The Web Ontology Language (OWL) is a family of knowledge representation languages for authoring ontologies.Ontologies are a formal way to describe taxonomies and classification networks, essentially defining the structure of knowledge for various domains: the nouns representing classes of objects and the verbs representing relations between the objects.
Example of a constructed MBED Top Level Ontology based on the nominal set of views. [1]In computer science, information science and systems engineering, ontology engineering is a field which studies the methods and methodologies for building ontologies, which encompasses a representation, formal naming and definition of the categories, properties and relations between the concepts, data and ...
Top-level Ontology Chart. In information science, an ontology encompasses a representation, formal naming, and definitions of the categories, properties, and relations between the concepts, data, or entities that pertain to one, many, or all domains of discourse. More simply, an ontology is a way of showing the properties of a subject area and ...
OWL. Gellish is an example of a combined ontology language and ontology that is description logic based. It distinguishes between the semantic differences among others of: relation types for relations between concepts (classes)
It involves publishing in languages specifically designed for data: Resource Description Framework (RDF), Web Ontology Language (OWL), and Extensible Markup Language . HTML describes documents and the links between them. RDF, OWL, and XML, by contrast, can describe arbitrary things such as people, meetings, or airplane parts.
The exception is the root which is a particular agent often labelled ‘society’ and located on the extreme left of an ontology chart. The root is often dropped in practice but is implied in every ontology chart. If any other particular is present in an ontology chart it is recognised by the ‘#’ sign prefix and upper case letters.
OWL-S is an ontology built on top of Web Ontology Language (OWL) by the DARPA DAML program. [1] It replaces the former DAML-S ontology. "OWL-S is an ontology, within the OWL-based framework of the Semantic Web, for describing Semantic Web Services. It will enable users and software agents to automatically discover, invoke, compose, and monitor ...
Hoolet, an implementation of an OWL-DL reasoner that uses a first order prover supports SWRL. Pellet, an open-source Java OWL DL reasoner has SWRL-support. KAON2 is an infrastructure for managing OWL-DL, SWRL, and F-Logic ontologies. RacerPro, supports the processing of rules in a SWRL-based syntax by translating them into nRQL rules
