What is semantic web

The Semantic Web combines a set of new technologies with

grounded knowledge representation techniques to address the

needs of more formal information modelling and reasoning for web-

based services

Its a collaborative movement led by the World Wide Web Consortium (W3C)

Stack built on the builds on the W3C's Resource Description

Framework (RDF)

We are now talking about Web 3.0

Definition

The Semantic Web provides a common framework that allows data to

be shared and reused across application, enterprise, and community

boundaries.

-W3C

Building Blocks

Semantic Web Layer Cake Source: W3C

RDF: It describes Resources through a series of

Statements. Each statement is a Property and Value

that is about a Resource.

OWL: Web Ontology Language, informally OWL, is a

declarative knowledge representation language for

the Semantic Web with formally defined meaning for

creating ontologies.

SPARQL: It’s a query language for RDF.

RIF: Rule Interchange Format family of specifications

focuses on exchange rather than a single one-fits-all.

Benefits

Consistent mechanisms to model information from simple

vocabularies to complex ontologies.

A formal model approach ensures information reasoning outcomes.

Data linking opportunities aimed at supporting better user

experiences, and hence, improved business outcomes.

A groundswell of activity in the development of open-source tools

to exploit Semantic Web technologies and information

Standardised by the W3C indicating global consensus and open

royalty-free specifications
