An ontology of computing
What is an ontology?
• An ontology is a specification of a
conceptualization.
• A specification of a representational vocabulary for
a shared domain of discourse — definitions of
classes, relations, functions, and other objects — is
called an ontology.

From Wikipedia,
the free encyclopedia
Ontologies are the structural frameworks for organizing
information and are used in artificial intelligence, the
Semantic Web, systems engineering, software engineering,
biomedical informatics, library science, enterprise
bookmarking, and information architecture as a form of
knowledge representation about the world or some part of it.
The creation of domain ontologies is also fundamental to the
definition and use of an enterprise architecture framework.
Why - Computing Ontology
• Beyond the general reasons for an ontology of anything
• Computing is a broad category of disciplines

• With a partner, choose a topic area to classify
– Go to Blackboard and fill in the classification for your topic
– Then choose another topic and repeat. Please do not choose both
at once, so that there is more freedom of choice for everyone.
