Very clear explanation, Adam! Thank you for sharing.

Thanks! I hope you enjoy some of my other ontology videos as well.

Thanks for the video, but I still have some questions left : How are ontologies used in practice? like how are they embedded in a process? And also, are ontologies all about knowledge representation in a graph? you said that computers are using ontologies, but are they accessing the graph to get the information it needs?

The most common application I've done commercially with ontology is in providing metadata. An ontology provides computable constraints on the meaning of terms used in databases or catalogs. Graphs are one approach that are very popular but they can only represent named relations between two things. There are more types of knowledge in the world than that, so I use an expressive mathematical logic. There's a lot more information in my longer video kzread.info/dash/bejne/lnVr0s-JqKeyqrA.html and book www.adampease.org/OP/Book.html

Interesting, could you add some more videos on Ontology?

There are lots more videos now :-) I'd be eager to know what you think and if there are helpful to you.

Activities such as ontology merging and ontology alignment is part of which step during the knowledge acquisition phase : A. Extraction B. Evaluation C. Integration D. Configuration Management

It depends on the ontologies you are using. Many things that are called ontologies don't have the formal definitions that SUMO does, so the first step is to determine the meaning of the terms that you want to integrate with SUMO, even informally as a dictionary definition. Then determine which of them SUMO already covers, or which can't be defined and should be discarded. A good case study and overview is www.semantic-web-journal.net/system/files/swj2520.pdf

Which is the right order of the activities for the development of ontologies ? A. Specification , Formalisation, Conceptualisation, Implementation B. Specification , Conceptualisation, Formalisation ,Implementation C. Conceptualisation, Specification, Formalisation ,Implementation D. Formalisation ,Specification , Conceptualisation, Implementation
