![]() ![]() ![]() that Dresden is a city in Germany, or that a person, in the sense of that URI, can be fictional. ,, ) can be dereferenced and will result in further RDF graphs, describing the URI, e.g. In this example, all URIs, both for edges and nodes (e.g. According to the so-called Linked Open Data principles, such a dereferenced URI should result in a document that offers further data about the given URI. One of the advantages of using Uniform Resource Identifiers (URIs) is that they can be dereferenced using the HTTP protocol. Graph resulting from the RDFa example, enriched with further data from the Web The triples result in the graph shown in the given figure. The following HTML fragment shows how a small graph is being described, in RDFa-syntax using a vocabulary and a Wikidata ID: In the following example, the text "Paul Schuster was born in Dresden" on a website will be annotated, connecting a person with their place of birth. In 2013, more than four million Web domains (out of roughly 250 million total) contained Semantic Web markup. In 2006, Berners-Lee and colleagues stated that: "This simple idea…remains largely unrealized". The 2001 Scientific American article by Berners-Lee, Hendler, and Lassila described an expected evolution of the existing Web to a Semantic Web. The " intelligent agents" people have touted for ages will finally materialize. A "Semantic Web", which makes this possible, has yet to emerge, but when it does, the day-to-day mechanisms of trade, bureaucracy and our daily lives will be handled by machines talking to machines. I have a dream for the Web become capable of analyzing all the data on the Web – the content, links, and transactions between people and computers. īerners-Lee originally expressed his vision of the Semantic Web in 1999 as follows: While its critics have questioned its feasibility, proponents argue that applications in library and information science, industry, biology and human sciences research have already proven the validity of the original concept. The term was coined by Tim Berners-Lee for a web of data (or data web) that can be processed by machines -that is, one in which much of the meaning is machine-readable. According to the W3C, "The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries." The Semantic Web is therefore regarded as an integrator across different content and information applications and systems. These standards promote common data formats and exchange protocols on the Web, fundamentally the RDF. These embedded semantics offer significant advantages such as reasoning over data and operating with heterogeneous data sources. For example, ontology can describe concepts, relationships between entities, and categories of things. ![]() These technologies are used to formally represent metadata. To enable the encoding of semantics with the data, technologies such as Resource Description Framework (RDF) and Web Ontology Language (OWL) are used. The goal of the Semantic Web is to make Internet data machine-readable. The Semantic Web, sometimes known as Web 3.0 (not to be confused with Web3), is an extension of the World Wide Web through standards set by the World Wide Web Consortium (W3C). ![]()
