The World of Artificial Intelligence

Ontologies and Knowledge Sharing

An Ontology, in the world of Artificial Intelligence, is a specification of a conceptualisation (a description of concepts and connections among them that can exist for a community). It is certainly a different sense of the word than its use in philosophy.  What is important is what an ontology is for.  A key purpose of ontologies is knowledge sharing and reuse.  A conceptualisation is an abstract, simplified view of the world that we wish to represent for some purpose.  To specify a conceptualisation one needs to state axioms that do constrain the possible interpretations for the defined terms.[1]  An Ontology’s meta model is where it contributes most to OBC.  Upper Ontologies, which specify common things like time, location and measurements, contribute greatly to OBC Topic 5.
