Ontology development avails of science, engineering, and philosophy to represent the subject domain knowledge formally so that it can be used to enhance information systems. This process involves resolving ontological differences and making choices between conflicting axioms, which are due to various reasons. Examples include different foundational ontologies, alternate design patterns for the prospective ontology’s use case, and an ontology language’s expressivity limitations.

Instead of ad hoc decision-making, science and engineering-based modeling guidance with methods and tools can alleviate these issues to assist with the meaning negotiation and conflict resolution in a systematic way. In this talk, I will discuss common conflicts and typical steps toward resolution, including the tool availability for it. A similar situation with trade-offs exist when deploying ontologies for ontology-based data access and integration, which we shall touch upon as well. Use cases, tools, and experiments were in several subject domains, such as avian influenza, horizontal gene transfer, and metabolic pathways.


C. Maria Keet (PhD, MSc, MA, BSc(hons)) is an Associate Professor with the Department of Computer Science, University of Cape Town. She focuses on ontology engineering, conceptual data modelling, and their interaction with natural language, which has resulted in over 100 peer-reviewed publications at venues including KR, FOIS, K-CAP, EKAW, ESWC, ER, CIKM, Applied Ontology, and the Semantic Web Journal. She is PI on two NRF-funded projects on NLG for Nguni languages, and was PI on an DST/MINCyT-funded bi-lateral project with Argentina on ontology-driven conceptual modelling. She was involved in several EU projects, coordinated the development of several tools, and has written the first textbook on ontology engineering for computer scientists. She has served on many Program Committees of international workshops and conferences and reviewed for numerous journals; recently she has been a (PC or local) chair for EKAW2020, FOIS2018, and the IJCAI 2021 Demo track.

Before her employment at UCT, Maria was Senior lecturer at the University of KwaZulu-Natal, South Africa, and a non-tenured Assistant Professor at the KRDB Research Centre, Free University of Bozen-Bolzano, Italy where she also obtained a PhD in Computer Science in 2008. She also holds a BSc(honours) 1st class in IT & Computing from the Open University UK (2004), an MSc in Food Science (Microbiology) from Wageningen University, the Netherlands (1998), and an MA 1st class in Peace & Development Studies from the University of Limerick, Ireland (2003).

Community Challenges

  • Continuous Evaluation of Relational Learning In Biomedicine is a new challenge which aims to continuously evaluate prediction methods as new biological knowledge becomes available

  • Predict biological relations between biological entities using three different knowledge graphs

  • New relations are retrieved in regular intervals using SPARQL queries and prediction results automatically evaluated against the query results
