KnowledgE ENgineering team
Funded projects - Recent highlights - Members and collaboratorsThe aim of the team's activities is to contribute computing theory, methods, and techniques to the knowledge society.
The scope of the KEEN team is knowledge engineering in its broad sense. This includes ontology engineering, the Semantic Web, intelligent (logic-based, ontology-driven) conceptual modelling, and natural language generation.

Recent highlights
- Zola Mahlaza, in collaboration with Tadiwa Magwenzi, Maria Keet, and Langa Khumalo, had a paper accepted at INLG'24, on automatically generating isiZulu words from Indo-Arabic numerals, which will be presented at the conference in Tokyo, Japan, September 23-27, 2024.
