1. An ontology of computing

2. 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. http://tomgruber.org/writing/ontolingua-kaj-1993.htm

4. 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.

5. Why - Computing Ontology Beyond the general reasons for an ontology of anything Computing is a broad category of disciplines – Computer Science – Computer Engineering – Software Engineering – Artificial Intelligence – Information Science – Information Systems – Information Technology – More … Good for increased attention to special topics within the domains Potentially weakens the voice of the overall domain
