Ontology and Ontology Construction: Background and Practices

When developing semantic applications, constructing the underlying ontologies is a crucial part. This paper presents a view-point on the notion of ‘ontology’ and of ontology construction. Ontology construction cannot be seen in isolation, but must be considered in relation to its use. We also present two ways of conceiving ontology construction and ultimately, we survey common categories in the construction methods of ontology learning.
