What is ontology and Semantic Web?

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 an example of Semantic Web?

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 the Semantic Web concept?

The Semantic Web is a vision about an extension of the existing World Wide Web, which provides software programs with machine-interpretable metadata of the published information and data. In other words, we add further data descriptors to otherwise existing content and data on the Web.

What is the main aim of Semantic Web?

The standard promotes common data formats on the World Wide Web. By encouraging the inclusion of semantic content in web pages, the Semantic Web aims at converting the current web dominated by unstructured and semi-structured documents into a “web of data” — that it can be read directly by the computers.

What are ontologies used for?

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.

How do you make ontologies?

Tips for Creating an Ontology

1. Determine the domain and scope of the ontology.
2. Consider reusing existing ontologies.
3. Enumerate important terms.
4. Define the classes & class hierarchy.
5. Define the properties of classes.
6. Define the facets of the slots.
7. Create instances.

Is Facebook a semantic website?

A TRULY meaningful way of interacting with the web may finally be here, and it is called the semantic web. The idea was proposed over a decade ago by Tim Berners-Lee, among others.

How does Semantic Web different from the normal web?

As such, the fundamental difference between Semantic Web technologies and other technologies related to data (such as relational databases or the World Wide Web itself) is that the Semantic Web is concerned with the meaning and not the structure of data.

What is the difference between ontology and semantics?

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 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.

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.

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.
