Author: Burke, Ivan D ; Van Heerden, Renier P Date: Mar 2016 Cyber awareness training has become a growing industry, with more and more organisations starting to focus on training personnel on how to behave in a secure manner when engaging in cyber operations. Cyber challenges place participants in ... Read more
BFO Classifier: Aligning domain ontologies to BFO

Author: Emeruem, C ; Keet, CM ; Dawood, Zubeida C ; Wang, S Date: Aug 2022 Foundational ontologies are known to have a steep learning curve, which hampers casual use by domain ontology developers to use them for domain ontology development. Foundational ontology developers have not provided methods or tools to lower ... Read more
Categorising cyber security threats for standardisation

Author: Dawood, Zubeida C Date: Mar 2019 Computer Security Incident Response Teams (CSIRTs) are responsible for data collection and analysis concerning cyber security threat incidents. In order to provide the best service support for cyber security breaches, information about how ... Read more
The current landscape of pitfalls in Ontologies

Author: Keet, CM ; Suarez-Figueroa, MC ; Poveda-Villalon, M Date: Sep 2013 A growing number of ontologies are already available thanks to development initiatives in many different fields. In such ontology developments, developers must tackle a wide range of difficulties and handicaps, which can result in the appearance ... Read more
Cyber-threat information-sharing standards: A review of evaluation literature

Author: Mkuzangwe, Nenekazi N ; Dawood, Zubeida C Date: Jun 2020 Cyber-threat information-sharing tools, through which cybersecurity teams share threat information, are essential to combatting today's increasingly frequent and sophisticated cyber-attacks. Several cyber-threat information-sharing standards ... Read more
Enriching behavioural biometrics experiments with an ontology

Author: Dawood, Zubeida C Date: Feb 2019 Behavioural biometrics are increasingly being used to authenticate users for various applications. As active research is being conducted for behavioural biometrics, researchers face difficulty in sharing and annotating experimental data. This ... Read more
Finding EL+ justifications using the Earley parsing algorithm

Author: Nortje, R ; Britz, K ; Meyer, T Date: Dec 2009 Module extraction plays an important role in the reuse of ontologies as well as in the simplification and optimization of some reasoning tasks such as finding justifications for entailments. In this paper the authors focus on the paper of ... Read more
First steps in the computation of root justifications

Author: Meyer, T ; Moodley, K ; Varzinczak, I Date: Aug 2010 Description Logics (DLs) are widely accepted as an appropriate class of knowledge representation languages to represent and reason about ontologies. Tools for performing standard reasoning tasks such as satisfiability and consequence checking ... Read more
The foundational ontology library ROMULUS

Author: Dawood, Zubeida C ; Keet, CM Date: Sep 2013 A purpose of a foundational ontology is to solve interoperability issues among domain ontologies and they are used for ontology- driven conceptual data modelling. Multiple foundational ontologies have been developed in recent years, and most ... Read more
Integration of SNOMED CT into the OpenMRS electronic medical record system framework

Author: Gerber, A ; Meyer, T ; Seebregts, C ; Britz, A ; Pretorius, L ; Alberts, R ; Moodley, D ; Halland, K Date: Nov 2008 Integrating a mechanism to store, retrieve and use clinical data with a system to manage medical records enables better utilisation of medical data and improved healthcare. This poster introduces a research project that aims to extend OpenMRS ... Read more
iSemServ: A model-driven approach to developing semantic web services

Author: Mtsweni, Jabu S ; Biermann, E ; Pretorius, L Date: Jul 2014 The benefits of incorporating Semantic Web Services in web applications are well documented. However, both the real-world implementation and adoption of these services are still rather limited in practice. This is despite the promises that ... Read more
A knowledge-based system for discovering ecological interactions in biodiversity data-stores of heterogeneous specimen-records: a case-study of flower-visiting ecology

Author: Coetzer, W ; Moodley, D ; Gerber, A Date: Nov 2014 We modeled expert knowledge of arthropod flower-visiting behavioral ecology and represented this in an event-centric domain ontology, which we describe along with the ontology construction process. Two smaller domain ontologies were created ... Read more
A knowledge-based system for generating interaction networks from ecological data

Author: Coetzer, W ; Moodley, D ; Gerber, A Date: Nov 2017 Semantic heterogeneity hampers efforts to find, integrate, analyse and interpret ecological data. An application case-study is described, in which the objective was to automate the integration and interpretation of heterogeneous, flower-visiting ... Read more
Modelling of the complex societal problem of establishing a national energy sufficiency competence

Author: Roodt, JH ; Leenen, L ; Van Vuuren, JJ ; Dawood, Zubeida C Date: Jul 2020 Complex societal problems require a multidisciplinary and multi-method approach to develop models that can support the development of solutions. General morphological analysis is a qualitative method to extract information from experts through ... Read more
Modelling the cybersecurity environment using morphological ontology design engineering

Author: Jansen van Vuuren, JC ; Leenen, L ; Grobler, MM ; Chan, Ka Fai P ; Dawood, Zubeida C Date: Mar 2015 Acquiring, representing, and managing knowledge effectively has a considerable impact on constructing accurate and intelligent systems. A challenge faced by domain experts is the manner in which information about the cybersecurity environment ... Read more
Module-theoretic properties of reachability modules for SRIQ

Author: Nortje, R ; Britz, K ; Meyer, T Date: Jul 2013 In this paper we investigate the module-theoretic properties of bot and top-reachability modules in terms of inseparability relations for the DL SRIQ. We show that, although these modules are not depleting or self-contained, they share the ... Read more
An ontological knowledge base for cyber network attack planning

Author: Chan, Ka Fai P ; Theron, J ; Van Heerden, Renier P ; Leenen, L Date: Mar 2015 In modern warfare it is no longer sufficient to only focus on physical attacks and counter-measures; the threat against cyber networks is becoming increasingly significant. Modern military forces have to provide counter measures against these ... Read more
An ontology for regulating eHealth interoperability in developing African countries

Author: Moodley, D ; Seebregts, CJ ; Pillay, AW ; Meyer, T Date: Aug 2013 eHealth governance and regulation are necessary in low resource African countries to ensure effective and equitable use of health information technology and to realize national eHealth goals such as interoperability, adoption of standards and ...
