What is Web ontology language used for?
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.
What language is used in ontology?
Ontology languages are usually declarative languages, are almost always generalizations of frame languages, and are commonly based on either first-order logic or on description logic.
How is OWL used?
OWL allows you to tailor what you say based on the computational realities and application requirements, such as queries, rules, policy enforcement, etc. Further, OWL allows you to easily express relationships between different ontologies using a standard annotation framework.
What forms the constituents of ontology in Web ontology language?
Ontologies. An ontology consists of a set of axioms which place constraints on sets of individuals (called “classes”) and the types of relationships permitted between them. These axioms provide semantics by allowing systems to infer additional information based on the data explicitly provided.
What are the requirements for ontology languages?
The language should be compatible with other commonly used Web and industry standards. In particular, this includes XML and related standards (such as XML Schema and RDF), and possibly other modeling standards such as UML. Supported Tasks: Exchange of ontologies and data in a standard format.
What is the role of ontology?
In a nutshell, ontologies are frameworks for representing shareable and reusable knowledge across a domain. Their ability to describe relationships and their high interconnectedness make them the bases for modeling high-quality, linked and coherent data.
What are ontology axioms?
Axioms. assertions (including rules) in a logical form that together comprise the overall theory that the ontology describes in its domain of application. In these disciplines, axioms include only statements asserted as a priori knowledge. As used here, “axioms” also include the theory derived from axiomatic statements …
What are OWL axioms?
2.1. An OWL ontology in the abstract syntax is a sequence of axioms and facts, plus inclusion references to other ontologies, which are considered to be included in the ontology. In OWL a datatype denotes the set of XML Schema data values that is the value space for the datatype. Classes denote sets of individuals.
Does the Semantic Web need ontology?
Abstract: The Semantic Web relies heavily on formal ontologies to structure data for comprehensive and transportable machine understanding. Thus, the proliferation of ontologies factors largely in the Semantic Web’s success.
What are the ontologies on the Semantic Web?
In the environment of the Semantic Web, then, an ontology is a partial conceptualization of a given knowledge domain, shared by a community of users, that has been defined in a formal, machine‐processable language for the explicit purpose of sharing semantic information across automated systems.
What is OWL Web Ontology?
The Ontology Web Language (OWL) is a set of markup languages which are designed for use by applications that need to process the content of information instead of just presenting information to humans. The OWL ontology describe the hierarchical organization of ideas in a domain, in a way that can be parsed…
What’s is ontology of programing language?
In computer science and artificial intelligence, ontology languages are formal languages used to construct ontologies. They allow the encoding of knowledge about specific domains and often include reasoning rules that support the processing of that knowledge. May 21 2019
