individual agents. UML is utilized as a basis for this modelling approach and variety of existing UML-based modelling tools after slight extension are reused. This paper proposes an ontology-driven approach to modelling agent behaviour as an emerging paradigm that originat…
Future Research Directions on Web-Based Educational Systems
2018
Over the last decade, following the rapid progress of Information and Communication Technology (ICT) and directly linked to the requirements of the Information Society, Web-based education has turned into an essential branch of educational technology. Although the traditional educational systems continue to improve, the gradual transition to Semantic Web, that is currently taking place, facilitates the emergence of new opportunities for improving the quality of educational processes. The distributed instruction, the explosive expansion of social networks and the significant increase in the number of mobile users represent phenomena that have led to new trends in the evolution of educational…
Reasoning with Multilevel Contexts in Semantic Metanetworks
2000
It is generally accepted that knowledge has a contextual component. Acquisition, representation, and exploitation of knowledge in context would have a major contribution in knowledge representation, knowledge acquisition, and explanation, as Brezillon and Abu-Hakima supposed in [Brezillon and Abu-Hakima, 1995]. Among the advantages of the use of contexts in knowledge representation and reasoning Akman and Surav [Akman and Surav, 1996] mentioned the following: economy of representation, more competent reasoning, allowance for inconsistent knowledge bases, resolving of lexical ambiguity and flexible entailment. Brezillon and Cases noticed however in [Brezillon and Cases, 1995] that knowledge-…
Introduction to semantic knowledge base: Linguistic module
2013
Following paper presents main concepts of Semantic Knowledge Base in particular linguistic module. The main assumption is to develop solution that would be easily adoptable by various languages. The module design will be presented in Association Oriented Model to maintain inner compatibility of the Knowledgebase.
Knowledge-driven multi-agent simulation engineering for assessing the effectiveness of disaster management plans
2020
Protecting humans from disasters has been an active mission of governments and experts through the definition of disaster management plans. Defining disaster response strategies is crucial in order to reduce the number of victims and the economic impact. In order to select which response plan is best suited to a specific disaster situation, these plans must be evaluated. However, such evaluation is limited by the high cost of exercises and the specificity of existing simulation models. The approach defended in this thesis combines techniques from Semantic Web and multi-agent simulation to evaluate disaster management response plans. It is composed of four steps : (1) modeling disaster manag…
A Novel User Interface for Knowledge Base Browsing
2019
Abstract Intuitive user interfaces have been of great concern for GUI developers. The current research, who deals with their designing, faces the term intuitive constantly. The main question is how can the Interface be intuitive? For the moment, the researchers try to provide a very intuitive generic user interface that can be used in a variety of applications. In this paper we provide a solution that can model any applied ontology into a honeycomb menu. The hexagonal shape of the honeycomb has attracted the attention of humans for centuries. As a relevant consequence, the final user can browse any knowledge base very easily with the aid of this interface. Another useful feature is that pro…
Semantic infrastructure system with feedback: Application on traffic
2012
The Semantic Web is a powerful approach used by some intelligent applications to manage complex information in many different fields. Nevertheless, there are not standard tools to design and built the applications, therefore each problem need to be analysed separately in order to meet the requirements. In this paper is presented an overview of a system based on a semantic approach with the goal of managing real-time information. The paper studies the application of this system on ITS (Intelligent Transport Systems) as an example of a typical real-time information system. The system gathers real information from the users and the environment, making intelligent decisions and delivering real-…
A precise measurement of the Z resonance parameters through its hadronic decays
1990
A measurement of the cross section for e+e-→ hadrons using 11 000 hadronic decays of the Z boson at ten different center-of-mass energies is presented. A three-parameter fit gives the following values for the Z mass MZ, the total width ΓZ, the product of the electronic and hadronic partial widths ΓeΓh, and the unfolded pole cross section σ0: MZ = 91.171 ± 0.030 (stat.) ± 0.030 (beam) GeV, ΓZ = 2.511 ± 0.065 GeV, ΓeΓh = 0.148 ± 0.006 (stat.) ± 0.004 (syst.) GeV2, σ0 = 41.6 ± 0.7 (stat.) ± 1.1 (syst.) nb, Good agreement with the predictions of the standard model is observed. From a two-parameter fit the number of massless neutrino generations is found to be Nv = 2.91 ± 0.26. Thus the hypothes…
Integration, Bewertung und Nutzung heterogener Datenquellen mittels semantischer Werkzeuge
2017
In diesem Artikel stellen wir unsere Forschung in der Integration von Geodaten in einen Semantic Web Kontext in unserem Projekt Semantic GIS vor. Zunächst möchten wir den Zweck und die Vorteile einer Integration und Interpretation von Daten in das Semantic Web beleuchten und anschließend unseren Integrationprozess bestehend aus Datengewin-nung, automatischer Interpretation, Qualitätssicherung und Provenance sowie den Datenzugriff erklären. Um die Anwendung unserer Forschung zu demonstrieren gehen wir auf zwei Anwendungsfälle in unserem Projekt ein: Die Bewertung von OpenStreetMap Daten und die Verbesserung des Katastrophenschutzes mittels semantischem Reasoning. Wir schließen den Artikel mi…
Ontology mapping specification in description logics for cooperative systems
2006
Le developpement rapide du Web semantique est lie a la specification de plus en plus d'ontologies. Celles-ci permettent de modeliser des connaissances agreees par des communautes de personnes concernant des domaines ou des tâches specifiques. Le meme domaine decrit par deux communautes distinctes sera modelise de facon differente. Les systemes cooperatifs visent a rendre les informations provenant de differentes sources disponibles au-dela de leurs divergences. Pour cela, ils doivent aligner, fusionner ou integrer ces ontologies. La decouverte de mappings est un point cle dans la resolution efficace des heterogeneites entre ontologies. Nous developpons une architecture qui connecte des syst…
