Is OWL an ontology?

Is OWL an ontology?

Overview. The W3C Web Ontology Language (OWL) is a Semantic Web language designed to represent rich and complex knowledge about things, groups of things, and relations between things. OWL is part of the W3C’s Semantic Web technology stack, which includes RDF, RDFS, SPARQL, etc.

What are the versions of OWL?

The W3C-endorsed OWL specification includes the definition of three variants of OWL, with different levels of expressiveness. These are OWL Lite, OWL DL and OWL Full (ordered by increasing expressiveness). Each of these sublanguages is a syntactic extension of its simpler predecessor.

What are the components within an OWL ontology?

Basic Elements. Most of the elements of an OWL ontology concern classes, properties, instances of classes, and relationships between these instances.

Is RDF an ontology?

RDF Schema (RDFS) is a language for writing ontologies. An ontology is a model of (a relevant part of) the world, listing the types of object, the relationships that connect them, and constraints on the ways that objects and relationships can be combined.

Which is not ontology language?

In fact OWL is not one ontology language, but a set of three sublanguages: OWL Lite, the light version. OWL Lite is designed for basic needs and could be used to convert thesauri and taxonomies into ontologies.

What does OWL stand for?

Where does a barn owl hunt at night?

Barn Owls nest and roost in cavities, abandoned barns and other buildings, and dense trees. At night, Barn Owls hunt by flying low, back and forth over open habitats, searching for small rodents primarily by sound. Barn Owls require large areas of open land over which to hunt. This can either be marsh, grasslands, or mixed agricultural fields.

Gray and cinnamon above and white below, although some have cinnamon colored and spotty chests. White heart-shaped face and dark eyes are distinctive. During hard winters, or in times of food shortages, Barn Owls sometimes hunt during the day, often frequenting the same open country habitats used by Northern Harriers.

What was the scientific name of the barn owl?

He gave it the scientific name Strix alba. As more species of owl were described, the genus Strix came to refer solely to the wood owls in the typical-owl family Strigidae; and the barn owl became Tyto alba in the barn-owl family Tytonidae.

Where are barn owls found in the world?

Regional Differences. Barn Owls have a worldwide distribution with substantial variation in size and in the patterns of buff and white in the plumage. However, the subspecies found in the United States and Canada does not show substantial geographic variation.
