How can we use ontology in Semantic Web?
As one of the building blocks of Semantic Technology, ontologies are part of the W3C standards stack for the Semantic Web. They provide users with the necessary structure to link one piece of information to other pieces of information on the Web of Linked Data.
What is ontology and Semantic Web?
Ontology means describing the semantics of the data, providing a uniform way to enable communication by which different parties can understand each other. • Logic and Proof: In the Semantic Web, the building of systems follows a logic which considers the structure of ontology.
What is the difference between semantics and ontology?
Indeed, these are two different things: semantics is a fields. It studies the meaning of languages (Wikipedia has a nice definition http://en.wikipedia.org/wiki/Semantics#Computer_science). Ontologies are representation of the knowledge (also see Wikipedia: http://en.wikipedia.org/wiki/Ontology_(information_science)).
What is Semantic Web in DBMS?
The Semantic Web is a mesh of data that are associated in such a way that they can easily be processed by machines instead of human operators. It can be conceived as an extended version of the existing World Wide Web, and it represents an effective means of data representation in the form of a globally linked database.
What is Semantic Web example?
Examples include Best Buy, BBC World Cup site, Google, Facebook and Flipboard. Google, Microsoft, Yahoo and Yandex agree on Schema.org, a vocabulary for associating meaning to data on the web. The vocabulary is defined by a community process.
What is ontology in semantics?
Ontological semantics, an integrated complex of theories, methodologies, descriptions, and implementations, attempts to systematize ideas about both semantic description as representation and manipulation of meaning by computer programs.
Where are ontologies used?
One major advantage of using a domain ontology is its ability to define a semantic model of the data combined with the associated domain knowledge. Ontologies can also be used to define links between different types of semantic knowledge. Thus, ontologies can be used in formulating some data searching strategies.
What is relation in ontology?
Relationships (also known as relations) between objects in an ontology specify how objects are related to other objects. Typically a relation is of a particular type (or class) that specifies in what sense the object is related to the other object in the ontology.
What is the difference between ontology and vocabulary?
The trend is to use the word “ontology” for more complex, and possibly quite formal collection of terms, whereas “vocabulary” is used when such strict formalism is not necessarily used or only in a very loose sense. Vocabularies are the basic building blocks for inference techniques on the Semantic Web.
Is there a tutorial on translation between ontologies in multi-agent systems?
This tutorial is extracted from the introductory chapter of the dissertation that deals with the applications of ontologies in multi-agent systems – Marek Obitko (advisor Vladimir Marik): Translations between Ontologies in Multi-Agent Systems, Ph.D. dissertation, Faculty of Electrical Engineering, Czech Technical University in Prague, 2007.
What is the role of Vocabularies on the Semantic Web?
The role of vocabularies on the Semantic Web are to help data integration when, for example, ambiguities may exist on the terms used in the different data sets, or when a bit of extra knowledge may lead to the discovery of new relationships. Consider, for example, the application of ontologies in the field of health care.
Where can I find a list of semantic web books?
The Semantic Web community maintains a list of books on a W3C Wiki page. Some of those books are introductory in nature while others are conference proceedings or textbook that address more advanced topics.
