Ontology Engineering 2nd ed.

The Second Edition of An Introduction to Ontology Engineering provides an updated comprehensive overview of ontology engineering, and offers hands-on experience that illustrate the theory. The topics covered include: logic foundations for ontologies with languages and automated reasoning, developing good ontologies with methods and methodologies, the top-down approach with foundational ontologies, and the bottom-up approach to extract content from existing material, and a selection of advanced topics that includes Ontology-Based Data Access, the interaction between ontologies and natural languages, advanced modelling languages, and modularisation, matching, and more. Each chapter contains review questions and exercises.

The textbook is aimed at advanced undergraduate/postgraduate level in computer science and could fit a semester course in ontology engineering or a 2-week intensive course. Domain experts and philosophers may find a subset of the chapters of interest, or work through the chapters in a different order.

Maria Keet is the R&D Manager of Meaningfy since 2025. Before that, she was an Associate Professor with the Department of Computer Science, University of Cape Town, South Africa.

She received her PhD in Computer Science in 2008 at the KRDB Research Centre, Free University of Bozen-Bolzano, Italy. Her research focus is on knowledge engineering with ontologies and Ontology, and their interaction with natural language and conceptual data modelling, which has resulted in over 150 publications. She has developed and taught multiple courses on ontology engineering and related topics since 2009, and the first edition of this book received the UCT Open Textbook Award.
