Ontology Engineering lecture notes for 2014 online

The lecture notes for the Ontology Engineering BSc honours in CS course are available online now. The file is updated compared to the COMP720 module (and those notes have been removed). The main changes consist of reordering the chapters in Block II and Block III, adding better or more explanations and examples in several sections, fixing typos, and updates to reflect advances made in the field. It again includes the DL primer written by Markus Kroetzsch, Ian Horrocks and Frantisek Simancik (saving me the time writing about that; thanks!).

As with the last three installments, the target audience is computer science students in their 4th year (honours), so the notes are of an introductory nature. It has three blocks after the introduction: logic foundations, ontology engineering, and advanced topics (the latter we will skip, as this is a shorter course). The logic foundations contain a recap of FOL and the notion of reasoning, the DL primer and the basics of automated reasoning with the Description Logics with ALC, the DL-based OWL species, and some practical automated reasoning. The ontology engineering block starts with methods and methodologies that give guidance how to commence actually developing an ontology, and how to avoid and fix issues. Subsequently, there are two chapters going into some detail of two ‘paths’ in the methodology, being top-down ontology development using foundational ontologies, and bottom-up ontology development to extract knowledge from other material, such as relational databases, thesauri, and natural language documents.

The advanced topics are optional this year, but I left them in the lecture notes, as they may pique your interest. Chapter 8 on Ontology-Based Data Access is a particular application scenario of ontologies that ‘spice up’ database applications. Chapter 9 touches upon a few sub-areas within ontologies: representing and reasoning with vagueness and uncertainty, extending the language to include also temporal knowledge, the use of ontologies to enhance conceptual data models, and a note on social aspects.

It is still an evolving document, and relative completeness of sections varies slightly, so it has to be seen in conjunction with the slides, lectures, and some additional documentation that will be made available on the course’s Vula site.

Suggestions and corrections are welcome! If you want to use a part of it in your own lectures and/or use the accompanying slides with it, please contact me.
